Explanation:
White tailed deer begin their reproductive cycle in the fall. Rising testosterone levels in
male white tailed deer cause them to start their breeding season around the same
time. Offspring are born the following spring and summer.
What is the most likely explanation for the white-tailed deer having a seasonal
breeding cycle instead of a monthly breeding cycle?
The explanation for the white-tailed deer having a seasonal breeding cycle should be that deer provide birth in the spring and summer.
What is seasonal breeding?It is considered to be animal species so it should be successfully mated at the time of specific times of the year. It permits the optimization of survival of young because of factors like food, water availability, etc
So, here deer provide birth in the spring and summer for avoiding the pregnancy at the time of hot summer months.

who adapts, the population or individual
Answer:
to be honest i think the answer is the population
Explanation:
Answer:
Populations evolve through a process known as natural selection which allows individuals with beneficial traits for survival to breeding with other individuals who share those traits, eventually leading to offspring who only exhibit those superior traits.

Please correct me if I am wrong for the third one
Answer:
1. Hypotonic
2.Isotonic
3.Hypertonic
Explanation:
Number 1 is hypo tonic because solute is going into the cell. The cell is getting bigger and expanding. You can think of Hypotonic as getting bigger by using Hypo which can be Hippo. Hippos grow bigger over time.
Number 2 is Isotonic. The water is going in and out at the same rate. Therefore, nothing really changes here.
Number 3 is Hypertonic because the cell has shrunk.
Q.19. During which period did the first flowering plants (angiosperms) appear?
a) Triassic
b) Silurian
C) Jurassic
d) Cretaceous
Answer:
Cretaceous
Explanation:
They began changing the way the world looked almost as soon as they appeared on Earth about 130 million years ago, during the Cretaceous period. That's relatively recent in geologic time: If all Earth's history were compressed into an hour, flowering plants would exist for only the last 90 seconds
Why is it so important for us to decrease our use of fossil fuels?
A. The combustion of fossil fuels are causing a hole in the Ozone layer
B. The combustion of fossil fuels leads to an increase in atmospheric CO2 which leads to global climate change
C. The combustion of fossil fuels help us meet our energy demands, so it is not that important that we switch to alternatives.
D. Fossil Fuels do not harm the environment, but we are running out of them so we need alternatives.
help me please please
Answer: it
Explanation: I know
Answer:
B.
Explanation:
Fossil fuels definitely harm the environment, and their supply is depleting. So that takes out answers C and D, leaving A and B. The main cause of ozone depletion and the ozone hole is manufactured chemicals being released into the air. While CO2 from fossil fuels does have an effect on worsening the hole, it has a much higher effect on global climate change.

"Crossing Over" occurs in Prophase 1 of Meiosis.
True
False
Answer:
true
Explanation:
Answer:
Crossing over occurs during prophase I of meiosis before tetrads are aligned along the equator in metaphase I. By meiosis II, only sister chromatids remain and homologous chromosomes have been moved to separate cells. Recall that the point of crossing over is to increase genetic diversity.

Write a 2 paragraph summary about the structure of DNA from the information on the first page.
FYI the picture is attached
Answer:
DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases. To form a strand of DNA, nucleotides are linked into chains, with the phosphate and sugar groups alternating.
The four types of nitrogen bases found in nucleotides are: adenine (A), thymine (T), guanine (G) and cytosine (C). The order, or sequence, of these bases determines what biological instructions are contained in a strand of DNA. For example, the sequence ATCGTT might instruct for blue eyes, while ATCGCT might instruct for brown. The complete DNA instruction book, or genome, for a human contains about 3 billion bases and about 20,000 genes on 23 pairs of chromosomes.

Which of the following is the complimentary DNA strand for the sequence shown below?
ACT GCA
Please explain, if possible.
The complimentary DNA strand for the sequence ACT GCA is TGA CGT.
What is DNA?DNA stands for deoxyribonucleic acid which is defined as a polymer made up of two polynucleotide chains which coil around each other to form a double helix.
Primarily DNA is located in the cell nucleus called nuclear DNA, but a small amount of DNA can also be found in mitochondria called mitochondrial DNA or mtDNA, so mitochondria are structures within cells that store energy from food that converts into energy.
The information in DNA is stored in the form of code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T) which are bond to each other by hydrogen bond like A with T with 2 hydrogen bonds while C with G with 3 hydrogen bonds. Like for above given information, ACT GCA complimentary strand is TGA CGT
Thus, The complimentary DNA strand for the sequence ACT GCA is TGA CGT.

Which nitrogenous base would pair with adenine during DNA replication?
A
O cytosine
<
B
O guanine
C
Othymine
D
ouracil
The nitrogenous base would pair with adenine during DNA replication is othymine. Thus, option C is correct.
What are nitrogenous base?
Replication relies on complementary base pairing, that is the principle explained by Chargaff's rules and adenine (A) always bonds with thymine (T) and cytosine (C) always bonds with guanine (G). 18% became cytosine pairs with G. A pairs with T. T and C are not complementary base pairs, but we know that if molecules consists of 32% T, it must have 32%.
The discovery of the structure of DNA was useful because it revealed how mRNA was used to make proteins. There are four nitrogen bases of DNA nucleotides are such as adinine, thymine, guanine and cytosine.
HDL stands for high-density lipoprotein or good cholesterol which absord cholesterol and send it to lever. The lever then flushes it from the body. High-density lipoprotein can lower your risk for heart disease and stroke.
Therefore, The nitrogenous base would pair with adenine during DNA replication is othymine. Thus, option C is correct.

Which of the following statement is true about fossil ?
Answer:
there are no statements...
Explanation:
Answer:
Explanation:The deeper you go into the Earth the older the fossils will be. So, in the diagram you have provided we see that fossil #5 is the oldest and fossil #2 is the youngest.
The order of age goes like this (from youngest to oldest):
1. Fossil #2
2. Fossil #1
3. Fossil #4
4. Fossil #3
5. Fossil #5
Therefore, the only correct answer would be that fossil #4 is younger than fossil #3.
Choose the correct statements 1.Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. 2.Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species. 3cross-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. 4.Self-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species.
Answer: The correct statements are 1 and 2:
1.Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant.
2.Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species.
Explanation:
Pollination is the transfer of pollen grains from an anthers to a receptive stigma. In most species of flowering plants, external agents bring about pollination. Also, flowers have evolved special structures and mechanisms to ensure successful pollination.
There are two types of pollination
--> Self pollination: This takes place when mature pollen grains from the anther of a flower fall on the stigma of the same flower or that of another flower on the same plant. This type of pollination brings the male gametes and egg cells of the same plant together. The resultant offspring show very little genetic variation.
--> Cross pollination: This occurs when mature pollen grains of a flower are transferred to the stigma of a flower of another plant of the same or closely related species. This brings the male gametes and egg cells of two different parent plants together. Therefore, there is greater genetic variation among the offspring.
