Bone density of the species
Mitochondrial DNA of the species
Number of teeth of the species
Geographic location of the species
Answer:
Your answer will be Mitochondrial DNA of the species. I hope this helps.
Explanation:
The evidence that mitochondrial DNA of the species supports the idea that an evolutionary relationship exists between two hominid species. The correct option is B.
What is evolutionary relationship?Relationships formed through the worldwide process of evolution between two separate creatures are known as evolutionary relationships.
They are, in other words, the connections between two species that shared an ancestor.
A group of organisms' evolutionary relationships and histories are known as its phylogeny in science.
A phylogeny describes the relationships between creatures, including where they are assumed to have originated from, which species they are most closely related to, and other information.
Purple non-sulfur bacteria were permanently enslaved to create mitochondria.
Through the development of sophisticated protein-import machinery and the insertion of protein carriers for host energy extraction into their inner membranes, these endosymbionts developed into organelles.
Thus, the correct option is B.

If a haploid cell has 16 chromosomes in its nucleus, how many would be present in the diploid state? View Available Hint(s) for Part A 4 8 32 64
Answer:
If a haploid cell has 16 chromosomes in its nucleus, how many would be present in the diploid state? A. 4. B. 8. C. 32. D. 64. C.
Explanation:
If the haploid cell has 16 chromosomes in its nucleus, then it has 32 chromosomes in the diploid state. The option saying "32" is correct for this condition.
What is a chromosome?
The chromosomes are present in the nucleus of the eukaryotic cell, and their number varies from species to species. One species may get 4 chromosomes while others, like humans, have 46 chromosomes.
The haploid cells are formed by the process of meiosis, where the cell gets half of its genetic content from the parent cell. If the haploid cell gets 16 chromosomes, then the parent cell, which is the diploid cell, gets 32 chromosomes. In the parent cell, there are two copies of a gene, one from the paternal side and one from the maternal side. The same genetic content is transferred to the daughter cells during mitotic division.
Hence, as a haploid cell is formed with 16 chromosomes, the diploid cell has 32 chromosomes.

In which order do the events of antidiuretic hormone (ADH) secretion stimulated by plasma osmolarity occur
The order in which the ADH stimulated by plasma osmolarity occurs is:
an increase in plasma osmolarity, activation of osmoreceptor, release of ADH, reabsorption of water.
The antidiuretic hormone (ADH) is responsible for the homeostatic valance and increase in blood's volume. The activation of this hormone and how it works is as follows:
There is a low concentration of water in the body, which decreases the extracellular fluid.The decrease in the extracellular fluid results in a reduction of the plasma osmolarity, in other words, the blood volume is reduced.As a consequence, the osmoreceptors in the hypothalamus, kidneys, and carotid detect the high concentration of solutes. The hypothalamus releases ADH.The hormone travels through the blood to the kidney. There, it stimulates the reabsorption of water and reduces urine production.The body is hydrated again.
To sum up, the body detects a high concentration of solutes due to a loss of water. Then it releases ADH; as a consequence, the kidneys reabsorb water till the osmolarity decreases.

Activation of muscarinic receptors will 1. cause skeletal muscle contraction 2. increase heart rate 3. causes secretion of digestive enzymes
Given what we know about muscarinic receptors, we can confirm that the activation of these receptors will result in an increase in heart rate.
Muscarinic receptors are also often referred to as acetylcholine receptors. These are membrane receptors that tend to form G protein-coupled complexes. Though the activation of these receptors will not increase the heart rate in a direct fashion, it will do so indirectly through its interaction with acetylcholine molecules.
Acetylcholine is a very common molecule in the human body. This molecule plays the role of a neurotransmitter, meaning its job is to send signals to other cells, like in this case muscle cells in the heart.
This organic chemical signals the heart muscles to contract at slower speeds, thus decreasing heart rate. The activation of Muscarinic receptors inhibits these Acetylcholine molecules, stopping their signal and causing the heart rate to increase.

3. In the 1660s, Flemish physician Jan van Helmont grew a small willow tree in a pot of soil. He
added only water to the pot. At the end of five years, he found that the tree had gained 75
kilograms, but there was very little change in the mass of the soil. Van Helmont concluded that
the plant gained weight directly from the water. We now know that this conclusion is only
partially correct because, in addition to water, photosynthesis also requires
(1) oxygen from the atmosphere
(2) proteins from animal prey
(3) carbon dioxide from the atmosphere
(4) carbohydrates from the soil
The conclusion that can be drawn by Flemish physician Jan van Helmont is partially correct because, in addition to water, photosynthesis also requires carbon dioxide from the atmosphere. Thus, the correct option for this question is C.
What is Photosynthesis?Photosynthesis may be defined as a process through which green plants and some photosynthetic algae synthesize their own food in the form of glucose with the help of carbon dioxide and water in the presence of sunlight.
The complete reaction of photosynthesis is as follows:
[tex]6CO_2+12H_2O[/tex] → [tex]C_6H_1_2O_6+6O_2+6H_2O.[/tex]With the help of this reaction, it is identified that carbon dioxide and water act as reactants in photosynthesis while glucose and oxygen are the products. Hence, along with water, carbon dioxide must also be required in order to accomplish the process of photosynthesis.
Therefore, the correct option for this question is C.

Line 1 represents ocean levels from the surface to 2,300 feet below ocean surface. Line 2 represents ocean levels from 2,300 feet to 6,560 feet below ocean surface. Line 3 represents ocean levels below 6,560 feet under the ocean surface. Graph shows the average annual ocean heat compared to the 1993 average represented as the 0 baseline from 1993 to 2020. Vertical axis shows ocean heat content measured in 10 to the 21 power joules. It starts at negative 60 and goes up to 180 in increments of 20. The horizontal axis shows years from 1995 to 2020 in multiples of 5 years. From 1995 to 2020, Line 1 starts at 20 and has an average growth of 7 vertical units per year. From 1995 to 2020, Line 2 starts at negative 20 and has an average growth of 4 vertical units per year. From 1995 to 2012, Line 3 starts at 0 and has an average growth of 1.3 vertical units per year. Data Source: © 2021 NOAA Which statement describes the approximate average trend of ocean heat content between 2,300 and 6,560 feet under the ocean during this time period? An increase of about 130 x 1021 joules An increase of about 80 x 1021 joules A decrease of about 20 x 1021 joules A decrease of about 80 x 1021 joules
The heat content change between 1993 and 2020 is lowest in the ocean levels below 6,560 feet.
The statement that describes the approximate average trend of ocean heat content between 2,300 and 6,560 feet is; An increase of about 80 × 10²¹ joulesReasons:
The graph that represent the heat content levels of the ocean at 2,300 feet to 6,560 feet is line 2
From the graph, we have;
The ocean heat content in 1993 = -20 × 10²¹ joules
The ocean heat content in 2020 = 60 × 10²¹ joules
The increase in heat content between 1993 and 2020 is therefore;
ΔH = 60 × 10²¹ - (-20) × 10²¹ = (60 - (-20)) × 10²¹ = (60 + 20) × 10²¹ = 80 × 10²¹
The increase in heat content between 1993 and 2020 = 80 × 10²¹ joules
The correct option is; An increase of about 80 × 10²¹ joules.

The enzyme machinery responsible for mismatch repair must be able to distinguish between the template strand and a newly synthesized strand. How is that achieved in a bacterial cell, such as E. coli
Answer: For a short period of time after replication, the sequence GATC is methylated at the A only on the template strand.
In recently manufactured DNA, a mismatch has been found. The template (old) strand's T is coupled with a G in the new strand.
What effects of mismatch repair in enzyme machinery?DNA damage causes the mismatch repair enzyme MLH1 to become active. However, MLH1 expression appears to be connected to apoptotic signaling.
As well as being necessary for damage repair, When it is activated, activities that result in planned cell death are triggered.
A region of DNA containing the mismatched nucleotide and its neighbors is removed, and the new DNA strand is cut. A DNA polymerase substitutes the missing nucleotides for the missing patch.
The mismatch repair machinery separates the newly synthesized strand from the template to start the repair process (parental).
Therefore, a short period of time after replication, the sequence GATC is methylated at the A only on the template strand.
