Explain why it is necessary that gametes (egg cells and sperm cells) have half the DNA that normal body cells have.​

Answers

Answer 1

Answer:Gametes are reproductive cells, such as sperm and egg. As gametes are produced, the number of chromosomes must be reduced by half. Why? The zygote must contain genetic information from the mother and from the father, so the gametes must contain half of the chromosomes found in normal body cells.

The race is now in earnest. How do the ""discoverers"" come to their conclusion about the structure of DNA? What information did they need?

Answers

They needed the general helix structure and the symmetry 15.

The information needed by them is about its helix structure.

DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.Each molecule of DNA is a double helix formed from two complementary strands of nucleotides held together by hydrogen bonds between G-C and A-T base pairs. Duplication of the genetic information occurs by the use of one DNA strand as a template for formation of a complementary strand.

Peter, who lived 200 years ago, had a house with no rats in it. One day, his wife
heard some scurrying around on his straw roof. He went up and guess what he
found? A rat's nest. Peter was really smart--where did he think the new rats came
from? Well 200 years ago, people believed that part of the straw roof somehow
turned into rats. Why would Peter, even though he was very intelligent, accept this
idea?
We're all really smart, but its not like we're the smartest people in the world. We all know that it takes a momma rat and daddy rat to make some baby rats.
This is because we understand something called the cell theory, because the cell theory is just part of our culture now. It's something a lot of our behaviors and
other ideas are based.
1. All living things are made of cells
2. Cells come from other cells
3. Cells are the smallest unit of life

1. Using two parts of the cell theory, explain to Peter why these two parts show
that the straw roof did not turn into the rats.
2. What do we mean when we say 'The cell is the smallest unit of life? Explain as if
you were talking to Peter, who has no idea about cells.

Answers

Answer:

1 is always rifht

Explanation:

i think so

All living things are made of cells  and Cells come from other cells are the two parts of the cell theory.

These two statements are used to show to peter about the presence of rats in the straw roof. The straw roof did not turn into the rats because straw is a non-living whereas rats are living. Rats increases its population when the male rate mate with the female rate produces baby rats.All living organisms has the ability of reproduction through sexual and asexual.The cell is the smallest unit of life' from this statement we mean that the body of all living organisms are made up of cells just like a building which is made up of bricks so we can say that this example is enough for the Peter to understand the statement about cells.

Answer:

I'm thinking maybe B, illustrates the principle of natural selection.

Explanation:

This example shows that, once a particular event happens in a species' ecosystem that negatively affects their lifestyle, natural selection occurs and kills off those with a disadvantageous adaptation (in this case the narrow-beaked finches, since they could no longer eat insects but did not have the beak size to crack seeds), allowing those with the advantageous adaptation (in this case, the thicker-beaked birds) to prosper.

If the amount if algae in the ocean decreases by 50% the population of its consumers, goby fish will?
A. Go extinct
B. Decrease to its carrying capacity
C. Increase by 50%
D. Increase to its carrying capacity

Answers

Answer:

B. Decrease to its carrying capacity

Explanation:

Goby fish feed over algae for their survival and growth but if 50% of algae in the ocean decreases then the population of goby fish will decrease to its carrying capacity.

This is so because then the goby fish will be dependent on the left number of algae and maximum population size will depend on the rest 50% of food or algae available.

Hence, the correct answer is "B. Decrease to its carrying capacity".

Consumers in the food chain do not produce their food and depends on the producers ( plants, algae and plankton ) which produce foods with the use of energy and gaseous carbon dioxide.

some of the types of cells found in  consumers are :

Muscle cells : these are cells that make up the muscles found in consumers that e.g. skeletal and cardiac muscle cellsNerve cells : these cells are responsible for relaying impulses messages to and from the brain found in consumers Bone cells : cells making of the bones and they are of three types : osteoblasts, osteocytes, osteoclasts.

Consumers depend on the primary producers for their source of calories, consumers are more complex than producers in their composition hence the type of cells that they contain includes : Muscle cells, Nerve cells and Bone cells.

Hence we can conclude that the type of cells consumers would contain are : Muscle cells , Nerve cells and Bone cells.
