1. Explain why fossil evidence is consistent
with the scientific theory of evolution. sc.7.L.15.1
Answers
Explanation:
The Fossil Record
Fossils of the simplest organisms are found in the oldest rocks, and fossils of more complex organisms in the newest rocks. This supports Darwin's theory of evolution, which states that simple life forms gradually evolved into more complex ones.
Evidence for early forms of life comes from fossils.

In the late 1800s, a biologist studying animal embryos coined the phrase "ontogeny recapitulates phylogeny," meaning that the physical development of an animal embryo (ontogeny) seemed to retrace the changing form of the species during its evolutionary history (phylogeny).
Why would embryonic development retrace evolutionary steps?
Answers
Answer:
Embryo provides information about their ancestors.
Explanation:
Embryonic development retrace evolutionary steps because embryo provides evidence for evolution as embryo formation in widely-divergent groups of organisms are conserved. This embryo provides information that leads to their ancestors from which they evolve so we can say that embryonic development provides evidence for evolution of an organism.

1. How does your DNA differ from other peoples?how is it similar
2.How does your DNA differ from a strawberries DNA? How is it similar
Answers
Answer:
1.DNA is more than 99% similar between any two people. All the differences in how we look, feel, behave and the differences in our health are due to less than 1% difference
2.In humans each of these cells have 2 copies of the DNA, but in strawberries each of these have 8 copies of the DNA that means strawberries have 4 times as many copies of DNA as humans, making it 4 times easier to see.

Two genes are hypothesized to be linked. The map distance between the genes is thought to be 12 map units. Out of 1000 offspring produced by two heterozygous parents, predict how many would occur in each phenotypic category.
Answers
Answer:
Approximately the number of individuals with each phenotype is:
RS-->0.75 x 1000 = 750rs--> 0.19 x 1000 = 190Rs--> 0.05 x 1000 = 50rS--> 0.05 x 1000 = 50Explanation:
Available data:
Two genes are hypothesized to be linkedThe map distance between the genes is thought to be 12 map units. Two heterozygous parents1000 offspring producedLet us say that the two diallelic genes are R (alleles R and r) and S (alleles S and s)
Heterozygous parents might have the following genotype RS / rs
We know that there are 12mp between genes, which means that the recombination frequency equals 0.12 or 12%.
0.12 of the gametes are recombinants and 0.88 are parentals. There are two types of parentals and two types of recombinant, so 0.06 + 0.06 are recombinants while 0.44 + 0.44 are parentals. This is:
Cross:
Parentals) RS/rs x RS/rs
Gametes) RS (parental) 0.44
rs (parental) 0.44
Rs (Recombinant) 0.06
rS (Recombinant) 0.06

F1) Genotypes:
1 RS/RS --> 0.44x 0.44 = 0.1936 2 RS/rs --> 0.44x 0.44 = 0.1936 x2 = 0.38722 RS/Rs --> 0.44 x 0.06 = 0.264 x 2 = 0.0532 RS/rS --> 0.44 x 0.06 = 0.264 x 2 = 0.0531 rs/rs --> 0.44x 0.44 = 0.1936 2 rs/Rs --> 0.44 x 0.06 = 0.264 x 2 = 0.0532 rS/rs --> 0.44 x 0.06 = 0.264 x 2 = 0.0531 rS/rS --> 0.06 x 0.06 = 0.00361 Rs/Rs --> 0.06 x 0.06 = 0.00362 Rs/rS --> 0.06 x 0.06 = 0.0036 x 2 = 0.0072Phenotypes:

RS-->0.75 x 1000 = 750rs--> 0.19 x 1000 = 190Rs--> 0.05 x 1000 = 50rS--> 0.05 x 1000 = 50For this cell division, you can see that 4 daughter cells are made that have half the genetic information as the original. What type of cell division is this?
a) Diffusion
b) Mitosis
c) Meiosis
d) Photosynthesis
Answers
Answer:
The cell division where 4 daughter cells with half of the genetic information of the original are obtained is meiosis (option c).
Explanation:
Meiosis is a type of cell division through which sex cells or gametes are obtained. It is a reductive division, since the daughter cells resulting from the process contain half of the chromosomal charge with respect to the original one.
In the process of meiosis, four haploid cells are obtained from a diploid cell, each of which is involved in the reproduction of the species. This mechanism of division occurs in two stages, called meiosis I and II.
The other options are not correct because:
a) Diffusion: it is a passive trans-membrane transport mechanism.
b) Mitosis: is the cellular division of somatic cells, where the result is two daughter cells identical to the original.
d) Photosynthesis: is the mechanism by which plants obtain energy and nutrients, from solar energy.

Coal-fired power plants

Explain what the greenhouse effect is, use diagrams if you wish.
Include:
-Radiation from the sun absorbs earths heat
-Some emitted
-Trapped by the greenhouse
Answers
Answer:
See the answer below
Explanation:
The greenhouse effect refers to the heating effects produced by the earth's atmosphere on the planet as a result of the atmosphere absorbing reflected radiation from the sun by the earth.
The earth's atmosphere is a blanket of gases, some of which are referred to as greenhouse gases. These gases have the capacity to trap radiations coming from the sun that is reflected by the ground layer of the earth. Thus, they produce a warming effect on the earth.
A bulk of the radiation coming from the sun is reflected back into space by the earth's stratosphere. The small percentage that passes through are dispersed in different directions and some of them pass through the atmospheric blanket to reach the ground layer of the earth. While some are absorbed by the ground itself, some are emitted back into the atmosphere where the greenhouse gases trap a large portion and prevent them from escaping back into space.
This leads to the warming of the earth and the entire phenomenon is referred to as the greenhouse effect.
Dr. Sanchez and her team have observed an unusual star in the Andromeda galaxy. Their data suggests that the star is being consumed by a nearby black hole. They write a scientific paper about their work and submit it to a scientific journal. Other scientists read their paper and look for the unusual star as well. The other scientists are participating in which activity?
Answers
Answer:
so the answer is peer review
Explanation:
Yes, other scientists are participating in this activity not in a direct way but in an indirect way. The scientists are participating in peer review.
What is galaxy?The scientific paper was written by scientists which provide the data and conclusion of entire experiments. To write scientific experiments we need to collect data, frame hypotheses, research methodology, and find out the conclusion are some of the steps to writing a scientific paper.
Testing hypotheses often involves designing experiments. In the given experiment Dr. Sanchez found that star is consumed by a nearby blackhole. But other scientist found the unusual star as well.
This suggests that both scientist thought on different aspect. This suggest peer review.
Therefore, Yes, other scientists are participating in this activity not in a direct way but in an indirect way.

Examples of stimuli are the strong smell of a woman's perfume, the sour taste of a lemon, pinching your skin, dimming the lights in a room, and having your back massaged. The correct options are a, b, c, d, and e.
What are stimuli?Humoral stimuli, hormonal stimuli, and neurological stimuli are the three basic types of stimuli that cause the endocrine glands to produce and release hormones.
With changes in the concentration of extracellular fluids, the humoral stimulus governs hormone release.
The strong smell stimuli the sense organs and sour taste stimuli our tongue and pinching in the skin gives stimuli to obtain that someone pinched pour skin
The neural stimuli allow hormone production straight from the glands.
