Answers

Answer:

In order to predict weather.

Explanation:

We use models in our everyday lives especially for the weather in order to gain information about the weather of next few days. This model is very necessary because it predicts the weather which is very important for the farmers. Observations of pressure, wind, temperature and moisture are obtained from different instruments such as ground sensors and weather satellites. The observations or data are put into the models which gives information about the weather.

The diagram shows a model of a section of double-stranded DNA. The straight lines and dotted lines represent chemical bonds between the
components of the molecule.
During DNA replication, which chemical bonds break apart? Select all that apply.

Answers

During DNA replication, the hydrogen bonds must be broken between the complementary nitrogenous bases in the DNA double helix. Hope this helps! Maybe mark me the brainliest??

The DNA has two double strands, and they have different chemical bonds, so during the DNA replication, the hydrogen bonds that are present between the two strands break to separate the DNA.

What role does DNA replication play?

DNA replication is the process of making two DNAs from a single DNA, and here the hydrogen bonds that are present between the bases, such as thymine and adenine, which have two hydrogen bonds, and guanine and cytosine, which have three hydrogen bonds, break. The purpose of DNA replication is to make a copy of the genetic content of the cell so that it can be passed to other cells.

Hence, the DNA has two double strands, and they have different chemical bonds, so during the DNA replication, the hydrogen bonds that are present between the two strands break to separate the DNA.

While looking at a cell under a microscope you notice there is no nucleus and the

chromosomes are double stranded (they have 2 sister chromatids). What phase of mitosis is

the cell probably in?

Answers

Answer:

This is the Prophase. Mitotic Prophase,

Explanation:

The process  cell division where the cells divides two similar daughter cells(2n) is called mitosis. Therefore it is called  a multiplication division because two daughter cells are  form from a single  the mother cells. Each of the daughter cells can also undergo Futher divisions.

It is the second stage fist  mitotic cells division after the first phase called Interphase.

In this stage, the nuclear membrane disappear, nucleolus disintegrate and  the nucleus disappeared  This is followed  by the constriction of the chromosome to sister chromatids.

The constricted nuclear membrane leads to the releases of the chromatids This is  followed by the formation of the spindles fibers which are needed for the movement of chromosome for cross over.

other phases are Interphase Prophase Metaphase Anaphase Telephase(IPMAT)

Which MOLECULES are DIRECTLY involved in protein synthesis-translation? (choose 3)

2. rRNA
3. tRNA
4. cytoplasm
5. sugar
6. DNA
7. Golgi Apparatus
8. amino acid

Answers

1,4,2 those are the answers in order

The translation is directly facilitated by mRNA, tRNA, and rRNA. A specific DNA sequence termed a gene is used as a template during gene transcription to produce a messenger RNA (mRNA), so 1, 2, and 3 are directly involved.

What is the process of protein synthesis?

The ribosomes are the next location this mRNA visits before being employed to translate it into a protein.

A ribonucleoprotein complex called the ribosome is made up of proteins and ribosomal RNA (rRNA) sequences.

The linear order of the amino acids that will be added to the protein is indicated by the triplets of nucleotides, or "codons," in the mRNA.

Therefore, the process of translating mRNA into the chain of amino acids that makes up the produced protein occurs in ribosomes in the cytoplasm of the cell.

Being genetically identical to the parent is most advantageous for organisms in which situation?
A.
Many offspring are needed in a very short amount of time.
B.
The environment is just like the one the parent lived in successfully.
C.
Mates cannot be found easily and the species is dying out.
D
The environment is changing and fast reproduction is needed.

Answers

Answer:

B

Explanation:

In asexual reproduction organisms give rise to genetically identical clones and reproduce in higher amounts, hence option d environment is changing and the need for fast reproduction is correct.

What is genetically identical?

The children are clones of both the parent and each other. Asexual reproduction has several advantages, including the ability to fast increase the population when conditions are favorable.

There is just one parent required. During sexual reproduction, two people's genetic material is united to generate genetically diverse children who differ from their parents.

It is assumed that the genetic variety of sexually generated offspring gives species a higher chance of survival in an uncertain or changing environment.

Therefore fast reproduction is needed, because the environment is changing, and asexual reproduction makes a higher population, hence option d is correct.
