A. Transporting eggs
B. Developing a fetus
C. Storing eggs
D. Collecting sperm
Answer:Your answer for this question is D.
Explanation:
The purpose of the part of the female reproductive system highlighted is to collect sperm; that is the last option (D), and after that, the sperm go to the female fallopian tube.
What is the female reproductive system?The female reproductive system is a complex network of organs and structures that work together to produce, transport, and fertilize an egg, as well as support the growth and development of a fetus during pregnancy. The primary organs of the female reproductive system are the ovaries, which produce and release eggs, and the uterus, which is the muscular organ where a fertilized egg implants and develops into a fetus.
Hence, the purpose of the part of the female reproductive system highlighted is to collect sperm; that is the last option (D), and after that, the sperm go to the female fallopian tube.

Answer:
1 .Atom goes to C
2.Proton goes to A
3. Neutron goes to b
Question 4:Protons are a type of subatomic particle with a positive charge. ... Protons and neutrons have approximately the same mass, but they are both much more massive than electrons (approximately 2,000 times as massive as an electron). The positive charge on a proton is equal in magnitude to the negative charge on an electron
Question 5:Atoms are the basic building blocks of ordinary matter. Atoms can join together to form molecules, which in turn form most of the objects around you. ... The protons and neutrons cluster together in the central part of the atom, called the nucleus, and the electrons 'orbit' the nucleus.
Question6:Thomson's model of the atom in 1897 shows that the atom was a sphere of matter, wherein the electrons are mixed inside it. This model does not show the protons and the neurons. On the contrary, the current model that was proposed by Niels Bohr gives us a clearer representation of the structure of an atom.

A red blood cell has a salt concentration of 0.9%. What will happen if it is placed into
a 0.8% salt solution? The red blood cell will
burst
remain the same
shrink then grow
shrink
Answer:
Shrink
Explanation:
The blood cell would shrink because of osmosis. The molecules move with the concentration gradient so water molecules will move outside of the cell where there is less water than inside of the cell.
Blood cells are the main constituents of the circulatory system and carry the most vital function of oxygen transportation. Blood cells have a specific concentration and osmotic pressure to remain vital.
The correct answer is:
Option D. Shrink.
This can be explained as:
Cells have a tendency to shrink in hypertonic solutions while swells in hypotonic solutions.0.8% of the salt solution will act as a hypertonic solution and the RBC placed in it will shrink.When cells are placed in hypertonic solution it loses their water content to the outside surface and hence shrink.Therefore when the red blood cells are placed in 0.8% salt solution they will shrink.

Molecule X is most likely what kind of compound/molecule? *
Molecule X is an enzyme to which the starch is bonded and starch- enzyme complex is formed.
What is an enzyme?An enzyme is a type of protein that acts as a catalytic agent in chemical reactions. Enzymes play a crucial role in metabolism and other biological processes by increasing the rate at which chemical reactions occur.
Enzymes work by lowering the activation energy needed for a reaction to take place. In other words, enzymes make it easier for the reactants in a chemical reaction to come together and form products. This is accomplished by the enzyme binding to one or more of the reactants, known as substrates, and bringing them into a specific orientation that promotes the reaction. Once the reaction has taken place, the enzyme is free to bind to another set of substrates and catalyze the reaction again.
Enzymes are highly specific, meaning that each enzyme typically catalyzes only one particular reaction or a small group of closely related reactions. They are also highly efficient, able to catalyze millions of reactions per second.

explain why it is an advantage for plants to store carbohydrates as starch rather than as sugars
Answer:
More energy are packed into less space by starch molecules far more than glucose or sucrose yet they are able to release this energy easily, hence maximizing both storage and mobilization.
Explanation:
When plants have a period of dormancy to survive, they store their food as starch. They store enough of this energy so as to be able to restart with and to be able to maintain metabolism for the entire period of dormancy.
In addition, we know that starch is not water soluble, hence, lacks the ability to pull water into storage cells or cause irregularity in water balance. More energy are packed into less space by starch molecules far more than glucose or sucrose yet they are able to release this energy easily, hence maximizing both storage and mobilization.
Glucose is not directly transported by plants to storage. Rather, in a plant stem, the form of carbohydrate being transported is sucrose and this is because it is a non-reducing and does not react with oxygen during transport in the stem to specialized storage plastids.
It is advantageous for plants to store carbohydrates as starch rather than as sugars because:
sugars such as sucrose, fructose, and glucose are soluble and cannot be stored in the body of plant.as such, plants have to find a way to store their food reservesone way to store the food would be to store them in less soluble form that cannot be washed away easily and can also be converted to usable forms when needed.Hence, starch provides for that option. Cellulose could also have been a choice, but its structure makes it such that it becomes a permanent part of the plant and cannot be converted to usable food anymore.Hence, it is advantageous to store carbohydrates as starch by plant rather than sugars because starch cannot be washed away easily and can also be converted to usable foods when needed.

why do we commonly see isotherms on local weather broadcasts?
Explanation:
Isotherms are lines of constant or equal temperature. They are often used on weather maps by meteorologists to give a large scale view of temperatures across the U.S. If you have ever looked at a weather map in a newspaper, the isotherms are used to divide the color-filled temperatures.
Read the following passage and construct a flow chart:
Exercise begins with skeletal muscle contraction, an active process that requires adenosine triphosphate (ATP) for energy. A small amount of ATP is present in the muscle when contraction begins. This ATP can be used and replenished to fuel about 15 seconds of intense exercise, after which point the muscle must generate more ATP through the process of cellular respiration. During cellular respiration, oxygen is used up when it combines with hydrogen to form water (oxidative phosphorylation). Thus, as a muscle's metabolism increases during exercise, the concentration of oxygen in the tissue decreases, while temperature, acid, and CO2 increase. These factors and the homeostatic sensors that detect them send out signals that result in local vasodilation, which shunts bloodflow from inactive tissues to the exercising muscles, where it is needed.
Drag and drop each of the following terms to form a flow chart.
Person starts to exercise
Oxygen sensors cause local blood cell vessels to dilate
Skeletal muscle metabolism increase
Skeletal muscle oxygen demand increase
Blood delivery to the skeletal muscle increases is order to provide more oxygen
Solution :
A flowchart may be defined as the diagram which represents the process or the workflow of any process. It is the step by step approach to solve or to do the process.
In the context, the the sequence of each of the terms to form a flowchart is :
1. Person starts exercising.
2. The metabolism of the skeletal muscle increases.
3. The demand for oxygen for the skeletal muscle increases.
4. The oxygen sensors causes the local blood cell vessels to dilate.
5. For providing more of oxygen, the blood flow to the skeletal muscle increases.
In the tomato, three genes are linked on the same chromosome. Tall is dominant to dwarf, skin that is smooth is dominant to skin that is peachy, and fruit with a normal tomato shape is dominant to oblate shape. A plant that is true-breeding for the dominant traits was crossed to a dwarf plant with peachy skin and oblate fruit. The F1 plants were then testcrossed to dwarf plants with peachy skin and oblate fruit. The following results were obtained:151 tall, smooth, normal33 tall, smooth, oblate11 tall, peach, oblate2 tall, peach, normal155 dwarf, peach, oblate29 dwarf, peach, normal12 dwarf, smooth, normal0 dwarf, smooth, oblateConstruct a genetic map that describes the order of these three genes and the distances between them.
Answer:
Genetic Map + distances between genes
---T--------------S---------------N---
║---6.4%---║----16.3%---║
║-----------22.7%-----------║
Explanation:
Available data:
three diallelic genes are linked on the same chromosome: T gene codifies for height, S gene codifies for skin texture, and N gene codifies for fruit shape.Tall (T-) is dominant to dwarf (tt)Skin that is smooth (S-) is dominant to skin that is peachy (ss)Fruit with a normal tomato shape (N-) is dominant to oblate shape (nn)A plant that is true-breeding for the dominant traits was crossed to a dwarf plant with peachy skin and oblate fruitF1 plants were then testcrossed F2: 151 tall, smooth, normal T-S-N-33 tall, smooth, oblate T-S-nn11 tall, peach, oblate T-ssN-2 tall, peach, normal T-ssnn155 dwarf, peach, oblate ttssnn29 dwarf, peach, normal ttssN-12 dwarf, smooth, normal ttS-N-0 dwarf, smooth, oblate ttS-nnWe can recognize the parental gametes in the descendants because their phenotypes are the most frequent,
151 tall, smooth, normal TSN155 dwarf, peach, oblate tsnwhile the double recombinants are the less frequent.
2 tall, peach, normal TsN0 dwarf, smooth, oblate tSnAnd simple recombinant gametes produced by the cross, which frequencies are intermediate.
33 tall, smooth, oblate TSn11 tall, peach, oblate Tsn29 dwarf, peach, normal tsN12 dwarf, smooth, normal tSNComparing the parental and the double recombinant we will realize that they only change in the position of the alleles S. This suggests that the position of the gene skin texture is in the middle of the other two genes, because in a double recombinant only the central gene changes position in the chromatid.
---T-----S-------N---
Now we will call Region I to the area between T and S and Region II to the area between S and N.
---T------S-------N---
RI RII
Once established the order of the genes we can calculate distances between them, and we will do it from the central gene to the genes on each side. First We will calculate the recombination frequencies, and we will do it by region. We will call P1 to the recombination frequency between T and S genes, and P2 to the recombination frequency between S and N.
P1 = (R + DR) / N
P2 = (R + DR)/ N
Where: R is the number of recombinants in each region, DR is the number of double recombinants in each region, and N is the total number of individuals. To calculate the recombination frequency, we have to know that 1% of recombinations = 1 map unit = 1cm. And that the maximum recombination frequency is always 50%.
N = 151 + 33 + 11 + 2 + 155 + 29 + 12 + 0 = 393
So:
P1 = (R + DR) / N = 2 + 0 + 11 + 12 / 393 = 0.064 P2 = (R + DR)/ N = 2 + 0 + 33 + 29 / 393 = 0.163Now, to calculate the recombination frequency between the two extreme genes, A and B, we can just perform addition or a sum:
P1 + P2= Pt
0.064 + 0.163 = Pt
0.227 = Pt
The genetic distance will result from multiplying that frequency by 100 and expressing it in map units (MU). One centiMorgan (cM) equals one map unit (MU). The map unit is the distance between the pair of genes for which one of every 100 meiotic products results in a recombinant product.
P1 = 0.064 x 100 = 6.4% P2 = 0.163 x 100 = 16.3% Pt = 0.227 x 100 = 22.7%Genetic Map

About 200 minerals make up the rocks.
What are Rocks?The chemical composition and atomic structure of minerals are distinctive. Numerous physical characteristics of minerals, including as hardness, lustre, streak, and cleavage, can be used to quickly identify them. For instance, the mineral quartz is quite hard and not as readily scratched as the mineral talc, which is quite soft and easily scratched.
One of the most effective ways to categorize and differentiate between various minerals is by careful examination of crystal forms.
A crystalline solid is composed of constituent atoms, molecules, or ions arranged in an orderly repeating pattern that extends across all three spatial dimensions.

Thanks to the field of linguistics we know much about the development of the 5,000 plus languages in existence today. We can describe their grammar and pronunciation and see how their spoken and written forms have changed over time. For example, we understand the origins of the Indo-European group of languages, which includes Norwegian, Hindi and English, and can trace them back to tribes in eastern Europe in about 3000 BC.
So, we have mapped out a great deal of the history of language, but there are still areas we know little about. Experts are beginning to look to the field of evolutionary biology to find out how the human species developed to be able to use language. So far, there are far more questions and half-theories than answers.
Find in this text 6 noun and 6 adverd and 6 adjectives and 6 noun phrase and 6 Adverbial clause
We know that human language is far more complex than that of even our nearest and most intelligent relatives like chimpanzees. We can express complex thoughts, convey subtle emotions and communicate about abstract concepts such as past and future. And we do this following a set of structural rules, known as grammar. Do only humans use an innate system of rules to govern the order of words? Perhaps not, as some research may suggest dolphins share this capability because they are able to recognise when these rules are broken.

The number of observed individuals:
Total number: 890 flies (672 + 218) Long-winged = 672 Dump-winged = 218In the F2 generation, if l was a recessive allele and L a dominant allele, exhibiting complete dominance, we would expect a 3:1 phenotypic ratio.

1 ll genotype ---------------------X = 222.5 dump-winged individuals
Chi square = ∑ (O-E)²/E
LL + Ll = (O-E)² /E
LL+ Ll = (672 - 667.5) ² / 667.5
LL + Ll = 0.03
ll= (O-E)²/E
ll= (218 - 222.5)² / 222.5
