How can one species turn into another species that is completely different

Answers

Answer:

Evolution

Explanation:

Answer:

One species does not "turn into" another or several other species -- not in an instant, anyway. The evolutionary process of speciation is how one population of a species changes over time to the point where that population is distinct and can no longer interbreed with the "parent" population.

1) What is the acceleration of a 40 kg object pushed with a force of 400 N?


2) What is the force on an 800 kg rock being thrown at 2.5 m/s2?


3) What is the mass of a ball being rolled at 3.5 m/s2 from a 30 N force?

Answers

Answer:

a = 10 m/s²

F = 2000 N

m = 8.57 Kg

Explanation:

1) What is the acceleration of a 40 kg object pushed with a force of 400 N?

Acceleration of object = ?

Mass of object = 40 Kg

Force on object = 400 N

Solution:

Formula:

F = ma

by putting values,

400 N = 40 Kg × a

a = 400 N/ 40 Kg   ( N = Kg.m /s²)

a = 10 m/s²

2) What is the force on an 800 kg rock being thrown at 2.5 m/s2?

Acceleration of object = 2.5 m/s²

Mass of object = 800 Kg

Force on object = ?

Solution:

Formula:

F = ma

by putting values,

F = 800 Kg × 2.5 m/s²

F = 2000 Kg. m/s²  ( N = Kg.m /s²)

F = 2000 N

3) What is the mass of a ball being rolled at 3.5 m/s2 from a 30 N force?

Acceleration of object = 3.5 m/s²

Mass of object = ?

Force on object = 30 N

Solution:

Formula:

F = ma

by putting values,

30 N = m ×  3.5 m/s²

m = 30 N / 3.5 m/s²   ( N = Kg.m /s²)

m = 8.57 Kg

A woman has blood Type A, her baby has blood Type AB: Is it possible that a man who has the blood Type A could be the father? Show the Punnett Square and explain.

Answers

Answer:

No, it is not possible

Explanation:

Humans use the ABO blood group system where the A and B alleles are dominant over allele O but codominant with one another.

This system is such that;

Type A can only have genotype: iAiA or iAi

Type B can only have genotype: iBiB or iBi

Type AB can only have genotype: iAiB

Type O can only have genotype: ii

According to this question, a woman has blood Type A (iAiA or iAi) and her baby has blood Type AB (iAiB). This means that the father definitely contributed the allele B in order to have a baby with type AB. It also means that, according to the question, IT IS NOT POSSIBLE FOR A "Type A" father to produce that baby (see the punnet square attached).

Note: The father must contain an allele B in his genotype i.e. the father must be either type B (iBiB or iBi) or type AB (iAiB)

Sickle Cell anemia is a recessive trait that causes blood cells to be misshaped. A woman who has no history of sickle cell anemia marries a man whose father had sickle cell anemia. What are their genotypes?

Answers

Answer:

See the answer below

Explanation:

Let us assume the sickle cell anemia allele to be S and the alternate, non-sickle cell allele to be A.

Since the woman has no history of sickle cell in her family, she is totally free from the trait and, hence, would have the genotype of AA.

The man's father had sickle cell anemia. This means that the man has, at least, one sickle cell allele in his genotype with the other allele depending on the genotype of his mother. Hence, the man can be AS or SS depending on the genotype of his mother.

What could happen if two of the base pairs on this strand of DNA were switched?

Answers

A: a different protein would be made

And miss sense mutation is when the change of a single base pair causes a substitution of a different amino acid in the resulting protein. This amino acid substitution may have no effect, or it may render the protien nonfunctional

In the DNA structure if the two base pairs exchange it leads to creating a mutation in the sequence and makes different proteins, hence option A is correct.

How do DNA base pairs change the protein?

A mutation is any kind of change that leads to the creation of an abnormal protein, DNA has genetic information to synthesize any kind of protein.

The process of transcription by which genetic information stored in the DNA is passed to the RNA, which translate this information to make the protein.

Protein is the final output of the genetic information stored in the organism's cell, if any change in the DNA sequence it affects the final functional structure of the protien.

Therefore, different protein is the result of the base pairs on this strand of DNA being switched.

What are the similarities and differences between plant, animal, and fungal cells?

Answers

Answer:

They are eukaryotic cells, they present the three main parts: cell or cytoplasmic membrane, cytoplasm and nucleus defined with chromosomes and nucleolus. The three types of cells have in common the following structures: cell membrane, cytoplasm, nucleus defined with chromosomes and nucleolus, mitochondria, smooth and rough endoplasmic reticulum, ribosomes, Golgi apparatus, cytoskeleton and peroxisomes. But it differs in some. The plant cell has chloroplasts and a cell wall and the animal cell does not.

Explanation:

The animal cell has centrioles, lysosomes. It has no plastids, no cell wall, it has vesicles. They do not have the ability to produce their own food from inorganic components. The plant cell has plastids (chloroplasts), cell walls, large vacuoles. Fungal cells are organisms without chlorophyll, therefore they cannot photosynthesize. The reserve substances of the cytoplasm are not starch granules. As they are not able to synthesize their food, they have to obtain from other living organisms (they feed on other plant and animal residues contributing to decomposition) that is, they are heterotrophic. Fungal cells have a cell wall that is not present in animal cells and but plant cells have a cell wall. They have lysosomes and centrioles that the plant cell lacks but they are in animal cells. Animal cells, with a few exceptions, do not have vacuoles while plant cells do. The three types of cells have present nucleus, membrane, mitochondria, endoplasmic reticulum, Golgi system.

A woman with Type O blood and a man who is Type AB have are expecting a child. What are the possible blood types of the kid? 2. What are the possible blood types of a child who's parents are both heterozygous for "B" blood type?

Answers

a) The child can only have Type A (50% chance) or Type B (50% chance) because type O is recessive and the man carries no recessive O gene.
b) The child could have a 75% chance of having Type B or a 25% chance of having Type O.

The possible blood type of offspring, when a woman with type O and a man who is type AB are expecting a child are A and B.

What are the types of blood groups?

There are four kinds of blood groups which are A, B, AB, and O, based on the presence of antigens in RBC. Blood groups A and B show co-dominance, while O is recessive.

When a woman with type O blood and a man who is Type AB are expecting a child, the possible blood types are A and B. 50% of the children would have A blood type, and 50% of children would have blood type B, which are heterozygous.

When Parents are both heterozygous for the B blood group, then the possible blood group of offspring would be 75% B blood type (25% are homozygous and 50% are heterozygous) and 25% O blood type.

Impact.

Explanation:

Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments.

In Science, the study of blood is generally referred to as serology.

Impact refers to how fast blood traveled from its source to where it landed.

This ultimately implies that, an impact is a measure of the rate at which blood travels from its source to where it lands. The four (4) phases of impact includes;

I. Displacement.

II. Retraction.

III. Contact and collapse.

IV. Dispersion.

In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.

Generally, the cardiac cycle occurs in two (2) stages;

Diastole : in this stage, the ventricles is relaxed and would be filled with blood.

Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.

Generally, the right atrioventricular valve (AV) is also referred to as the tricuspid valve and is located on the right dorsal side of the human heart. The right atrioventricular valve (AV) comprises of three (3) leaflets (flaps) which opens and closes in order to allow for the flow of blood from the right atrium of the human heart to the right ventricle. Also, the right atrioventricular valve is saddled with the responsibility of preventing blood from flowing backward in the mammalian heart.
