Answer:
Regeneron and mAb114
Explanation:
The Ebola virus disease is a harmful viral hemorrhagic disease caused by ebolaviruses, which have a high risk of death (approximately 20% to 90%). In December 2019, the U.S. Food and Drug Administration (FDA) approved Ervebo, which is the first vaccine approved by the FDA with the aim to prevent the Ebola virus disease. Nowadays, there is no antiviral treatment approved by the FDA for patients with Ebola; however, there are two antiviral drug treatments named regeneron (REGN-EB3) and mAb114, which have shown good efficacy to treat the Evola virus. Currently, both antiviral drugs are being used in patients with Ebola.

1. Let's suppose that a gene affecting pigmentation is found on the X chromosome (in mammals or insects) or the Z chromosome (in birds) but not on the Y or W chromosome. It is found on an autosome in bees. This gene exists in two alleles, D (dark), which is dominant to d (light). What would be the phenotypic results of crosses between a true-breeding dark female and a true-breeding light male, and the reciprocal crosses involving a true breeding light female and a true-breeding dark male, in the following species
Note: The question is not complete. The following species are:
1. Birds
2. Drosophila
3. Bees
4. Human
Answer and Explanation:
1. BIRDS
Birds have Z-W breeding system, males being ZZ and females being ZW
Cross 1: true-breeding dark female and a true-breeding light male
Parental) ZDW x ZdZd
F1) 1/2 = 50% of the progeny will be dark, ZDZd (males)
1/2 = 50% of the progeny will be light, ZdW (Females)
Cross 2: true-breeding light female and a true-breeding dark male
Parental) ZdW x ZDZD
F1) 100% of the progeny will be dark, ZDZd + ZDW (both sexes)
2. DROSOPHILA
They have the X-Y system, so
Cross 1: true-breeding dark female and a true-breeding light male
Parental) XDXD x XdY
F1) 100% of the progeny will be dark, XDXd + XDY
Cross 2: true-breeding light female and a true-breeding dark male
Parental) XdXd x XDY
F1) 50% of the progeny will be dark, XDXd (Females)
50% of the progeny will be light, XdY (Males)
3. BEES
Haplo-diploid system
Cross 1: true-breeding dark female and a true-breeding light male
Parental) DD x d
F1) 100% Dark individuals
Cross 2: true-breeding light female and a true-breeding dark male
Parental) dd x D
F1) 50% of the progeny will be dark, Dd (females)
50% of the progeny will be light, d (males)
4. HUMAN
X-Y System
Cross 1: true-breeding dark female and a true-breeding light male
Parental) XDXD x XdY
F1) 100 % of the progeny will be dark, XDXd + XDY
Cross 2: true-breeding light female and a true-breeding dark male
Parental) XdXd x XDY
F1) 50% of the progeny will be dark, XDXd
50% of the progeny will be light, XdY
I'm dropping out
I'm tired of University, I'm sick of all my professors for treating me harshly especially during these hard times, and I hate taking midterms.
I'm currently a college freshman in the middle of the semester, and things have been pretty tough. I've been procrastinating the whole week because I had everything going on and I couldn't keep up. I'm a biology major (pre-med) and I have to take two science classes. I suck at managing time and I suck at studying. I feel like I cannot do this. Also, whenever I do my assignments, my professors grade so friggen harshly & give me unfair grades even though I work all the way through midnight finishing it.
I'm a good student, it's just that you know some people can be burned out. I am burned out and college has just been draining my soul each day. Should I drop out?

what will happen to energy levels in an ecosystem if the water cycle is disrupted
Answer:
Okay if the water cycle is disrupted ...the energy levels in an ecosystem will decrease
Explanation:
This is mainly because water is mainly used in energy recyclability and so that water is converted to energy through the ecosystem and the presence of water makes the energy to be there in adequate and so if the water cycle is disrupted the energy will decrease

Humans are able to move their shoulder 360 degrees. What morphological features aid in this degree of motion (i.e. which bones)? Examine the bat wing below. Is there the same degree of motion? Explain why or why not.
Answer:
This question is incomplete because of the absence of bat diagram discussed in the question
Explanation:
Humans body contains several joints that allows from movement of bones at some junctions called the "joints". Joints are points where two bones meet. Examples of the human joints include the ball and socket joints, hinge joint, pivot joint, gliding joint, saddle joint. The type of joint in the human shoulder that allows for 360 degrees rotation is the ball and socket joint. It involves a bone that has a round head like that of a "ball" which can fit into an open cup-like shape called the "socket", hence the reason for the name. This joint allows for movement in all directions.
The bat wing does not move at the same degrees (360°) as it does not move in all directions - the wing has an up and down movement which is more of a 180° movement and not a 360° movement.

CONCLUSIONS: Genetic counseling is useful in predicting the probability of a child being born with a Mendelian inherited trait. Sickle cell anemia is caused by a recessive allele. A couple would like to know the chances of their child having sickle cell anemia. Parent #2 has the disease; parent #1 does not. Based on phenotype, parent #2 would have the genotype, ss. Parent #1 could be genotype, SS or Ss. Punnett Squares have been set up for crosses using both possible genotypes of parent #1. Should the couple be concerned that their child may have sickle cell disease? Why or why not?
Answer:
Yes, if parent 1 is Ss then there is a 50% chance the child will have it.
Explanation:
A sample of peptide of unknown sequence was treated with trypsin to produce the following smaller peptides:
1) Met-Val-Ser-Thr-Lys
2) Val-Ile-Trp-Thr-Leu-Met-Ile
3) Leu-Phe-Asn-Glu-Ser-Arg
Another sample of the same peptide was treated with chymotrypsin and gave the following smaller peptides:
1) Asn-Glu-Ser-Arg-Val-Ile-Trp
2) Thr-Leu-Met-Ile
3) Met-Val-Ser-Thr-Lys-Leu-Phe
What is the sequence of the original peptide?
Answer:
The sequence is >> Met-Val-Ser-Thr-Lys-Leu-Phe-Asn-Glu-Ser-Arg-Val-Ile-Trp-Thr-Leu-Met-Ile, or abbreviated M-V-S-T-K-L-F-N-E-S-R-V-I-W-T-L-M-I
Explanation:
Trypsin is a serine protease enzyme capable of hydrolyzing different types of proteins. This enzyme is used in biotechnology and molecular biology to hydrolyze at the carboxyl side of arginine or lysine residues. Moreover, chymotrypsin is another digestive protease that also catalyzes the breakdown of proteins into small polypeptide chains. This enzyme cuts the C-terminal side of aromatic amino acids such as tryptophan (W), tyrosine (Y) and phenylalanine (F) on peptide chains.

briefly explain the relationship between cells, organs and tissues
Answer/Explanation:
Cells of a similar type are organized together to make tissues. Different types of tisues come together to perform a similar function as part of organs.
For example, take the organ the stomach. There are various tissues that make up the stomach, including, for example, mucosa, and muscle tissue.
The mucosa tissue of the stomach is made up of secretory cells such as parietal cells, which secrete hydrochloric acid, and foveolar cells which produce mucus that protects the lining of the stomach.

Assume cube B was broken into many irregularly shaped pieces. Compared to the density of the entire cube, the density of one of the pieces would be
Answer:The same
Explanation: even thought the cube is split in many pieces the density stays the same
Because breaking the thing into pieces divides the mass and volume by the same factor, the density does not change. Additionally, regardless of a substance's size, its density is constant.
What is density relation with shape of object?An intensive property is density. This implies that the density of the substance will remain constant regardless of the shape, size, or amount of the thing.
Each component of the thing would have the same density even if you divided it into a million pieces.
For instance, despite the cube being divided into numerous parts, its density remains constant.
In a solid, the atoms or molecules are typically arranged in an orderly or occasionally crystalline structure,
Whereas in a liquid, they are free to move around with little restrictions. Because of this, the solid has a higher density.
Therefore, the density of one of the pieces is remained unchanged.
