Answer:
Adaptations develop from variations within a population and help organisms to survive in their given environment. Changes in populations accumulate over time; this is called evolution. The fossil record shows us that present-day life forms evolved from earlier different life forms.

This core has stayed hot over the billions of years since. Every kilometer you go down, it gets about 25 degrees Celsius hotter (or 1 degree Fahrenheit per 70 feet). The core will never freez
over. Scientists estimate it would take about 91 billion years for the core to completely solidify. The sun will burn out long before that time!

(A) guess; freeze
(B) hope; set
(C) predict: harden
(D) assume, congeal
Answer:
C. Predict; Harden

30. Which substance would most likely be in the cell
walls of an organism with chloroplasts and tissues?
A. peptidoglycan
C. hyphae
B. chitin
D. cellulose
Answer:
D. cellulose
Explanation:
:>
An organism having chloroplasts and tissues most likely has cellulose in its cell walls.
The correct answer is D
Simply put, what is cellulose?a complex carbohydrate that is the main component of plant cell walls and is typically obtained as a white stringy substance from plant matter (such as wood or cotton) that is used in the production of various products (such as rayon and paper). Another way to say this is that cellulose comes from plants.
Where does cellulose come from?A carbohydrate called cellulose is present in plant cell walls. A polysaccharide structure makes up the carbohydrate. Several sugar molecules are linked together chemically to form a lengthy chain known as a polysaccharide. Chitin, glycogen, cellulose, and starch are a few examples of polysaccharides.

Marine biotechnology can be used to produce genetically modified (GM) fish with preferred traits. Some opponents of genetic modification argue that the release of these fish can have a negative impact on natural ecosystems. Is this a valid concern, and can anything be done to minimize the impact on nature
Incomplete question. The options;
a) yes, gm fish could alter biodiversity if they mate with fish in the wild. This impact is best minimized by producing gm fish that are sterile.
b) yes, gm fish can alter biodiversity if they mate with fish in the wild. This impact is best minimized by tracking the released fish and capturing them.
c) no, gm fish cannot impact natural ecosystems because they are likely to die in the wild. There is no need to be concerned about the impact to nature.
d) no, gm fish cannot impact natural ecosystems because they are designed.
e) there is no need to be concerned about the impact to nature.
Answer:
a) yes, gm fish could alter biodiversity if they mate with fish in the wild. This impact is best minimized by producing gm fish that are sterile.
Explanation:
Indeed, genetically modified (GM) fish basically refers to fish whose natural traits have been edited or adjusted by scientists. For example, they may be modified in such a way that they feed more and grow faster than is usual for wild fish. Biodiversity is altered when these GM fish begin to consume more food and also producing offsprings with similar traits, over time this would make it difficult for natural wild fishes to find food; reducing their population, thereby impacting nature.
However, if GM fish are produced to be sterile (ie cannot reproduce offsprings), it could easily lead to a balance in the population of the natural ecosystem.

Which of the following is not a function of the cell membrane?
Answer:
The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.
Explanation:
This is what the cell membrane does so if any of these are an answer choice then use process of elimination to figure out which one is correct

Complete the Punnett square below by showing the genetic makeup of the parent plats of the cross shown.Be sure to show both genes for each parent.
Answer:
The correct answer is -
Parent 1: RW, Parent 2: RR
Explanation:
In the given punnet square there are four offspring and it is a monohybrid cross between parent 1 and parent 2. The four offspring produced in this cross have RR, RR, RW, and RW alleles. By the genotype of the offsprings, it is clear that there are 50 percent pure or true-bred and 50 percent are heterozygous.
Each parent contribute two alleles and these alleles are independently assort in the zygote to form offspring so there must be R, R, R and W allele present in the parent
Parent 2 → R R
Parent 1 ↓ R RR RR (one allele (R) come from each parent in zygote)
W RW RW (one allele (R and W) come from each parent)

Answer:
i would say B
Explanation:
Fossils can tell us about the size depending on how large the bones are. The year of death could possibly be determined by the way the bones look maybe, same with the environment, showing what type of animal; it could be a type of fish. But I believe there is no way fossils could show the diet and behavior of the animal.

give two functions of pericardium embrane
Understanding the Pericardium (Pericardial Sac) Your heart is surrounded by a double-layered membrane, called the pericardium or pericardial sac. This membrane keeps your heart in place in your chest cavity, restricts the expansion of your heart when your blood volume increases, and helps to protect your heart
Answer:
The pericardium acts as mechanical protection for the heart and big vessels, and a lubrication to reduce friction between the heart and the surrounding structures. A very important role in all aspects of pericardial functions is played by mesothelial cells.
