Seeds divide by meiosis because mitosis is a continuous process of division in animal multicellular organisms where as meiosis occurs in plants to produce gametophytes.

In many ways, meiosis is a lot like mitosis. Since cell division occurs twice during meiosis, one starting cell can produce four gametes (eggs or sperm). In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase.

What is probability, and how is it used with Punnett squares to predict the outcomes of genetic crosses?

weeeeeb [17]

Answer:

Probability is the chance that a given event will occur. The principle of probability allows us to predict the possible combinations of phenotypes in a genetic cross by using a diagram called Punnett squares. This diagram represents alleles and gives us the genetic variations formed during a cross. For example, a flower has one dominant allele for a blue color, which is represented by capital T, and one recessive allele for a pink color, which is represented by small t. When this flower is crossed with another flowering plant with the same type of alleles, which is Tt, the combinations produced for their offspring includes TT, Tt, tT, and tt.

Which statement describes an advantage of using biometrics for physical access control?

Soloha48 [4]

Answer: a.The individual always has the biometric in their possession.

Explanation:

Biometrics is a term that is used for the technology that is used to measure the bodily features and making a calculation on that basis. It is a method that can be used for the purpose of identification and authentication for the purpose of access control.

Among the given options, a.The individual always has the biometric in their possession. is the correct option. This is because of the fact that biometric measurements can be based upon physical characteristics such as fingerprints, retinal scans, and facial recognition. These features are common and unique to every human being. Hence, biometric system can be advantageous for physical access control.

Which of the following does NOT characterize proteins?

8090 [49]

Answer:

The answer is C) They appear to be the molecular carriers of coded hereditary information.

Explanation:

Why NOT C) They appear to be the molecular carriers of coded hereditary information?

This is the job of the nucleic acids. It is composed of nucleotides which are the basic units of DNA and RNA. They carry genetic information about a certain organism.

<h3 /><h3>True of proteins:</h3>

A) They may be denatured or coagulated by heat or acidity.

Denaturation is the destruction of the protein's secondary and/or tertiary structures. The primary structure is not disrupted due to the tough peptide bonds and can only be broken down by acid. For heat denaturation, hydrogen bonds are destroyed, as in cooking of egg whites and medical equipment sterilization.

B) They have both functional and structural roles in the body.

There are many kinds of proteins that have functional and structural roles like hormones (FSH, LH), antibodies (IgA, IgM), enzymes (lipase, amylase), for storage/transport (hemoglobin, ferritin), and locomotion (actin, troponin).

D) Their function depends on their three-dimensional shape.

Just like hemoglobin, it's quaternary structure can carry 4 molecules of iron in one go. Enzymes are shaped accordingly to fit a specific substrate (lock-and-key model)
