Answer:
structural
Explanation:
In addition to flight and body feathers, birds also have down feathers. Down feathers are soft and fluffy because they don't have barbules and barbicels (the structures that hook feather barbs together). Down feathers help to keep a bird warm by trapping air close to the body, which insulates the bird from the cold.

Explanation:
How many calories are required to heat 10 mL of water from 25 C to 35 C
Answer:
[tex]Q = 5,46,000[/tex] joules
Explanation:
As we know
[tex]Q = mc \Delta T\\[/tex]
Q is the Heat Energy
M is the mass of the substance releasing /absorbing heat
C is the specific heat capacity [tex]= 4200[/tex] Joules per kilogram per degree
[tex]\Delta T[/tex] is the change in temperature
Substituting the given values, we get
[tex]Q = 13 * 4200 * (35-25)\\[/tex]
[tex]Q = 5,46,000[/tex] joules
Which MOLECULES are DIRECTLY involved in protein synthesis-translation? (choose 3)
1. mRNA
2. rRNA
3. tRNA
4. cytoplasm
5. sugar
6. DNA
7. Golgi Apparatus
8. amino acid
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.

What happens to the cell at the beginning of interphase?
Answer:
Explanation:
Early interphase is called the G1 phase of the cell cycle. G1 is the time during which a cell grows to its proper size by making more cytosol, the liquid inside a cell. An increase in cell size means the cell must make more protein and membranes. ... Cells that mature and never divide again stay in the G0 phase.

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?
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)

Why do we use models in our everyday lives especially for the weather?
P.S- need the answer ASAP!! please helpppp
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.

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.
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.
