☢ the brain which control and co-ordinate the body of the human being.
↪ the brain is broadly divided into three parts.
➊. cerebrum (fore brain)
➋. midbrain.
➌. hindbrain.
------------------------------------
➊. cerebrum; it is the main part of the brain so it is the faculties of learning reasoning memory, personality, intelligency, thoughts, sensation, action and all voluntary movement.
this part of the brain works according to the receptors. they have both areas such a sensory area and motor areas.
➋. midbrain; this brain controls the cerebral reflex moment. such as the visual auditory stimuli.
➌. hindbrain; it consists into 3 parts such as pons, cerebellum and medulla.
★ pons; Pons located lower part of the brain near the pituitary gland, which regulates the respiration.
★ cerebellum; it maintain the balance of the body. it accurate the movement,also control the smooth movement such as walking, dancing, riding a bicycle etc.
★ modulla: it also located the lower part of the brain which controls the involuntary action such as Heartbeat, breathing,blood circulation, blood pressure, coughing,sneezing etc.

Answer:
True
Explanation:
This is because lymphocyte syndrome is a genetic condition where there is absence of or in ability of the cell to express histocompatibility complex class II or MHC class II and this lead to incapability of the immune system to fight infections. The immune system is compromised and weakened to fight infections.
8 In sexual reproduction, an offspring is produced with genes from both parents. When the offspring has a new genetic variation that it got from neither of its parents, it is called. A. an automotive B. a mutation C. a recessive gene D. a phenotype
Answer: B
Explanation:
Mutations are changes in the DNA sequence that can lead to genetic diversity. Mutations are usually errors in DNA replication or mitosis.
In humans, dimples are dominant to no dimples and freckles are dominant to no freckles. A man with
no dimples or freckles mates with a woman who is heterozygous for both traits. Determine the
percentage of their offspring that will have the same genotype as their mother. Also determine the
percentage of their offspring that will have the same phenotype as their father.
Answer:
I'm being honest the answer are in the pdf pls don't report me its not a scam
Explanation:
The correct answer is 25% of their offspring will have the same genotype as their mother.
25% of their offspring will have the same phenotype as their father.
What is genotype?The term genotype refers to an organism's whole complement of genes; in other words, it describes its genetic composition. In a more restricted meaning, the phrase can refer to the alleles, or alternative forms of a gene, that an organism carries.
what is phenotype?A phenotype is just an observable trait. Pheno means observe and is derived from the same root as "phenomenon." As a result, it's an observable sort of organism that can refer to anything from a common characteristic like height or hair color to the presence or absence of a disease.

HOW, down to an atomic level is the energy in lighting converted from one form to another.
Give 3-5 sentences
PLEASE HURRY
Answer:
When properly stimulated, electrons in these materials move from a lower level of energy up to a higher level of energy and occupy a different orbital. Then, at some point, these higher energy electrons give up their "extra" energy in the form of a photon of light, and fall back down to their original energy level.

A young man claiming to be the son of Howard Hughes is suing the estate for his inheritance. Hughes (multimillionaire, inventor, businessman, and subject of the 2004 film, Aviator), did not leave behind any heirs upon his death. The judge overseeing this case, orders blood tests. Howard Hughes has blood type AB, the mother of the young man has type A blood, and the young man had type O. If you were the judge in this case, what would be your ruling?
Answer:
The young man is not the son of Howard Hughes.
Explanation:
The human blood system works on codominance type of inheritance in the case of blood group A and blood group B present together however, in blood group O it still follows the law of dominance as antigen O is recessive in present of any other antigen.
We know Howard Hughes had blood type AB
So, the genotype would be - IAIB
We also know that the mother of the young man claiming has a blood type A
So, possible genotypes would be - IAIA (case 1) or IAi (case 2)
For case 1,
The possible genotypes for the man claiming would be
IAIB X IAIA --------> IA IA, and IAIB.
According to case 1, he is not the son of Howard.
For case 2,
The possible genotypes for the man claiming would be
IAIB. X I A i ---------> IA IA , IAIB I A i and IB i
Both cases show that the man claiming is not the son of Howard as the blood group of the man is O and the genotype should be ii.

Answer:
- Most animals have the capacity for active movement
- Animal zygotes undergo mitotic divisions called cleavage
- All animals are heterotrophs
Explanation:
Animals, also known as metazoans, are multicellular eukaryotic organisms from the kingdom Animalia. Animals are a monophyletic group, i.e., all animals are derived from a common ancestor. Animals can be classified into two main groups: 1- invertebrates that don't have a backbone inside their body (e.g., earthworms, octopus, snails, insects, etc) and 2-vertebrates that have a backbone inside their body (e.g., fish, amphibians, reptiles, birds, mammals). Cleavage refers to the division of animal cells in the early embryo. In animals, the zygotic cell divides by mitosis (i.e., cleavage), into smaller cells called blastomeres. Some of the most common characteristics of the animal kingdom are:
- heterotrophy: animals cannot produce their own food and obtain energy by feeding organic material present in other organisms
- generally reproduce through sexual reproduction
- animal's cells do not have cell walls
- they are able to move in almost one stage of their lives
- they can respond to external stimuli by nerve cells and/or muscle cells
The most common form of hemophilia is a defect in blood clotting factor VIII, which is caused by a mutant form of a gene on the X chromosome. Boys who inherit that mutation from their mother suffer from uncontrolled bleeding. Girls carrying one copy of this mutation have near normal blood clotting. Uncommonly, a girl is born with hemophilia even though both parents have normal phenotypes. Which of the statements might explain hemophilia in a girl born to parents with normal blood clotting phenotypes?
Answer:
Nondisjunction during sperm arrangement and formation brought about her getting no sex-chromosome from her dad and an X chromosome from her mom, she is XO.
Explanation:
Nondisjunction during sperm arrangement and formation brought about her getting no sex-chromosome from her dad and an X chromosome from her mom; she is XO.
It is on the grounds that her mother happens to be a carrier of hemophilia and she transferred that mutant allele to her daughter and due to the fact that she did not get any sex-chromosome from her dad.
However, such mutant (X) communicates and expresses itself and she is hemophilic.
This (X) is not express in her mother because she possesses a recessive trait; as such it appears in the hom8zygous state.

Explanation:
A mountain range divides a freshwater snail species into two large isolated populations. Erosion eventually lowers the range and brings the two populations together again, but when they mate, the resulting hybrids all produce sterile young. This scenario is an example of:
Answer:
allopatric speciation.
Explanation:
Reproduction can be defined as a biological process which typically involves living organisms producing an offspring.
Basically, there are two (2) methods of reproduction and these are;
I. Sexual reproduction.
II. Asexual reproduction.
In this scenario, a freshwater snail species is divided into two (2) large isolated populations by a mountain range. This range is then lowered by an erosion and as such bringing the two populations of the freshwater snail species together again.
However, when the two snail species mate, the resulting hybrids all produce sterile young snails. Thus, this scenario is an example of allopatric speciation.
Allopatric speciation is also referred to as geographical speciation and it can be defined as a process in which two (2) biological populations of the same species become isolated from each other by geographical barriers or changes such as mountain range, emigration, etc. Thus, allopatric speciation is dominant with living organisms that reproduces sexually and it causes the isolated species to evolve newly with distinctive traits.

What functions does the red blood cell do for a human?
Answer: Red blood cells carry oxygen from our lungs to the rest of our bodies. Then they make the return trip, taking carbon dioxide back to our lungs to be exhaled. The function of the red cell and its hemoglobin is to carry oxygen from the lungs or gills to all the body tissues and to carry carbon dioxide, a waste product of metabolism, to the lungs, where it is excreted.
