Answer:
Energy stems from the sun
Explanation:
Think about it, A plant takes energy from the sun and then a worm eats it soon after a bird eats that worm then when the bird dies its body is fed to fungi or back to plant life. Pretty much the sun is our biggest source of energy
Also The sun is our major source of heat without the sun we would freeze and perish.

The statements that accurately describe how MRSA strains occurred are: Individuals that are admitted to the hospital are likely already carrying MRSA infections. Hospital systems provide a mechanism for extreme selection pressure with sterile technique and heavy use of antibiotics. The correct options are A, C, and D.
These claims draw attention to crucial elements involved in the emergence and dissemination of MRSA strains.
It is possible for someone to carry MRSA before entering a hospital, increasing the likelihood that an infection would take place there (Statement A).
Hospital systems, with their emphasis on sterile procedures and heavy reliance on antibiotics, produce a setting with high selection pressure that favours the survival and spread of MRSA strains (Statement C).
Staphylococcus aureus can also pass on genetic elements that are resistant to methicillin to offspring and other population members, aiding in the propagation of resistant strains (Statement D).
Thus, the correct options are A, C, and D.

The controversy over the ivory-billed woodpecker has pitted those who want to build a massive irrigation project against environmentalists who want to stop the project to protect the woodpecker and other species. A biocentric species egalitarian would probably insist that the a. project be stopped to protect the ivory-billed woodpecker and all the other species of plants and animals. b. project be completed to maximize the welfare of humans. c. project be completed but with rigid safeguards to protect all sentient beings. d. project be curtailed (but not stopped) to promote the interests of humans and the ivory-billed woodpecker only.
ANSWER:
(A) project be stopped to protect the ivory-billed woodpecker and all the other species of plants and animals.
EXPLANATION:
Option A (project be stopped to protect the ivory-billed woodpecker and all the other species of plants and animals) is most appropriate for a biocentric species egalitarian, because it provides equal rights and support for all forms of life without being baised on favoring sentient animals (animals who can feel and can be emotional).
NOTE: Species egalitarianism is the philosophic view that all living things have the same moral right and support and all forms of life have intrinsic value.

For a certain breed of cat, short tails are dominant (1) and long tails are
recessive (1). The Punnett square below shows a cross between two parents,
What is the phenotype ratio for this cross?
T
t
Tt to
TE
A 4 long. O short
B. 2 long, 2 short
C. 3 long, 1 short
D. I long, 3 short
The phenotype ratio for the cross would be 1 long:3 short.
PhenotypesThis refers to the physical expression of genes.
Let us assume that the allele for short tail is T while that of long tail is t.
Since short tails are dominant over long tails, any genotype with T will always be expressed as short tail.
Thus, TT and 2Tt will have short tails while only tt will have a long tail, making a ratio of 3:1.

Explanation:
Which statement is true of meiosis?
A. Organisms use meiosis to repair damaged cells.
B. Organisms use meiosis to grow.
C. Organisms use meiosis to make reproductive cells.
D. Organisms use meiosis to replace blood cells.
Answer:
C. Organisms use meiosis to make reproductive cells.
The statement 'organisms use meiosis to make reproductive cells' is TRUE of meiosis (Option C).
Meiosis is a type of reductional cell division by which a parental cell produces four (4) daughter cells having half of the genetic material.Organisms of sexual reproduction use this type of cell division to produce germinal (gametes) sex cells.During fertilization, two germinal gametic cells fuse to produce a cell (zygote) with a normal amount of chromosomes.In conclusion, the statement 'organisms use meiosis to make reproductive cells' is TRUE of meiosis (Option C).

3. Blood types: House elves have the same basic blood
types that human have; A,B, AB and O.
a. If a male house elf with blood type o has children with a female house elf
who is blood type
AB, what will the phenotypic ratios of their offspring be? (show your work).
b. A male house elf with blood type A (but whose mother was blood type O) has
children with a female elf who is type B (whose mother was type A and whose father
was type AB). What percentage of their offspring should be blood type B?
c. Dobby is blood type A and Harry Potter is blood type AB. Is it possible for Dobby to give
blood to his master? Can Harry give blood to Dobby? Explain.
Answer:
a. 1:1
b. 25%
c. Dobby can give blood to Harry, but Harry cannot give blood to Dobby.
Explanation:
a. Type O blood is recessive to type A blood and type B blood.
A B
O AO BO
O AO BO
According to the Punnett square, 50% of the offspring will have the AO genotype and 50% will have the BO genotype (1/2=50%). This means 50% will have type A blood and 50% will have type B blood, as the alleles for type A and type B blood are dominant over the allele for type O blood.
b. The male house elf's genotype is AO. If his mother was type O, then she only had the type O alleles to pass down to him, so he had to inherit one. The female house elf's genotype is BO. Her mother had to have the genotype AO. This is the only way the female would have inherited type B blood. If her mother had the AA genotype, then she would've had type AA or AB blood.
B O
A AB AO
O BO OO
According to the Punnett square, their offspring have a 25% chance of displaying any of the four blood types (1/4=25%).
c. Dobby has type A blood and Harry has type AB blood. This means that Dobby can give blood to Harry, as Harry has A antigens. However, Harry cannot give to Dobby because Dobby doesn't have B antigens, so he would experience an incompatibility reaction.

Isabella liked to sunbathe. However, after she learned that ultraviolet rays are a cause of environmental mutations, she decided to stop sunbathing When can an acquired mutation be passed from parent to offspring? O A only if the mutation occurs in the sex cells B. only if the mutation occurs in the y-chromosome C. only if the parent has an acquired mutation in the autosomal chromosome D. only if both parents do not have the mutation in the sex cells
Answer:
O A only if the mutation occurs in the sex cells
Explanation:
Mutations can be defined as genetic changes that occur in the DNA sequence of the genome of an organism. Mutations can be classified into two main types: 1-somatic mutations, which occur in somatic cells that form the body of the organism, and 2-germ-line mutations, which occur in sex cells or gametes (i.e., egg and sperm cells). Only germ-line mutations can be passed on to offspring and it occurs when a mutated gamete (either a sperm or an egg) comes together to form a diploid (2n) zygote.
One of the deadliest animals on earth is the rough skinned newt. It produces highly toxic skin toxins. In the 1970s, three hunters were found dead while camping in Western Oregon when they accidentally boiled a rough skinned newt in their coffee pot. Scientists discovered that they were becoming more toxic due to a common predator: the garter snake. As garter snakes were growing more immune to their toxins, rough skinned newts were growing more toxic in what is known as an “evolutionary arms race”.
Though the genes for the garter snake immunity are most likely polygenic, however, let us assume that the immunity is caused by a single dominant allele for this exercise. Those without the dominant gene (the recessive genotype), are NOT immune to the toxins of the rough skinned newt.
In 1975, in a population of 88 garter snakes on the coast of Oregon, 54 of them exhibit the recessive genotype are therefore not immune to the rough skinned newt’s toxin.
