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.

Plants take in carbon dioxide from the atmosphere.
Figure 2 shows part of the carbon cycle.
Describe how carbon from the atmosphere is cycled through living organisms.
Answer:
Carbon enters the atmosphere as carbon dioxide from respiration and combustion. Carbon dioxide is absorbed by producers to make glucose in photosynthesis. ... Decomposers break down the dead organisms and return the carbon in their bodies to the atmosphere as carbon dioxide by respiration.

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.

What is artificial selection? How is the development of different dog breeds an illustration of artificial selection?
Answer:
Artificial selection is process in which humans select the traits in animals and plants and use animal breeding or plant breeding to produce the animal or plants with desired traits.
Different dog breeds is very good example of artificial selection because with the help of artificial selection humans can drastically alter the appearance of dogs. With artificial selection human can develop Great Dane from the tiny Chihuahua.

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.

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.

Terrence likes to eat morel mushrooms, which are native to Georgia. How do the kingdoms to which humans and morels belong DIFFER? How are they SIMILAR?
Answer:
Mushrooms are in kingdom Fungi and humans are in kingdom Animalia
Explanation:
These two kingdoms are similar in that they are both in Domain Eukarya, meaning they have eukaryotic cells (have a nucleus, membrane bound organelles, are relatively large and organized). Both are also heterotrophic, meaning they eat other organisms to get energy. They are different in that fungi cells have cell walls made of chitin while animals do not have cell walls. Fungi tend to live pretty sedentary lives, and while that is true for some animals, that is not true of most. Fungi are also decomposers while animals are consumers.

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.

A student wanted to see if covering a leaf in foil would stop it from producing starch. Why should the student put the plant in a dark cupboard for 48 hours before returning it to the light and starting the experiment?
1. To make the results reliable
2. So that the plant would photosynthesise faster when returned to the light
3. So that any starch already in the leaf was used up by the plant
4. He did that simply
Answer:
4.) He did that simply
Explanation:
I'm just guessing it's 1 because the other answers don't seem reasonable
Answer:
Putting the plant in dark for 48 hours would stop the process of photosynthesis as light is required for it. Photosynthesis produces organic sugars which are stored in form of starch in plants. The absence of photosynthesis would lead to the consumption of all stored starch making the leaf starchless. The correct answer is option D.
