How does binding of complement-opsonized microbes to CR1 facilitate clearing of the microbe from the host? a. Secretion of proinflammatory cytokines b. All of the answers occur as a result of CR1 binding of complement-opsonized microbes. c. Promotion of phagocytosis of opsonized microbes by leukocytes d. None of the answers occur. e. Mediating phagocytosis of C3b-opsonized pathogen by B cells
Answer:
The correct answer is - b. All of the answers occur as a result of CR1 binding of complement-opsonized microbes.
Explanation:
Binding of complement - opsonized to CR1 makes the microbe palatable to the phagocyte for the phagocytosis and removes the microbe from the host cell. The mechanism of the removal takes place by the promotion of phagocytosis by the leukocytes.
Secretion of the pro-inflammatory cytokines also takes place in the clearing of the microbe and the phagocytosis is mediated by the B cells of the C3b-opsonized pathogen.

Which of the following is a peptide bond?
A.C-H bond
B.N-H bond
C.C-C bond
D.C-N bond
Answer:
The correct answer is - D.C-N bond
Explanation:
A chemical bond is formed between the carboxyl group of an amino acid to the amino group of the other amino acid and release a water molecule. It is a dehydration synthesis reaction.
So, the peptide bond normally formed by the reaction between amino acid from C1 of one amino acid molecule and N2 of the other amino acid molecule.
So the peptide bond that formed by this reaction is involve bonding of C-N bond.

Do you agree that wild species such as orangutans have the right to exist whether or not they are useful to humans? Explain.
Answer:
Because orangutans live in only a few places, and because they are so dependent upon trees, they are particularly susceptible to logging in these areas. Unfortunately, deforestation and other human activities, such as hunting, have placed the orangutan in danger of extinction.
Explanation:
Hope this helps ;)
Ape like organisms with red coloured hairs that are mammals and belong to the Hominidae family are called Orangutans. They are found in the rainforests and are 1.2 - 1.8 m in height.
To this open question, I don't agree with the statement.
The viewpoint can be explained as:
They have the right to exist even when they are not useful to humans as they play a vital role in the food chain and the ecosystem in which they reside.If Orangutans are withdrawn from the ecosystem then many plant species will be impacted or can vanish.Orangutan helps in seed dispersion and sustain a healthy and balanced condition of the ecosystem.The residents, trees and the ecosystem are interdependent for survival and hence, they cannot be removed.To learn more about Orangutans follow the link:

Match the types of roots to their properties. a root that is conical in shape and develops from the radicle a root that develops like a tuft of hair like roots and is short-lived a root that grows from plant parts other than roots a root that grows from branches to the ground a root that grow out of the soil adventitious root arrowRight pneumatophores arrowRight tap root arrowRight fibrous root arrowRight prop root arrowRight
Answer:
adventitious root ➡ a root that grows from plant parts other than roots
pneumatophores ➡ a root that grow out of the soil
tap root ➡ a root that is conical in shape and develops from the radicle.
fibrous root ➡ a root that develops like a tuft of hair like roots and is short-lived.
prop root ➡ a root that grows from branches to the ground
Explanation:
Adventitious roots are known to be roots that grow from a tree organ other than the root. The growth can be from the stem or leaf of that tree. This root makes it possible for vegetative propagation of plants to take place through stem or leaf cuttings. It can seen on rhizomes, corms, and tubers.
Pneumatophores are roots that grow out of the soil. They grow in saline mud and grow upward out of the mud and water. These type of root system are found in mangrove species. A tap root system is formed when the radical keeps growing and some other roots form along the tap root. They are conical in shape too.
Place the Polymerase Chain Reaction events listed below in the order in which they occur. - Double-stranded DNA is produced - DNA sample is heated - Test tube with DNA sample is placed in machine - Taq polymerase initiates DNA synthesis - DNA denatures
Answer:
1- Test tube with DNA sample is placed in machine
2- DNA sample is heated
3- DNA denatures
4- Taq polymerase initiates DNA synthesis
5- Double-stranded DNA is produced
Explanation:
The Polymerase Chain Reaction (PCR) is a technique widely used in molecular biology laboratories in order to produce many copies of a specific DNA sample. Thermocyclers are machines designed for a cyclic temperature change of the PCR. First, an initial denaturation step where DNA sample is heated to separate the double-stranded DNA into two single strands. Subsequently, 20-40 PCR cycles are repeated to produce millions of copies of a specific DNA sequence. There are three steps in each PCR cycle: 1-Denaturation to 94–98 °C (DNA strands are separated), 2-Annealing to 50–67 °C (primers bind to each DNA strand on the opposite ends of the DNA strands to be copied) and 3-Extension to 75–80 °C (Taq polymerase initiates the synthesis of complementary DNA strands).

There are three alleles for the ABO blood group in humans. Why are there only two alleles normally present in any individual?
1. The alleles for the ABO blood group always segregate independently during meiosis.
2. Each parent contributes only one allele for the ABO blood group to the offspring
3. Every gene for the ABO blood group must be recessive.
4. The alleles that determine the ABO blood group are on the X-chromosome.
Answer:
2. Each parent contributes only one allele for the ABO blood group to the offspring
Explanation:
Humans are diploid organisms, which means that our cells have two copies of the same gene. These copies are called alleles. We inherit one allele from each parent.
Just like most of our traits, we inherit our blood group from our parents. There are three alleles that determine our blood group: A, B, and O. We can get only two of them, though. Whether our blood group is A, B, AB, or O will depend on the combination of the alleles we inherited.

In pea plants the allele for tall plants in dominant to the allele for short plants, and the allele for purple flower colour is dominant to the allele for white flower colour. What is the genotype of a short plant produced from a cross between a true-breeding purple flowered pea plant and a true-breeding white flowered pea plant? *
1.TTPP
2.ttpp
3.ttPP
4.ttPp
5.TtPp
Answer:
The correct answer is - 4. ttPp
Explanation:
Given - tall is dominant over short pea plant
let assume T is dominant and t is short which is recessive
Similarly, P for dominant purple flower and p for white flower
The offspring has a short plant which means it has both t allele or recessive allele for the height of a plant by the cross of a true-breeding purple and true-breeding white:
P P
p Pp Pp
p Pp Pp
This means the offspring would have a heterozygous case for the genotype of the flower of the pea plant
Thus, the correct answer is ttPp

Applying Osmosis
On the inside of a cell, it is 75% water and 25% salt. On the outside of the cell it is 60% water, 40% salt.
A. Will water move into or out of the cell?
B. Will the cell shrink or will it swell?
C. Is the solution outside of the cell hypertonic or hypotonic?
Please help me with this! I will mark the right answer brainliest!
Answer:
a. Water will move out of the cell
b. Shrink
c. Hypertonic solution
Explanation:
a. The scenario given shows that there is greater concentration of solutes outside the cell than the concentration of solutes inside the cell because there is 75% water inside the cell and 60% water outside the cell. So by osmotic pressure, water moves out of the cell.
b. Once the cell loses water it would shrink
c. It is an hypertonic solution because the concentration of solutes outside the cell is greater than the concentration of solutes inside the cell.

How could you decrease the amount of energy an object has?
The amount of energy that an object has can be decreased by decreasing its temperature.
Let us recall that the temperature of a body is a measure of the average kinetic energy of the molecules of the body. The molecules in a body are always in constant random motion.
The kinetic energy possessed by the body is dependent on its temperature. To control the amount of energy that an object has, we either increase or decrease its temperature.
If we want the amount of energy that an object has to decrease, we simply decrease its temperature.
