Answer:
CD40L
Explanation:
The CD40 ligand (CD40L) protein is a transmembrane glycoprotein which is expressed on activated T cells and belongs to the tumor necrosis factor (TNF) superfamily. The hyper IgM syndrome is caused by mutations in the CD40L gene, where the defective protein can no longer bind CD40 on antigen-presenting cells. The X-linked Hyper IgM syndrome is characterized by abnormal levels of immunoglobulins, i.e., low levels of IgG and IgA, and increased/normal levels of IgM. Because CD40L gene is located on the X chromosome, this disorder is observed much more frequently in males than in females.

Why would an aquatic organism need a contractile vacuole?
Answer:
Contractile vacuoles protect a cell from absorbing too much water and potentially exploding by excreting excess water. Wastes, such as ammonia, are soluble in water; they are excreted from the cell along with excess water by the contractile vacuoles

At a deep sea whale fall, the Atlantic hagfish, the crustaceans, and the sand make up which of the following?
Answer:
I would say part of an ecosystem and community.
Explanation:
An ecosystem is a biological community of interacting organisms and their physical environment .In the bottom of the sea,there are already many animals living here and when the whale fall appears at the bottom of the ocean it becomes apart of the ecosystem as it provides them with food.
This is because when a whale dies, its body often falls to the seafloor. The whale's body then becomes food and shelter for organisms in the deep sea. This is called a whale fall. A deep-sea whale fall might support 200 different species for as long as 10 years! Larger species, such as Atlantic hagfish, are the first to arrive to feed on the whale flesh. Later, smaller species of snails and crustaceans come to eat the remaining flesh. Worms burrow into the sand beneath the whale body, and bacteria feed on the whale bones.
Answer:
Part of an ecosystem
Explanation:
The Atlantic hagfish and the crustaceans are living organisms. The sand is a nonliving part of the environment. An ecosystem is made up of living organisms and the nonliving parts of their environment. So, the Atlantic hagfish, the crustaceans, and the sand make up part of an ecosystem.

What is the interference?
a. 37.5%
b. 25.%
c. 62.5%
d. 75%
Answer:
I = 62.5%
Explanation:
Available data:
the wild-type DND1 gene confers resistance to attain viruses. Strains are susceptible to virusesThe EDS1 gene confers resistance to powdery mildew, a type of fungal infection The genes are linked, eight map units apart on chromosomeA third gene, IR 1. imparts resistance to certain lepidopteran leafminers and is 10 map units from EDS1 and 18 map units from DNDIThe observed double crossover rate is 0.3%According to this information, we can picture the position of each gene in the chromosome
---DND1----------------------EDS1-----------------------------------IR1---
║---------- 8MU---------║------------------10MU-------------║
║------------------------------18MU------------------------------║
The map unit is the distance between the pair of genes for which one of every 100 meiotic products results in a recombinant product.
1% of recombinations = 1 map unit = 1cM. The maximum recombination frequency is always 50%.
So, if we know the distances between genes, we know their recombination percentages.
DND1-EDS1 = 8 MU = 8% recombinationEDSI-IR1 = 10 MU = 10% recombinationTo calculate interference, first, we need to know the coefficient of coincidence, CC.
CC= observed double recombinant frequency/expected double recombinant frequency
Note:
observed double recombinant frequency=total number of observed double recombinant individuals/total number of individuals expected double recombinant frequency: recombination frequency in region I x recombination frequency in region II.CC= (0.003)/(0.08 x 0.1)
CC=0.003/0.008
CC=0.375
CC = 37.5%
The coefficient of interference, I, is complementary with CC.
I = 1 - CC
I = 1 - 0.375
I = 0.625
I = 62.5%

The human eye is filled with a clear fluid called the aqueous humor. The production, flow, and drainage of this fluid is an active and continuous process which keeps the healthy eye at an intraocular pressure of about 15 mmHg. If the drainage becomes obstructed, fluid accumulates in the eye resulting in an increase of this pressure to the 25 to 50 mmHg range and the clinical onset of glaucoma. What is the pressure of 30 mmHg expressed in units of psi (pounds per square inch)
Answer:
The pressure will be "0.579 psi".
Explanation:
The given value is:
Hg,
= 30 mm
Density of mercury (Pm),
= 13600 kg/m³
As we know,
1 psi = 6895 N/m²
Now,
The pressure will be:
= [tex]30 \ mm \ of \ Hg[/tex]
= [tex]30\times 10^{-3}\times Pm\times g[/tex]
On substituting the given values, we get
= [tex]30\times 10^{-3}\times 13600\times 9.8[/tex]
= [tex]3,998,400\times 10^{-3}[/tex]
= [tex]3,998.4 \ N/m^2[/tex]
So,
The pressure of 30 mm of Hg will be:
= [tex]\frac{3,998.4}{6895}[/tex]
= [tex]0.579 \ psi[/tex]
