Answer:
They both had a tail as an embryo.
Explanation:
Both human and dogs have tail as an embryo. Temporary tail-like structures are present in the human embryo. These tail like structure develop around the fifth or sixth week of gestation, having about 10 to 12 vertebrae and removed when it reached to its full development stage while on the other hand, tail present in dog's embryo also developed with time and we can see when the dog baby is fully formed.
Answer:
They both had a tail as an embryo.
Their arm and leg structure is similar but may have a different function.
Explanation:
They both had a tail as an embryo.Vestigial structures are those body parts that have lost or reduced their original function during the evolution of a species. These vestigial structures might be found in many animals, including human beings. Vestigial structures were plenty functional for common ancestors. But with evolution, they degenerated, stunted, and became rudimentary for some of the new species.
During the first 4 months of embryogenesis, all mammals have a tail at some point in their development. Dogs develop this structure and keep it during their whole lives, but humans lose it with time during embryogenesis. The tail disappears, and its forming vertebras get fussed with each other composing the coccyx, which represents a vestigial structure. This tailbone is the remnant of a missing tail.
In many animals, the function of the tail is to stabilize, equilibrate and mobilize. But in humans, the coccyx, located at the end of the vertebral column, has lost this original function.
Their arm and leg structure is similar but may have a different function.The fact that whales, humans, and dogs all have the same bones in the same order, but they matured differently in later embryological development, is an example of homologous characters.
Homologous characters have the same fundamental structures. They also share the same relations with adjacent structures, and they have the same embryological development.
These structures might show variations between organisms exhibiting them, according to their function and to the environment in which the organism lives.
These homologous characters are common in organisms related and that share a common ancestor.
Developing a new vaccine takes about 5-10 years. So how is it possible to develope Corona vaccine so quickly?
Answer:
vaccines were designed by using new technologies (i.e., RNA-based vaccines and adenovirus-based vaccines)
Explanation:
RNA-based vaccines are vaccines based on the delivery of specific messenger RNA (mRNA) sequences that are capable of encoding only one viral protein, thereby preventing the complete viral cycle/replication. Subsequently, this protein is recognized by the immune system that generates memory immunity by synthesizing specific antibodies against this protein (in this case, the spike S protein). On the other hand, adenovirus-based vaccines are vaccines designed by inserting a transgene cassette into an adenovirus which is used as vector to produce one specific viral protein inside the host. Like mRNA vaccines, this antigenic viral protein is then recognized by the immune system in order to produce antibodies against a defined protein epitope, thereby producing memory immunity.

The cell membrane is made up of a lipid bilayer as shown in the model. Which of the following describes the structure and function of the cell membrane?
56 points!!!!!!
Answer:
The hydrophilic head groups of the lipid molecules are exposed to the outside of the cell and the cytoplasm, which is a water-like environment. The hydrophobic tails form an oily layer inside the membrane that keeps water out of the cell
Explanation:
Cell membrane is selectively permeable in nature. The hydrophilic head groups of the lipid molecules are exposed to the outside of the cell, which is a water-like environment and hydrophobic tails form an oily layer inside the membrane. Thus, correct option is A.
What is Plasma Membrane?Plasma membrane is also known as the cell membrane. It is found in all types of cells that separates the interior of the cell from the outside environment. In bacterial and plant cells, a cell wall is also found which covers the cell membrane.
The cell membrane consists of three classes of amphipathic lipids: phospholipids, glycolipids, and sterols. Plasma membrane is selectively permeable in nature, it allows only some material to pass through it while blocks other material from entering through it.
The portions of the integral membrane protein found inside membrane are hydrophobic, while portions which are exposed to the cytoplasm or extracellular fluid tend to be hydrophilic in nature. Molecules that are hydrophobic can easily pass through the plasma membrane while hydrophilic particles cannot pass through the membrane easily.
Therefore, correct option is A.

When the muscle is stimulated, calcium ions are released from its store inside the sarcoplasmic reticulum, into the sarcoplasm (muscle ). ... The SR is smaller and less elaborate, and stores less calcium ions.

You added 20 g of NaCl to 100 g of water. What is the percent by mass of the solute?
Answer: We are given:
Mass of solvent (water) = 100 grams
Mass of solute (NaCl) = 20 grams
Mass of the Solution:
Mass of Solution = Mass of Solute + mass of Solvent
100 + 20 = 120 grams
Mass Percent of NaCl:
We know that
mass percent of NaCl = (Mass of NaCl / Mass of Solution) * 100
replacing the variables
Mass% of NaCl = (20 / 120)*100
Mass% of NaCl = 100 / 6
Mass% of NaCl = 16.67%

which statement describes what happens with ATP during glycolysis?
A) more ATP is produced than is used
B) glycolysis splits ATP
C) more ATP is used than is produced
D) glycolysis does not make any ATP
Answer:
A. more ATP is produced than used
Explanation:
Regulation of glycolysis
Several steps in glycolysis are regulated, but the most important control point is the third step of the pathway, which is catalyzed by an enzyme called phosphofructokinase (PFK). This reaction is the first committed step, making PFK a central target for regulation of the glycolysis pathway as a whole^1
1
start superscript, 1, end superscript.
PFK is regulated by ATP, an ADP derivative called AMP, and citrate, as well as some other molecules we won't discuss here.
ATP. ATP is a negative regulator of PFK, which makes sense: if there is already plenty of ATP in the cell, glycolysis does not need to make more.
AMP. Adenosine monophosphate (AMP) is a positive regulator of PFK. When a cell is very low on ATP, it will start squeezing more ATP out of ADP molecules by converting them to ATP and AMP (ADP + ADP \rightarrow→right arrow ATP + AMP). High levels of AMP mean that the cell is starved for energy, and that glycolysis must run quickly to replenish ATP^2

You want to make 1 ton ration of an 18% protein ration using corn (12%) and soybean meal (22%). How much of each will he have to mix together? Show your work for full credit.
Answer:
To make a 1 ton ration of an 18% protein ration using corn (12%) and soybean meal (22%), 0.6 tons of soybean meal and 0.4 tons of corn are needed
Explanation:
Using the Pearson’s Square calculations:
1. Subtract across the diagonal:
a. 18% - 12% = 6 parts soybean meal
b. 18% - 22% = 4 parts corn
2. Sum the parts:
a. 6 parts soybean meal + 4 parts corn = 10 totalparts
3. Divide each part by the total to calculate the percentage of each feed to include in the ration:
a. 6 parts soybean meal ÷ 10 total parts * 100 = 60.0% soybean meal
b. 4 parts corn ÷ 10 total parts * 100 = 40.0% corn
So, to make 1 ton ration of an 18% protein ration using corn (12%) and soybean meal (22%),
60% of soybean meal is needed = 60/100 * 1 ton = 0.6 tons of soybean meal
40% of corn is needed = 40/100 * 1 ton = 0.4 tons of corn
