When is stress actually a good thing? What turns “good” stress into “toxic” or chronic stress
Explanation:
TOXIC- stress is the strong unrelievd activation of the body's stress management system in the absense of the buffering protection of adult support.In preparing a karyotype, a blood sample is centrifuged to separate the blood cells from the plasma. The plasma is discarded and a hypotonic solution is added to make the cells swell. The solution is centrifuged again. A drop of this material is added to a slide, dried, and stained. The slide is viewed and photographed.
Based on this procedure, where is the best place to discard plasma?
A.
In a laboratory sink
B.
In the trash can
C.
In a trash bin marked biohazardous material
D.

The answer is C
Explanation:
1. What is vestigial structure?
2. What is analogous structure?
3. What is homologous structure?
Answer:
1. What is vestigial structure?
Vestigial structures are structures that have no obvious purpose and appear to be leftover components from a previous progenitor. The human appendix, a snake's pelvic bone, and the wings of flightless birds are all examples of vestigial features.
2. What is analogous structure?
Analogous structures are characteristics of various species that are comparable in function but not necessarily in form, do not come from a shared ancestral feature (in contrast to homologous structures), and evolved in response to a similar environmental challenge.
3. What is homologous structure?
Homologous structures are physical traits that are comparable in species with a common ancestry but perform radically distinct purposes. The limbs of humans, cats, whales, and bats are examples of homologous structures.
3. What type of chemical bond forms between positive and negative ions?
Answer:
Forming an Ionic Bond
Once the oppositely charged ions form, they are attracted by their positive and negative charges and form an ionic compound. Ionic bonds are also formed when there is a large electronegativity difference between two atoms.

1) List at least 5 things that lead to variation.
2) Fill out the table below:
Variation Explain Example
Mutation
Gene Flow
Genetic Recombination
3) What are the three types of natural selection? Explain each.
Answer:
1. a.mutation,
b. recombination,
c. immigration of genes,
d.climate and
e.associations
2. Mutation : Is the changing of the structure of a gene, resulting in a variant form that may be transmitted to subsequent generations, caused by the alteration of single base units in DNA, or the deletion, insertion, or rearrangement of larger sections of genes or chromosomes.
Gene flow : Gene flow is also called gene migration. Gene flow is the transfer of genetic material from one population to another. Gene flow can take place between two populations of the same species through migration, and is mediated by reproduction and vertical gene transfer from parent to offspring.Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).Genetic Recombination : Is a process by which pieces of DNA are broken and recombined to produce new combinations of alleles. This recombination process creates genetic diversity at the level of genes that reflects differences in the DNA sequences of different organisms.
3. The 3 Types of Natural Selection
Stabilizing Selection.Directional Selection.Disruptive Selection.Stabilizing selection : Stabilizing selection is a type of natural selection in which the population mean stabilizes on a particular non-extreme trait value. This is thought to be the most common mechanism of action for natural selection because most traits do not appear to change drastically over time. Directional Selection: In population genetics, directional selection, is a mode of negative natural selection in which an extreme phenotype is favored over other phenotypes, causing the allele frequency to shift over time in the direction of that phenotype.Disruptive selection : Disruptive selection, also called diversifying selection, describes changes in population genetics in which extreme values for a trait are favored over intermediate values. In this case, the variance of the trait increases and the population is divided into two distinct groups.How are proteins synthesized by dna through rna
Answer:
During transcription, the enzyme RNA polymerase (green) uses DNA as a template to produce a pre-mRNA transcript (pink). The pre-mRNA is processed to form a mature mRNA molecule that can be translated to build the protein molecule (polypeptide) encoded by the original gene.

Animals inherit traits from their parents. They pass some of these sare traits on to their children,
Suppose a pair of animals has a trait that helps them survive in their environment. They pass this trait on to their children What
effect will that probably have on the children?
A. The children will be more likely to survive than if they did not have the trait
B. The children will be able to adapt if the environment changes.
C. The children will be more likely to survive than their parents were
D. It will not affect the children
Answer:
A)
Explanation:
Heredity is a process in which organisms acquire characteristics from their parents. These characteristics are called traits. Every individual is unique because they have a unique set of traits. The traits which are transmitted by the parent to its offspring during the process of fertilization are inherited traits. This inheritance is determined by certain rules of heredity. Inherited traits are coded in our DNA and hence can be passed on to the next generation.
What sort of information can you get from a body fossil that you can't get from a trace fossil?
Trace fossils include footprints, trails, burrows, feeding marks, and resting marks. Trace fossils provide information about the organism that is not revealed by body fossils. Trace fossils are formed when an organism makes a mark in mud or sand.

what is testis and wnat is overy how zygote form
Answer: hope this helps u
Explanation:
One of two egg-shaped glands inside the scrotum that produce sperm and male hormones is called testis.
One of a pair of female glands in which the eggs form and the female hormones estrogen and progesterone are made.
A zygote forms when a sperm penetrates the outer surface of an egg.
The ovary produces female gametes called ova and the testes produce male gametes called sperms.
The fusion of ovum and sperm is called fertilisation. The fertilised egg is called a zygote.

How do
plants capture light energy?
Answer:
In most plants, the leaves are the main food factories. They capture the sun's energy with the help of chlorophyll in the leaf cells. The chlorophyll traps and packages the energy from the light of the sun in a process called photosynthesis. Leaves usually have a large surface so they can collect the most sunlight.
