Answer:
B, The sun.
Explanation:
The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers, such as plants and algae, use energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter. This process begins the flow of energy through almost all food webs.

Explanation:
Humans may have Rh blood or Rh- blood. A person who is Rh (R) has a certain type of protein on the red blood cells. A person who is Rh- (r) does not have this particular protein. In humans, Rh dominates Rh-. Normal insulin (I) production dominates abnormal insulin production (i) (diabetes). If both parents are heterozygous for both Rh and normal insulin production, what phenotypes would they produce in their offspring
Answer:
- Rh, normal insulin
- Rh, no insulin
- Rh-, normal insulin
- Rh-, no insulin.
Explanation:
This question involves two genes; one coding for Rhesus factor and insulin product. The allele for Rh blood and normal insulin dominates that of Rh- and no insulin.
According to this question, if both parents are heterozygous for both Rh and normal insulin production and cross, i.e. RrIi × RrIi, the following phenotype of offsprings will be produced (see punnet square):
- Rh, normal insulin (R_I_)
- Rh, no insulin (R_ii)
- Rh-, normal insulin (rrI_)
- Rh-, no insulin (rrii)

You are working with a mixed population of cells that includes some cells expressing CD95 on their surfaces. Design an experimental protocol using Fluorescence-Activated Cell Sorting (FACS) to determine how many CD95-expressing cells are dividing at any given time.
Answer:
Fluorescence-Activated Cell Sorting or FACS is a method that allows us to sort out different cell types on the basis of fluorescence emitted by cell membrane components bound compounds.
In the case of CD95 integral protein which is known for highly glycosylated, if use antibodies against cells with CD95 marker, will not identify glycans and can’t be targeted by antibodies as antibodies only recognize protein structures.
Therefore, two different proteins should be used in order to get the correct sorting of cells. One of these would bind to these glycosylations, and the other would be antibodies (with a fluorescent tag) against first.
explain why the use of blood type for peternity testing is not conclusive
Answer:
Although blood group studies cannot be used to prove paternity, they can provide unequivocal evidence that a male is not the father of a particular child. Since the red cell antigens are inherited as dominant traits, a child cannot have a blood group antigen that is not present in one or both parents.

Which of the following would eat a hamburger with lettuce on it?
A) carnivore
B) detritivore
C) herbivore
D) omnivore
An Omnivore would eat a hamburger (animal) with lettce (plant) on it. Therefore option (D) is correct.
What do you mean by Omnivore ?
An animal classified as an omnivore consumes both vegetation and other animals. Some omnivores, such as carnivores that consume herbivores and other omnivores, will hunt and consume their meal. Some individuals are scavengers and will consume dead things. Many people eat eggs that belong to other species.
Not all types of plants are consumed by omnivores. Omnivores, unlike herbivores, are unable to digest some components of grains or other non-fruit-producing plants. However, they are able to eat fruits and vegetables. In this simulation, some of the insect omnivores are pollinators, which are crucial to the life cycle of several plant species.
Therefore, omnivore is the correct option (D) among other options.

g Knowing if a bacterium is Gram-positive or Gram-negative is important in medicine because it tells us what type of antibiotic will be used (e.g., penicillin for Gram-positive bacteria and mycins, like streptomycin, for Gram-negative bacteria). Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. a True b False
Answer:
This is true.
Explanation:
Knowing whether a bacteria is gram positive or negative will help to narrow down the types of pathogen it could be and will determine which antibiotics will be effective against it.
Knowing whether a bacteria is gram positive or gram negative will help to understand the kind of infection it may cause and thus help in determining the kind of antibiotic it needs.
What are gram-positive and gram-negative bacteria?The bacteria that have a thick layer of peptidoglycan but no outer lipid membrane are called Gram-positive bacteria. The bacteria that have a thin layer of peptidoglycan and an outer lipid membrane are called gram-negative bacteria.
Gram-positive bacteria do not have an outer lipid membrane and hence they retain the crystal violet in the thick peptidoglycan during gram staining and it is fixed by iodine.
The outer lipid membrane that is possessed by the Gram-negative bacteria does not allow them to retain the crystal violet and hence only the counterstain safranin is visible in the gram staining method.
The technique of Gram staining was developed by the bacteriologist Hans Christian Gram in 1884. While this method cannot tell the specific strain of a bacteria, it can be used as a quick and easy way for narrowing down the basic criteria of distinguishing the bacteria among the two main groups.
Therefore, knowing whether a bacteria is gram positive or gram negative will help to understand the kind of infection it may cause and thus help in determining the kind of antibiotic it needs.

Is a pig crossed with a chimp possible, I just read an article about this and the person who had the idea was someone with the last name MCkarther PH.D. it made the news.
Answer:
The cross between two different species is called hybridization. The truth is that, for hybridization to occur, the species in question must have a certain kinship with each other, that is, they must belong to the same family of animals. An example is the cross between tigers and lions, pigs and wild boars, donkeys and donkeys, etc. Now, if there is no such familiarity between species, the truth is that hybridization will not be possible, which is the case of pigs and chimpanzees with each other.
All the following stages must occur for a woman to get pregnant. However, after which stage can a woman be described as pregnant?
Answer: The legislation repeatedly refers to that point as "20 weeks after fertilization." Medically, however, a pregnancy is generally "dated" from "gestation," defined as the time of the woman's last menstrual period, because that is a date most women can pinpoint.

D. Two diploid cells are produced.
During meiosis II, the process of cell division that follows meiosis I, a total of four daughter cells form that are haploid in form and present in option A as the daughter cells are called as gametes here.
What is meiosis?Meiosis is a type of cell division that results in the production of haploid cells from a diploid cell, and during meiosis, two rounds of cell division occur, referred to as meiosis I and meiosis II, and in meiosis I, the homologous chromosomes pair up and exchange genetic material in a process called crossing over. In meiosis II, each haploid daughter cell produced in meiosis I divides again, and the sister chromatids, which are identical copies of the same chromosome, separate from each other.
Hence, during meiosis II, the process of cell division that follows meiosis I, a total of four daughter cells form that are haploid in form and present in option A.
