Match the following
This diagram shows the menstrual cycle.
Explain whether the
female is pregnant.
Please explain why because I’m struggling.
Answer:
According to the hormone diagram of the menstrual cycle, the woman is not pregnant due to the behavior of progesterone and estrogens, whose levels do not increase, in addition to the absence of human chorionic gonadotropin.
Explanation:
The graph shows the behavior of hormones during a woman's menstrual cycle in the absence of pregnancy.
During a woman's normal cycle, estrogen, luteinizing hormone (LH) and follicle stimulating hormone (FSH) tend to increase prior to ovulation, reach their peak values at ovulation, and then decline, as shown in the graph. Progesterone, on the other hand, increases after ovulation and decreases if the woman does not become pregnant.
In the case of a pregnant woman:
Estrogens continue to increase after ovulation, produced by the ovaries and placenta. Progesterone also increases its levels, as it is a hormone produced by the ovaries and placenta. Hormone human chorionic gonadotropin (HCG) appears and increases during pregnancy, due to the secretory activity of the placenta.The diagram represents the normal cycle of a woman who is not pregnant.

Scientists have discovered a new type of organism. To assign the organisms to a domain and a kingdom, which of the following is MOST important for the scientist to know?
Options
A- The organisms reproductive rate
B- The organism cell structure
C-The organisms population size
D-The organism social behavior
B- The organism cell structure
Explanation:The options you can rule out:
A- The organisms’ reproductive rate isn’t important since it’s just telling how fast the organism can grow, and it doesn’t provide information on where to assign it to a domain and kingdom.
C- The organisms’ population size of the organism isn’t important since it just shows how many there are, but it doesn’t provide information on where to assign it to a domain and kingdom
D- The organisms’ social behavior can be important (since it’s talking about how the organism acts and behaves toward other organisms, but it isn’t important on where to assign it to a domain and kingdom
Hence,
If scientists discovered a new type of organism, Option B: knowing the organism cell structure is most important, because it goes in dept on what the specific formation of the organism. Looking at the cell structure provides information on what where to assign is to a domain and kingdom.

A cleft chin is a dominant trait. One parent is heterozygous for cleft chin, and the other parent does not have a cleft chin. What is the probability that the offspring will have a cleft chin? 1 out of 4 2 out of 4 3 out of 4 4 out of 4
Answer:
2 out of 4
Explanation:
Let the allele for cleft chin be represented by A, while the alternate recessive version would be a.
A parent that is heterozygous for cleft chin would have the genotype Aa.
A parent without cleft chin would have the genotype aa.
Aa x aa
Aa Aa aa aa
Aa - cleft chinned = 2/4
aa - normal chin = 2/4
Thus, two out of every four (2/4) of their offspring would have cleft chin.
1. What are the three stages of the cellular respiration pathway, listed in the order in which they occur?
The three stages of the cellular respiration pathway are glycolysis, pyruvate oxidation, and the citric acid cycle.
What is cellular respiration?Food molecules are broken down into energy, water, and carbon dioxide during cellular respiration. In the presence of oxygen, cells respire. Multiple chemical cycles are involved in cell respiration. The Krebs cycle, phosphorylation cycle, and citric acid cycle are the cycles.
Glycolysis, the citric acid cycle, and the electron transport chain are three distinct metabolic pathways that come together to form cellular respiration. The process known as pyruvate oxidation is required in order to convert pyruvate molecules is a product.
Therefore, the citric acid cycle, pyruvate oxidation, and glycolysis are the three steps in the cellular respiration pathway.

The length and millimeters of 6 worms were 96-88 86-84 80 70
Find the mean
Answer:
The mean for the length of the 6 worms is 84 millimetres.
Explanation:
Okay, before we solve for the mean, you need to understand what the mean is in the first place.
The mean is when you add all the given numbers and then divide by the amount of numbers given.
In this case, we have the numbers 96, 88, 86, 84, 80, 70.
These are the steps:
1. Add all the numbers
96 + 88 + 86 + 84 + 80 + 70 = 504
2. Divide the total of the given numbers by the amount of numbers given.
In this case, it is 6. So it would be 504/6, which equals to 84.
Also, don't forget to put the unit.

What would happen if biologists kept introducing hares into the environment to keep the hare population at a high and constant level
And what would happen if biologists kept only the lynx population at a high and constant level
Answer:
More food is available for predators.
Explanation:
If biologists kept introducing hares into the environment to keep the hare population at a high and constant level so there is more availability of food for the predator and so the population of predator increases. If there is no predator for the hare so it will increase in number and eliminate all the vegetation of the environment while on the other hand, if the biologists kept only the lynx population at a high and constant level so it decreases the population of hares because lynx feeds on hare.
if a parent cell has 10 chromosomes, how many chromosomes will be in each daughter cell after mitosis
Answer:
10
Explanation:
Mitosis is the division of somatic cells in which the genetic content or number of chromosomes remain intact in daughter cells.
So the correct option is 10
The number of chromosomes will be 10.
MITOSIS:During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells.Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell.Thus, if a parent cell has 10 chromosomes, 10 will be in each daughter cell after mitosis.

Answer:
The words that complete the sentences are:
- EUKARYOTIC
- MULTIPLE
- CIRCULAR
Explanation:
Replication is the process whereby genetic material is duplicated into two identical copies. It is a key process that must occur prior to any cellular division (mitosis or meiosis). However, DNA replication occurs slightly different in eukaryote and prokaryote.
- Eukaryotic cells are cells that possess a membrane bound nucleus to house their NUMEROUS/MULTIPLE LINEAR chromosomes. On the other hand, prokaryotic cells do not have a membrane bound nucleus to house their SINGLE CIRCULAR chromosome.
- Due to the fact that linear chromosomes of eukaryotes are multiple in number, their replication occurs in MULTIPLE LOCATIONS but that of prokaryotic cells take place in a SINGLE LOCATION.

Plzz help will give brainiest. What pair of chromosomes do not go through crossover
Answer:
The Y chromosome do not go through crossover
Explanation:
Typically, genes from the mother and father are shuffled -- or, "cross over" -- to produce a genetic combination unique to each offspring. But the Y chromosome does not undergo crossing over, and, as a result, its genes tend to degenerate, while repetitive DNA sequences accumulate. Each chromosome is made up of DNA.
Answer:
it is the y chromosomes that do not go through crossover.
In Black Angus cattle, the color black is what type of genetic trait?
recessive
incomplete
dominan
genotype
Answer:
dominant
Explanation:
The "gene" of an organism consists of two alleles. One allele comes from each parent. A genetic trait is said to be "dominant" even if there's only one copy of dominant allele present; however, a genetic trait is said to be "recessive" if there are two recessive alleles present.
In Black Angus cattle, the dominant color is "black." They are even named after their color. The recessive trait is "red." In order for a Black Angus cattle to be red, it needs to have two alleles for the recessive trait (red). However, it is easy for the cattle to be black as long as it has one allele for the dominant trait.

explain why desert plants need the waxy coating on their leaves to survive.
Answer:
Explanation:
The leaves and stems of many desert plants have a thick, waxy covering. This waxy substance does not cover the stomata, but it covers most of the leaves, keeping the plants cooler and reducing evaporative loss. Small leaves on desert plants also help reduce moisture loss during transpiration.
