Which sentence best describes what happens after sunlight hits photosystem
II?
A. Solar energy changes ADP into ATP.
B. NADPH turns into NADP+.
C. Glucose forms from carbon dioxide molecules.
O D. Electrons in the third protein gain new energy from light.
Answer:
A. Solar energy changes ADP into ATP.
Explanation:
The phase of the photosynthesis is based on the light that reacts as the pigment molecule absorbs energy from the sunlight and the photons strike the photosystem to initiate the photosynthesis. Energy transports through the electron that pumps hydrogen ions and forms an electrochemical gradient. The ADP is a combination of phosphate to form the ATP in the reaction i.e ADP +energy to ATP plus water. This usually takes place by the storage of high energy to ATP as sugar molecules that are sent phase of photosynthesis.Answer:
A. Solar energy changes ADP into ATP
Explanation:
Photosynthesis is the process in which plants make there own food by utilizing sunlight that converts water and oxygen into carbon dioxide and energy.
There are two systems in photosynthesis: Photosystem II and Photosystem I.
In photosystem II ADP + P is converted into ATP driven by electron gradients formed in the thylakoid membrane.
Hence, the correct answer is A.

The punnets square shows a text cross of mice that are heterozygous for both traits what will the offspring be fill in the white boxes of the punnets square with all the possible offspring genotypes
Answer:
Explanation:
Dominant allele are allele that finds expression the offspring physical expression while recessive allele are alleles that are not expressed in the offspring phenotype.
the “good genes hypothesis” proposes that people with physical qualities like averageness, symmetry, sex prototypicality, and youthfulness are more attractive because they are better-quality mates. the “good genes hypothesis” is from which approach to psychology?: 1) evolutionary 2) psychodynamic 3) cognitive 4) biological
The correct answer is 1) Evolutionary
Explanation:
The "good genes hypothesis" argues traits of the opposite sex that are considered as positive or attractive reflect evolutionary traits and therefore are indicators of a better-quality mate. Indeed, this theory argues attraction is connected to better chances of survival or better chances to reproduce. This belongs to the evolutionary approach in psychology because these "attractive" traits are the result of evolution because only the "fittest" individuals reproduce and their genes prevail over time.
g A variable trait in corn is the presence or absence of knobs at particular sites on some chromosomes. The allele present on each chromosome determines whether or not that chromosome has a knob. Suppose that one member of each of two pairs of homologs in a corn plant has a knob. If this plant is crossed with a knobless plant, what percentage of the offspring is expected to have only knobless chromosomes
Answer:
50%
Explanation:
The allele present on each chromosome determines whether or not that chromosome has a knob. Suppose that one member of each of two pairs of homologs in a corn plant has a knob.
This means that on a chromosome with two chromatids, the allele present on one chromatid causes the chromatid to possess knob while the other does not making the plant an heterozygous...
If this plant is crossed with a knobless plant, one whose Chromebook is without knobs, we have
II x II
II - 50% with a knobbed chromatid
II - 50% with only knobless chromosomes.
The first to the left is knobbed, thus the percentage of offspring expected to have only knobless chromosomes would be 50%.
Assuming a diallelic gene and complete dominance, the percentage of the offspring that is expected to have only knobless chromosomes is 50%
----------------------------
Available data:
Trait presence absence of knobsPlant 1: One member of each of two pairs of homologs in a corn plant has a knobPlant 2: knobless plantWe will assume complete dominance, and that the presence of knobs is the dominant trait.
We will name the dominant allele A, and the recessive allele a.
Plant 1 seems to be heter0zyg0us for the trait, while plant 2 is h0m0zyg0us.
Cross: Plant 1 with Plant 2
Parentals) Aa x aa

Fur color in mice is affected by a single gene. The gene for fur color has two alleles: B that causes dark brown fur, and b that causes light brown fur. In a mouse with dark brown fur, the genotype could be BB or:_________
Answer:
The genotype could be BB or Bb
Explanation:
The genotype could be Bb which means it has heterozygous alleles.
The B which is allele for dark brown fur is dorminant and b for light brown is recessive. In this case, the dorminant allele masked the effect of the recessive allele b which make the dorminant allele B to be expressed phenotypically.

What occurs during frameshift mutation?
A) Part of the chromosome breaks away, but reattaches normally.
B) Part of the chromosome breaks away, but reattaches in inverse orientation.
C) An extra chromosome is added, causing mismatching of the chromosome pairs.
D) There is a misreading of the base pairs during translation.
Answer:
C) An extra chromosome is added, causing mismatching of the chromosome pairs.
Explanation:
Mutation is any change, whether big or small, that occurs in the nucleotide sequence of a gene. Mutation can be of different types depending on how it occurs.
According to the question, frameshift mutation is a mutation that causes the normal reading frame of the nucleotide sequence to be altered. It is caused when an extra chromosome is added (insertion) or when one chromosome is removed (deletion). In either way, there will be a mismatch or alteration in the chromosome pair, hence affecting the reading of the nucleotide sequence.
In frameshift mutation, the insertion or deletion causes the
normal CODONS (triplet nucleotide) to be missing or incomplete, hence, disrupts the manner at which the reading takes place (reading frame). Note, frameshift mutation only occurs as a result of insertion or deletion of chromosomes/bases that are not multiples of three that can maintain the normal reading pattern/frame.

"Discuss three factors that affect your daily food choices. For each factor with a negative outcome, suggest at least one change you could make in your daily behavior that would turn that negative outcome to a positive outcome.
Answer:
Three factors that affect my daily food choices include:
1. Taste
2. Length of time for preparation
3. Method of preparation.
Explanation:
When making choices for food, I tend to take several factors into consideration. Some of these factors include;
1. The taste of the food: If the food tastes good and is not too spicy I am more inclined to choose such food.
2. Length of time for preparation: Especially on stressful days, I tend to consider the length of time required to prepare a healthy meal. If it takes so much time I am more inclined to eat fast food which is not a good choice.
To change this negative outcome, I hope to plan my affairs for the day and prepare healthy meals beforehand, which could be stored in the refrigerator and reheated when I need it.3. Method of Preparation: Some foods require paying attention to details. For example, food that uses up, a lot of vegetables would require thorough washing to prevent particles in the food. Busy days also get me exhausted with no strength to pay attention to these protocols.
To turn this around, I hope to employ the help of a family member to make the process easier. I also hope to process most of my ingredients and keep them ready for use so that I would not have to do a lot of processing while cooking.Which environmental change is considered short term?

4. When focusing on high power, always use the coarse adjustment knob to focus.
A. True
B. False
5. A coverslip should always be used with wet mounts.
A. True
B. False
Answer:
1.false.
There are special lense tissues for this which will not scratch the lense so that the focal power will nit be affected. Grit -free lens paper,Kimwipes or Kodak lens are ideal cleaning materials.
2.This is also false. Microscope should be covered with dust cover, and even in the cabinet,It should never be left without am eyepiece.
3.True.
This gives he lowest magnification, which allows for wide view of the specimen in order get the specific spot to focus on.It has magnification power of 10x eyepiece lens.Thus a 4x scanning objective lens therefore gives total magnification of 40x.
4.False,
This will break the objective lens.Fine adjustment knob should be use.This will gives the sharpest focus,using a coarse knob will crack the lens because the working distance for focusing will be too small, and suing this will damage the objective lens,
5.False,only the wet mount should be used.High power and oil lens should not be used as this will reduce the efficiency of the microscope.

Answer:
The macromolecules; protein helps to gain muscle, fat helps provide stored energy for longer period, carbohydrates provide immediate energy.
Explanation:
Proteins are the macromolecules that help on the muscle building and storage. Bodybuilders utilize proteins to build their body and muscle protein. Protein has equal energy value as carbohydrates.
Fat help in providing energy when there is no carbohydrate provided energy to utilize. In the winters some animals hibernate they utilize the fat provided energy during the hibernation period.
Carbohydrate gives energy immediately for the cellular process and also help athletes to provide energy immediately. Runners drink carbohydrates based drinks to get energy before the race.

Explanation:
If two genes are found on different chromosomes, or if they are far enough apart on the same chromosome that the chance of a crossover between them is very high, the genes are considered to be unlinked. Unlinked genes follow Mendel’s law of independent assortment. If, however, two genes tend to "travel together" because they are near one another on the same chromosome, they are said to be linked. Linked genes do not follow Mendel’s law of independent assortment. In this tutorial, you will compare the inheritance patterns of unlinked and linked genes.
Part A - Independent assortment of three genes
A wild-type tomato plant (Plant 1) is homozygous dominant for three traits: solid leaves (MM), normal height (DD), and smooth skin (PP).
Another tomato plant (Plant 2) is homozygous recessive for the same three traits: mottled leaves (mm), dwarf height (dd), and peach skin (pp)
Leaves Height Fruit Plant 1 solid normal Smooth (PP) (MM) (DD) Plant 2 mottled (mm) dwarf peach (Pp) (dd)
In a cross between these two plants (ADOPPx mmddpp), all offspring in the F, generasion are wild type and heterozygous for all three traits (AmDdPp)
Now suppose you perform a testcross on one of the F, plants (mOoPpx mmodpp). The F, generation can include piants with these eight possible phanotypes
a) solid normal, smooth
b) solid norma peach
c) solid dwarf smoom
d) solid dvarf, peach
a) motted nomal, amooth
b) motted, normal pesch
c) mottied, dwad smooth
d) moted dwaf peach
Assuming that the three genes undergo independent assortment, predict the phenotypio ratio of the offspring in the F, generation.
Complete question:
A wild-type tomato plant (Plant 1) is homozygous dominant for three traits: solid leaves (MM), normal height (DD), and smooth skin (PP).
Another tomato plant (Plant 2) is homozygous recessive for the same three traits: mottled leaves (mm), dwarf height(dd), and peach skin (pp).
In a cross between these two plants (MMDDPP x mmddpp), all offspring in the F1 generation are wild type and heterozygous for all three traits(MmDdPp).
Now suppose you perform a testcross on one of the F1plants (MmDdPp x mmddpp). The F2 generation can include plants with these eight possible phenotypes:
solid, normal, smooth
solid, normal, peach
solid, dwarf, smooth
solid, dwarf, peach
mottled, normal, smooth
mottled, normal, peach
mottled, dwarf, smooth
mottled, dwarf, peach
Assuming that the three genes undergo independent assortment, predict the phenotypic ratio of the offspring in the F2 generation.

F2) 8/64 = 1/8 MmDdPp, solid leaves, normal height, smooth skin
8/64 = 1/8 MmddPp, solid leaves, dwarf height, smooth skin
8/64 = 1/8 MmDdpp, solid leaves, normal height, peach skin
8/64 = 1/8 Mmddpp, solid leaves, dwarf height, peach skin
8/64 = 1/8 mmDdPp, mottled leaves, normal height, smooth skin
8/64 = 1/8 mmddPp, mottled leaves, dwarf height, smooth skin
8/64 = 1/8 mmDdpp, mottled leaves, normal height, peach skin
8/64 = 1/8 mmddpp, mottled leaves, dwarf height, peach skin
Another way of predicting the phenotypic ratio of the offspring in the F2 generation is by performing a testcross for each gene by separately and then multiplying their genotypic proportions. This is:
Leaves Gene
Parental) Mm x mm
Gamtes) M m m m
Punnet Square) M m
m Mm mm
m Mm mm
F2) 1/2 Mm
1/2 mm

Parental) Dd x dd
Gamtes) D d d d

F2) 1/2 Dd
1/2 dd
Skin Gene
Parental) Pp x pp
Gamtes) P p p p
Punnet Square) P p
p Pp pp
p Pp pp
F2) 1/2 Pp
1/2 pp
To get the phenotypic ratio of the offspring we multiply the genotypic proportion for each trait by the genotypic proportions of the other two traits, like this:
For plants with solid leaves, normal height, smooth skinsolid leaves ratio -> 1/2
normal height ratio -> 1/2
smooth skin ratio -> 1/2
MmDdPp ratio: 1/2 x 1/2 x 1/2 = 1/8
For plants with solid leaves, dwarf height, smooth skinMmddPp ratio: 1/2 x 1/2 x 1/2 x 1/2 = 1/8
For plants with solid leaves, normal height, peach skinMmDdpp ratio: 1/2 x 1/2 x 1/2 x 1/2 = 1/8
For plants with solid leaves, dwarf height, peach skinMmddpp ratio: 1/2 x 1/2 x 1/2 x 1/2 = 1/8
For plants with mottled leaves, normal height, smooth skinmmDdPp ratio: 1/2 x 1/2 x 1/2 x 1/2 = 1/8
For plants with mottled leaves, dwarf height, smooth skinmmddPp ratio: 1/2 x 1/2 x 1/2 x 1/2 = 1/8
For plants with mottled leaves, normal height, peach skinmmDdpp ratio: 1/2 x 1/2 x 1/2 x 1/2 = 1/8
For plants with mottled leaves, dwarf height, peach skinmmddpp ratio: 1/2 x 1/2 x 1/2 x 1/2 = 1/8
Why do processes and activities suddenly change the global temperature?
Answer:
hey mate here is your answer
Answer:
Earth's temperature depends on the balance between energy entering and leaving the planet’s system. When incoming energy from the sun is absorbed by the Earth system, Earth warms. When the sun’s energy is reflected back into space, Earth avoids warming. When absorbed energy is released back into space, Earth cools. Many factors, both natural and human, can cause changes in Earth’s energy balance, including:
Explanation:
Variations in the sun's energy reaching Earth
Changes in the reflectivity of Earth’s atmosphere and surface
Changes in the greenhouse effect, which affects the amount of heat retained by Earth’s atmosphere
