Model of asexual and sexual reproduction.
give me a model of these, i’ll give whatever i can. it’d be a life save. best regards, happy new years.
Answer:
sexual reproduction is where a sperm and egg combine togethe r which is called a zygote. and after couple months turn into a baby(example; us humans) Asexual are things that do not need a mating partner to reproduce such as cells, they can reproduce themselves from 1 to 2 to 4 to 8 to 16 to 32 again and again. I cannot show a model but this summarizes what happens. Hope it helps, if you need a picture you can search them up

What kind of mutation is this?
Answer:
What kind of mutation - "simple base substitution" or "point mutation".
New mRNA strand - CUG CCU GCU AAU
Does the mutation affect the protein. - yes because one amino acid is different
Explanation:
Here a point mutation occurs in the gene.
What is Point mutation?A point mutation is said to occur in a genome when a single base pair is added, deleted or changed.
Here due to point mutation only a single base pair has been changed ,thus the amino acid sequence has been changed. This is because due to point mutation in the DNA strand the mRNA produced is also changed so the amino acids coded by the mrna are also changed.
A point mutation exists a genetic mutation where a single nucleotide base exists changed, inserted, or deleted from a DNA or RNA series of an organism's genome. Point mutations have a combination of effects on the downstream protein product—consequences that exist moderately predictable established upon the specifics of the mutation.

What does a vaccine do to help an immune system?
Answer:
A vaccine works by training the immune system to recognize and combat pathogens, either viruses or bacteria. To do this, certain molecules from the pathogen must be introduced into the body to trigger an immune response.
Explanation:
Basically it trains the body by giving it a little expirementation withthe sickness. After that, the body will learn how to properly fight or keep the sickness at bay.
Hope it helped!;)
A vaccine injects a little bit of whatever disease you want to protect yourself from. It's just enough that your immune system fights it off and becomes stronger against the disease.

why the pulmonary arteries have light violet blood?
Answer:
The blood in the pulmonary artery is going to the heart to collect oxygen, and therefore has a low content of oxygen. So, the blood in the pulmonary artery is a violet colour because it has low oxygen. The blood in the pulmonary vein is oxygen rich, and so it gives a scarlet color.
why are some molecules polar and others non polar
Answer:
Polarity and Non-polarity of molecules depend upon the electronegativity. The theory of electronegativity lies in entire inorganic chemistry. The more electronegative an atom, the more it seeks electrons. If one atom is more electronegative than others, it can form an ionic bond or a polar covalent bond.

What are our lungs made out of?
Answer:
The lungs are a pair of spongy, air-filled organs located on either side of the chest (thorax). The trachea (windpipe) conducts inhaled air into the lungs through its tubular branches, called bronchi. The bronchi then divide into smaller and smaller branches (bronchioles), finally becoming microscopies

In the deep water where there is no sunlight, how do bacteria and plants create
their food?
Answer:
Bacteria and Plants use the process of chemosynthesis to create/make food using chemical reactions.
Explanation:
"Autotrophs that perform chemosynthesis do not use energy from the sun to produce food. Instead, they make food using energy from chemical reactions, often combining hydrogen sulfide or methane with oxygen. ... Bacteria that live in the deep ocean, near hydrothermal vents, also produce food through chemosynthesis."
Which RNA base bonded with cytosine?
Answer:
Guanine
Explanation:
C to G and A to T
In RNA, cytosine (C) forms a base pair with guanine (G).
This pairing is based on complementary base pairing rules, where cytosine always binds with guanine through three hydrogen bonds.
In RNA, as well as in DNA, the base pairs play a crucial role in the structure and function of genetic material.
The pairing between cytosine and guanine, along with adenine (A) pairing with uracil (U) in RNA (or thymine (T) in DNA), creates the double-stranded structure of nucleic acids.
These base pairs provide stability and ensure accurate replication and transcription of genetic information, contributing to the essential functions of RNA and DNA in various biological processes.

A cell containing 10% salt is placed in a beaker of 30% salt. Is the solution is
the beaker hypertonic, hypotonic, or isotonic to the cell? *
Answer:
Hypertonic solution
Explanation:
Because a hypertonic solution occurs when more solutes are outside the cell than on the inside cell
A cell containing 10% salt is placed in a beaker of 30% salt. Is the solution is the beaker hypertonic to the cell.
What is in a hypertonic solution?Any external solution with a high solute content and a low water concentration in comparison to bodily fluids is referred to as a hypertonic solution. The net migration of water in a hypertonic solution will be from the body into the solution.
Hypertonic solutions include 10% salt content. A cell that is placed in a hypertonic environment experiences a net migration of water to the cell's exterior (from the higher water environment inside the cell). In reaction, the cell contracts.
A solution is said to be hypertonic if its salt concentration is higher than the salt concentration in the cells. The osmosis process allows water to pass through permeable cell membranes.

What is the diffrence between genotype and phenotype.....
I look like a RAT ;-;
Answer:
A genotype refers to the genetic characteristics of an organism. A phenotype refers to the physical characteristics.
Explanation:
For a particular trait, the allele C is dominant over the allele c. The Punnett square shows the genetic cross of two parents, each with genotype Cc. What percentage of the offspring will show the phenotypes of the dominant allele and the recessive allele
Answer:
There is no punnet square in this question but it can still be answered based on the information provided.
Phenotypes of the dominant allele= 75%
Phenotypes of the recessive allele= 25%
Explanation:
This question involves a single gene that encodes a particular trait. The allele C is dominant over the allele c. This means an heterozygous (Cc) will have the phenotype encoded by allele C. A dominant allele is the allele that masks the phenotypic expression of another allele. The allele being masked is the recessive allele.
According to this question, two parents, each with genotype Cc were crossed. This means that each parent will produce the gametes: C and c. Using these gametes in a punnet square (see attached image), the following genotype of offsprings will be produced:
CC, Cc, Cc and cc.
- Offsprings with genotypes CC, Cc, Cc will show the phenotypes of the dominant allele (C) because allele C is dominant. Hence, the percentage is 3/4 × 100 = 75%.
- Offsprings with genotypes cc will show the phenotypes of the recessive allele (c). Hence, the percentage is 1/4 × 100 = 25%.
