Answer:
True. The atmosphere protects life on earth by shielding it from incoming ultraviolet (UV) radiation, keeping the planet warm through insulation, and preventing extremes between day and night temperatures.Greenhouse gases, such as carbon dioxide, methane, nitrous oxide, and certain synthetic chemicals, trap some of the Earth's outgoing energy, thus retaining heat in the atmosphere.
The statement is true.
Effect of atmosphere on climateAtmosphere of earth contains oxygen which we use for breathing. The gases present in the atmosphere such as ozone protects us from harmful ultraviolet solar radiation.
It creates the pressure without which liquid water couldn't exist on our planet's surface. The greenhouse gases warms our planet and keeps temperatures habitable for our living Earth.

Goats and sheep belong to the same family but different genera. While they often live together in the same pastures, the hybrid offspring that are occasionally produced between the two species rarely survive. When such a hybrid does survive, it is usually sterile. Which of the following best explains the mechanism that maintains reproductive isolation between goats and sheep?
a. Gene flow is prevented because the two species belong to different trophic levels and therefore do not share a food source.
b. Habitat isolation creates a prezygotic barrier between the two species.
c. The males of one species and the females of the other species are fertile at different times.
d. The two species have a different number of chromosomes, resulting in a postzygotic barrier.
Answer:
d. The two species have a different number of chromosomes, resulting in a postzygotic barrier.
Explanation:
The two species i.e. sheep and goat have different number of chromosomes that resulting in a postzygotic barrier. Sheep has 56 number of chromosomes whereas goat has 60 number of chromosomes that causes postzygotic barrier in the offspring produced from the fusion of these two species. Postzygotic barrier leads to the creation of a hybrid that is sterile and unable to produce offspring because of difference in chromosome number.

in the fermentation experiment using yeast with the different sugars what was the dependent variable
Answer:
The dependent variable is fermentation rate.
Explanation:
When finding dependent variable phrase it like this:
______ depends on _____.
Where the first blank is the dependent variable and the second blank is the independent variable. For example, if I were to test the effects of pH on an enzyme, I would say the function of the enzyme depends on the pH level. This makes the function of the enzyme the dependent variable. In this case, fermentation rate depends on the different sugars. Hope this helps!
There was a study made in a UK forest in where it was calculated the population of red squirrels and grey squirrels. There was a clear competition and by the end of the study, there were only grey squirrels. How the decline of the red squirrel population might affect its native ecosystem??
Answer:
Predators might die out
Explanation:
Since grey squirrels can Camouflage... predators may not eat because the red squirrels die out. And grey squirrels may reproduce more because there is no competition anymore.

The passage indicates that compared with other functions of coloration in plants, camouflage in plants has A) provided scientists with a deeper understanding of potential food sources. B) made use of a wider variety of distinctive shades of colors. C) proved to be a less effective defense against predators. D) been the subject of a smaller number of scientific investigations.
Question passage: This PASSAGE is adapted from “Rare Woodland Plant Uses‘Cryptic Coloration’ to Hide from Predators.” ©2009 byAmerican Journal of Botany, Inc.It is well known that some animal species usecamouflage to hide from predators. Individuals thatare able to blend in to their surroundings and avoidbeing eaten are able to survive longer, reproduce, andthus increase their fitness (pass along their genes tothe next generation) compared to those who standout more. This may seem like a good strategy, andfairly common in the animal kingdom, but who everheard of a plant doing the same thing?In plants, the use of coloration or pigmentation asa vital component of acquiring food (e.g.,photosynthesis) or as a means of attractingpollinators (e.g., flowers) has been well studied.However, variation in pigmentation as a means ofescaping predation has received little attention.Matthew Klooster from Harvard University andcolleagues empirically investigated whether the driedbracts (specialized leaves) on a rare woodland plant,Monotropsis odorata, might serve a similar purposeas the stripes on a tiger or the grey coloration of thewings of the peppered moth: namely, to hide.
The PASSAGE indicates that compared with other functions of coloration in plants, camouflage in plants has A) provided scientists with a deeper understanding of potential food sources. B) made use of a wider variety of distinctive shades of colors. C) proved to be a less effective defense against predators. D) been the subject of a smaller number of scientific investigations.
Answer: The correct option is C(proved to be a less effective defense against predators).
Explanation:
Adaptation is a means by which plants or animals modify their forms, structures, functions and behaviour in order to escape being harmed and survive in their environment. The special adaptations of organisms in a habitat enables them to live there successfully and reproduce. There are 3 types of adaptation which include:
--> structural adaptation,
--> adaptive coloration and
--> behavioural adaptations.
From the passage, the plant under study shows ADAPTIVE COLOURATION. Colour and colour pattern plays an important role in adaptations of plants. These occur due to the presence of pigments in cells of plants. Common pigments responsible for coloration in plants are:
--> chlorophyll: this gives green colour to plants that has chloroplasts in their cells.
--> Carotene and xanthophyll: this gives yellow to orange colour to plants that has chromoplasts in their cells.
From the passage, the use of coloration or pigmentation in the plant as a vital component of acquiring food (e.g.,photosynthesis) or as a means of attracting pollinators (e.g., flowers) has been well studied but it's use to escape from predation has received little attention. Therefore camouflage in plants has proved to be a less effective defense against predators.

Although bipedalism is unusual, humans are not the only living bipeds. For example, some flightless birds are also bipedal. Identify a living nonprimate animal that is also a biped. Then, compare its bipedalism to our biped-alism.
Answer:
Explanation:
Human and birds as the basis for comparison. Some birds walk and run with their backs and femurs tilting at small angles to the horizontal and with bent knees while most human walk uprightly with legs straight and this can be seen in the duty and task performed by man.
Humans exert on the ground while walking two-peaked pattern of force which makes some human work very fast but Birds do not exact two-peaked pattern of force.
Human walking for individual with same body mass is relatively economical of metabolic energy while Bipedal locomotion is economical for wading birds, it is expensive for geese and penguins.
Only a very few flowering plants have been able to invade the oceans. But the few marine ones are very successful. What are some reasons for the small number of marine flowering plants
Answer:
1. High osmotic pressure due to the hypersaline nature of marine habitats
2. The dependence of flowering plants on pollinating insects for fertilization. These insect pollinators are however, absent in the marine environment.
3. Competition from already-established sea weeds and grasses provides another challenge to flowering plants invadingnthe oceans.
4. Constant changes in the environment as well as temperature changes too
Explanation:
The marine environment is a hypersaline environment with a high salt concentration relative to that of the plant cell. Due to high salt concentration of the marine environment, their is high osmotic pressure on living oragnisms found therein. Organisms must have well-adapted osmo-regulatory mechanisms to counteract the high osmotic pressure of their environment. Therefore, flowering plants face the challenge of removing excess salt from their cells or else lose water to their environment, hence resulting in the death of the plant. However, most flowering plants lack this ability and thus, have found it difficult to invade the oceans.
Flowering plants depends on insect-pollinators for fertilization. However, these insect are not found in the oceans, and as such, it is difficult for flowering plants to invade the oceans.
Well-adapted seaweeds and grasses serve as competitors for any invading flowering plant. Since the flowering plants are not yet adapted for life in marine habitats, they lose out in this competition.
The oceans are constantly in a state of frequent turbulence and change due to tides and currents. Also, the temperature of the oceans are very low and fluctuations in the temperatures of the ocean do occur, utimately serving as obstacles to invading flowering plants to adapt to life in the oceans and seas.

What term is used to describe the number of chromosomes in a gamete, such as
an egg cell or a sperm cell?
Answer:
The biology term, haploid can also refer to the number of chromosomes in egg or sperm cells, which are also called gametes
The term used to describe the number of chromosomes in a gamete would be haploid.
Gametes are usually formed by meiosis and meiosis is referred to as reductional division. When a normal diploid (2n) cell divides by meiosis, the daughter cells would have half the number of chromosomes of the parent cell. In other words, the daughter cells will have n number of chromosomes as opposed to 2n.
Cells with n chromosome numbers are generally referred to as haploid while those with normal 2n chromosome numbers are said to be diploid. Egg and sperm cells are haploid cells.

Explanation:
In fruit flies, the phenotype for eye color is determined by a certain locus. E indicates the dominant allele and e indicates the recessive allele. The cross between a male wild-type fruit fly and a female white-eyed fruit fly produced the following offspring.
Wild Type Male Wild Type Female White-eyed Male White-eyed Female Brown-eyed Female
F1 Generation 0 45 55 0 1
The wild-type and white-eyed individuals from the F1 generation were then crossed to produce the following offspring.
Wild Type Male Wild Type Female White-eyed Male White-eyed Female Brown-eyed Female
F2 Generation 23 31 22 24 0
Required:
a. Determine the genotypes of the original parents (P generation) and explain your reasoning.
b. Use a Chi-squared test on the F2 generation data to analyze your prediction of the parental genotypes.
Answer:
The genotypes of the original parents are
Male: X⁺Y Female: X⁻X⁻The Chi-square analysis leads us to accept the prediction of the parental genotypes.
Explanation:
Due to technical problems, you will find the complete explanation in the attached files.
(a) The genotypes for the original parents (P generation) are
Male: X⁺Y
Female: X⁻X⁻
(b) The prediction of the parental genotype is accepted by the Chi-squared test analysis.
What is the eye color pattern in fruit flies?Drosophila Melanogaster is a fruit fly with abnormally big, brightly colored eyes.
The range in color from red to sepia to white reveals a lot about the genetic makeup of the fly.
(a) E = + ⇒ Dominant allele coding for wild-type eyes
e = - ⇒ Recessive allele coding for white eyes
Now, Crossing the : male wild-type with a female white-eyed
(Parental) = X⁺Y x X⁻X⁻
(Phenotype) = wild white
(Gametes) = X⁺ Y X⁻ X⁻
(Punnett square) = X⁺ Y
X⁻ = X⁺X⁻ X⁻Y
X⁻ = X⁺X⁻ X⁻Y
In (F1)generation = 2/4 = 1/2 = 50% of the progeny are expected to be wild-type females.
And 2/4 = 1/2 = 50% of the progeny are expected to be white-eyed males.
Thus, the percentages are almost 50:50, as the expected ones.
So, the genotypes of the original parents are
Male: X⁺Y
Female: X⁻X⁻
(b) Using Chi-squared test :
Observed fruit fly type:
Wild Type Male - 25
Wild Type Female - 31
White-eyed Male - 22
White-eyed Female - 24
Expected fruit fly type:
Wild Type Male - 25
Wild Type Female - 25
White-eyed Male - 25
White-eyed Female - 25
Now, chi square [tex]= \sum\dfrac{(O- E)^2 }{E}[/tex]
By putting numbers in the formula, we are getting
Wild Type Male - 0.16
Wild Type Female - 1.44
White-eyed Male - 0.36
White-eyed Female - 0.04
Now, X² = 0.16 + 1.44 + 0.36 + 0.04 = 2
Critical value = 7.82
X² (2) < critical value (7.82)
Thus, this is the evidence to accept the given hypothesis.

The budding of clathrin-coated vesicles from eukaryotic plasma membrane fragments can be observed when adaptations, clathrin, and dynamin-GTP are added to the membrane preparation. What would you observe if you omitted (A) adaptations, (B) clathrin, or (C) dynamin
Answer:
Explanation:
Adaptins:
Adaptor proteins, which attach the clathrin to the membrane, are required for clathrin-coated vesicles to form. Clathrin cages form in solution at strong clathrin concentrations and under the right ionic environments and parameters, but they are empty hollow shells without membranes or other proteins. The data for clathrin baskets are included in the clathrin molecules themselves, as shown by the self-assembly of clathrin into baskets. Clathrin coat cannot form or build up without adjusting to the membrane it is attached to.
Clathrin:
Adaptins bind and act synergistically to specific receptors without clathrin, but no vesicles or clathrin are formed. There exists coated pits formations, but no clathrin coat.
Dynamin:
Clathrin-coated pits can develop and progress toward vesicle formation in the exclusion of dynamin, but the final step, known as membrane fusion, is inhibited. Consequently, in the exclusion of dynamin, strongly invaginated covered pits will be noticed. As a result, vesicles are unable to pinch the membrane.
Suppose plasma membrane fragments were prokaryotic cells, there would be no endocytosis and hence no adaptin or coatings. Endocytosis is not performed by prokaryotic cells. There are no receptors with adequate cytosolic tails in a prokaryotic cell that might facilitate the binding to adaptor proteins. As a result. no clathrin-coated vesicles will develop.
