the heart must pump more blood to other places of the body
Explanation:
Explanation:
As you exercise energy and oxygen are needed by the muscles to work, therefore the faster you move the quicker your heart beats inorder to supply the muscles you are using with energy and oxygen.
A man with a blood genotype IAi marries a woman with a blood genotype IAi. What phenotypes could be expected in their children? 1. Both type A and type O 2. Type O only 3. Type A only 4.Type B only
Answer:
1. Both type A and type O
Explanation:
Blood genotype in humans follow the ABO system. The allele iA (type A) and iB (type B) are co-dominant but both dominant over the allele i (type O). This means that only a human with two i alleles will be type O.
Type A - iAiA or iAi (heterozygous)
Type B - iBiB or iBi (heterozygous)
Type O - ii
In this question, a man with a blood genotype IAi (type A) marries a woman with a blood genotype IAi (type A). Each of the parents will produce a gametes iA and i. Using these gametes in a punnet square (see attached image), offsprings with the following genotype will be produced: iAiA, iAi, and ii.
iAiA and iAi are type A while ii is type O. This means that both type A and type O could be expected in the children of this cross.

The images show the stages of human development. At which stage does cell differentiation start?
Between the eighth and sixteenth weeks of pregnancy, the human fetal pituitary experiences cellular differentiation.
What is cell differentiation ?The process of cell differentiation is how dividing cells alter their phenotypic or functional type. It is likely that all cells originate from stem cells and acquire their functions as they develop. Stem cells are typically at the top of a hierarchical structure that represents cellular composition.
The transformation of a single-celled zygote into a multicellular embryo and then into the complex multisystem of several cell types that is a fetus is an illustration of cell differentiation.
Gene expression and cell differentiation can both be influenced by environmental variables. Available nutrients, salinity, and temperature, for example, are all elements that can alter gene expression in organisms.

Describe the two negative impacts that deforestation causes concerning greenhouse gases?
Answer:
Without trees the greenhouse gases will affect our health and it will also decrease the amount of oxygen. With deforestation there will be less trees which means less oxygen as well as no shade for when we go hiking, and it will get rid of animal habitats.

A man was diagnosed as suffering from cancer of the white blood cells. Doctors examined his chromosomes and found that chromosomes 9 and 22 were broken and the pieces had swapped places. What kind of chromosomal mutation is this?
translocation
deletion
duplication
inversion
Answer:
the answer is translocations
Explanation:
A reciprocal translocation occurs when two fragments break off from two different chromosomes and swap places.
The type of chromosomal mutation in the given scenario is translocation, the correct option is A.
What is translocation?A genetic transformation that occurs when a piece of one chromosome shatters off and adheres to another. Pieces from two distinct chromosomes will occasionally swap places.
In the given scenario, the chromosome 9 and 22 were broken and swapped, will result in translocation.

To summarize what you have learned about transcription, explain how a gene directs the synthesis of an mRNA molecule. Include in your explanation the words and phrases: base-pairing rules, complementary nucleotides, DNA, gene, mRNA, nucleotide, nucleus, and RNA polymerase
Answer:
Please find a detailed explanation of the process below
Explanation:
Transcription is the first stage of gene expression in living organisms in which a DNA sequence is used to synthesize a mRNA molecule. This process, which occurs in the NUCLEUS of eukaryotes and cytoplasm of prokaryotes, is catalyzed by an enzyme called RNA POLYMERASE.
- In the initial stage called INITIATION, RNA polymerase binds to the promoter of GENE and starts to unwind the double strand of the DNA sequence.
- The RNA polymerase, then, begins to add complementary NUCLEOTIDE bases following the COMPLEMENTARY BASE PAIRING RULE, which states that Adenine will pair with Thymine (Uracil in RNA) while Guanine will pair with Cytosine i.e. T-A, A-U, G-C etc. This stage is called ELONGATION.
- The last stage called TERMINATION involves the stopping of the process because the RNA polymerase has encountered a termination signal.
List and describe three common defense mechanisms. Description is needed.
Answer:
1. Reaction Formation
2. Denial
3. Regression
4 .Acting Out
5. Dissociation
Explanation:
Answer:
hand-to-hand combat
a gun
heavy object (baseball bat or something like that)
Explanation:
I don't know what situation you mean, but if the person is caught off guard, the first defense mechanism is your own body, punches, kicks, stuff like that
If someone is attacking, there's a 50/50 chance that they will have a gun, in that case, the gun can be used on either side, the attacker or the attacked
If someone is attacking, it is also possible that heavy objects, baseball bats, table legs, pipes, are going to be used on either side.

What would happen to the cycling of nutrients, including water, oxygen and carbon
dioxide, if plants died out on Earth?
Answer:
Water would become less used and more abundant, oxygen would be less produced, and carbon dioxide would become more abundant because the plants won't take it in to produce glucose.

Recently, scientific researchers have been delving into how culture and human behavior are affected by our DNA. One field that studies genes is the field of epigenetics. Identify the correct description of what the field of epigenetics studies.
Answer:
the ways in which gene expression is influenced by a person's environment
Explanation:
Epigenetics may be defined as the field of study where one studies about the heritable changes in the gene expression which do not involve the changes in the underlying sequence of the DNA. It literally means above the genomes.
Scientist and researchers have delving into how human behavior and culture are affected by the DNA. Epigenetics is the study that correctly describes the ways in which the gene expressions are influenced by the individual's environment.

Answer:
1. Gravitational potential energy is the energy that an object has because of its height and is equal to the object's mass multiplied by its height multiplied by the gravitational constant (PE = mgh). Gravitational potential energy is greatest at the highest point of a roller coaster and least at the lowest point.
2. Kinetic energy is energy an object has because of its motion and is equal to one-half multiplied by the mass of an object multiplied by its velocity squared (KE = 1/2 mv2). Kinetic energy is greatest at the lowest point of a roller coaster and least at the highest point.
3.Initially, before the big bang, the universe-ball was at rest. Now, after the big bang, it is falling: light and matter exist, and they are moving. And yet, because of the negative energy built into the gravity field created by these particles, the total energy of the universe remains zero.
4. When the temperature of an object increases, the average kinetic energy of its particles increases. When the average kinetic energy of its particles increases, the object's thermal energy increases. Therefore, the thermal energy of an object increases as its temperature increases.
5. When the skater is dropped onto the ramp from above, the potential energy decreases and the kinetic energy increases. Every time the skater bounces from the impact, thermal energy is gained, and both potential and kinetic energy are lost.

explain why cells must divide rather than grow. explain how surface area and volume as well as transport across the cell membrane are related to cell size and homeostasis
Answer:
Cells must divide rather than grow in order to replace damaged cells and reproduce unicellular organisms. The surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. Along with this, cell transport helps cells maintain homeostasis by keeping conditions within normal ranges inside all of an organism's cells.

contained similar fossils. These fossils led them to believe that a temporary land
bridge between South America and Africa allowed ancient species to move
