Answer:
-almost all the cells of your body contain the exact same DNA.
Explanation:
Gene regulation is how a cell controls which genes, out of the many genes in its genome, are “turned on”.
Answer:
Genes are regulated to preserve energy and space.
Explanation:
The process of expressing genes is an energy-requiring process since it requires the breaking and synthesis of proteins. When genes are regulated energy is saved as only the gene required to perform a certain job is turned on and after the function is completed it is turned off. Therefore, continuous protein synthesis is not required to express the genes at all times.If the genes were not regulated i.e., turned off and turned on at required times then it would take a never-ending spree of gene expression which in turn would require a lot of time in transcription and translation.For more information:

Describe how random mutation in an individual can result in a new adaptation in a population.
pls help
Answer:
Errors in the human genetic code, which are called mutations, sometimes lead to the production of abnormal proteins that may cause disease, including autoimmune disease and malignancy.A gene mutation is a permanent alteration in the DNA sequence that makes up a gene, such that the sequence differs from what is found in most people. Mutations range in size; they can affect anywhere from a single DNA building block (base pair) to a large segment of a chromosome that includes multiple genes.

The creation of new crust at the middle of mid-ocean ridges is also
referred to as... *
A.mountain formation
B.sea floor spreading
C.fault formation
D.a transform boundary
Answer:
B.sea floor spreading
Explanation:
The creation of new crusts at the middle of the mid- ocean ridges is also sea floor spreading.
The process of sea floor spreading entails the creation of new crusts at the margin of the oceanic crusts.
Basaltic materials from the subsurface upwells to the surface.
They cool and solidifies to form new crusts. The old crust is moved behind and away from the margin. This way, sea floor is formed and it spreads in like manner.
At this margin sea floor is created and at a convergent margin, it is destroyed.
Which stage of the cell cycle happens directly after cytokinesis?
A
mitosis
B
M phase
C
anaphase
D
interphase
The cell cycle phase that occurs immediately following cytokinesis is the interphase, which is in Option D because the interphase consists of the G1, S, and G2 and is constitutively called the preparatory phase.
What is the cell cycle's importance?The cell cycle consists of the interphase and the division phase, and in the interphase, the cell spends most of the time preparing itself for the cell division and consists of the G1, S, and G2 phases. Following the interphase, the cell enters the division phase, which is mitosis or meiosis, and divides, with the daughter cells potentially entering the cell cycle via the interphase.
Hence, the cell cycle phase that occurs immediately following cytokinesis is the interphase, which is in Option D because the interphase consists of the G1, S, and G2 and is constitutively called the preparatory phase.

The substrate molecules are entering the cells, so no product is made yet As the substrate is used up, the rate decreases (the slope is less steep)
The line is flat because no new substrate remains and thus no new product appears
There is sufficient substrate, so the reaction is proceeding at a maximum rate
Section A Section D
Answer:
The substrate molecules are entering the cells, so no product is made yet.
There is sufficient substrate, so the reaction is proceeding at a maximum rate
As the substrate is used up, the rate decreases (the slope is less steep)
The line is flat because no new substrate remains and thus no new product appears
Explanation:
First the substrate molecules enters in the cell and no product is produced because the reaction is not started yet. When the reaction starts, the substrate is in large amount while on the other hand, the amount of product is low. As the reaction proceed forward, concentration of substrate is lowering and concentration of product is increasing. When all the substrate used up, so no new product is formed.

treatment for PTSD campus be described A.multumodal multi-phasic b. atheoretical C. stress inclusion D.eclectic
Answer:
A. multimodal and multiphasic
Explanation:
Hypnosis can be defined as a mental state that is trance-like and it is typically characterized by minimal peripheral awareness, vivid fantasy, highly focused attention (concentration) and an increased level of suggestibility.
Simply stated, hypnosis is a sleep-like state and as such can be used by psychologist or therapist to reduce the sense of pain, induce relaxation, strengthen certain behaviors etc.
Hence, one of the ways in which hypnosis can be administered by psychologists or therapists is through Hypnotherapy, which typically involves the use of hypnosis in psychotherapy to treat medical conditions such as depression, eating disorders, anxiety, post-traumatic stress disorder (PTSD).
The treatment for post-traumatic stress disorder (PTSD) can be described as multimodal and multiphasic because it is characterized by series of activities and it takes place in various phases.

Explanation:
Genetic variation can occur during meiosis because of the process of ________
1.crossing over
2.cell division
3.fertilization
Answer:
crossing over
Explanation:
During prophase of meiosis I, the double-chromatid homologous pairs of chromosomes cross over with each other and often exchange chromosome segments. This recombination creates genetic diversity by allowing genes from each parent to intermix, resulting in chromosomes with a different genetic complement.
Genetic variation can occur during meiosis because of the process of crossing over.
What do you mean by crossing over?Crossing over is a cellular process that happens during meiosis when chromosomes of the same type are lined up. When two chromosomes one from the mother and one from the father line up, parts of the chromosome can be switched.
Crossing over is an enzyme-mediated process, where the exchange of genetic material between non-sister chromatids of homologous chromosomes takes place. It occurs at the pachytene stage of prophase I of meiosis.
During crossing over, part of one chromosome is exchanged with another. The result is a hybrid chromosome with a unique pattern of genetic material.

O A The offspring can only express the trait of gray body color.
OB. The offspring can only have genes for the trait of gray body color.
O c The offspring can express either the gray or the black body color trait
O 0. The offspring are equally likely to have genes for the gray or black body color trait.
The prediction about the offspring's body color is based on the properties of genetic reproduction, it can only express the trait of gray body color. The correct option is A.
What is the dominant and recessive gene?Recessive and dominant genes. Dominant/recessive interactions are the most frequent type of allele-allele interaction. When one (dominant) allele of a gene effectively outweighs the other (recessive) allele, the allele is said to be dominant.
Blood types and eye color are two instances of dominant/recessive gene interactions. Due to recessive inheritance, the disease can only be brought on by a pair of faulty genes. Carriers are individuals who have only one faulty gene out of the pair.
Therefore, the correct option is A. The offspring can only express the trait of gray body color.

name and describe the two types of food making found among autotrophs and give an example of each. Which is quantitatively more important to life on earth (which are there more of)?
Answer:
See the answer below
Explanation:
Autotrophs are organisms that have the capacity to manufacture their foods from freely available inorganic products. There are two types of autotrophs
1. The photosynthetic autotrophs: these are green plants and blue-green algae that possess chlorophyll. The chlorophyll is used to trap radiation from the sun in the presence of water and carbon dioxide to manufacture carbohydrates which serve as their primary foods.
[tex]6CO_2 + 6H_2O + sunlight --> C_6H_1_2O_6 + 6O_2[/tex]
2. The chemosynthetic autotrophs: these are usually bacteria that make use of energy from inorganic chemicals (such as hydrogen sulphide, iron sulphide, etc) to reduce carbon dioxide and produce carbohydrates in the process.
[tex]CO_2 + 4H_2S + O_2 -> CH_2O + 4S + 3H_2O[/tex]
Photosynthesis is quantitatively more important to life on earth because green plants form the base of several food chains. The energy locked in the carbohydrate produced during photosynthesis is important for other lives in the ecosystem and this is passed on through the various levels in the food chain. Also, the by-product of photosynthesis, the oxygen, is important for the survival of most life on earth who depends on oxygen for respiration. Chemosynthesis only occur in habitats where the radiant energy of the sun is lacking, such as hydrothermal vents.
