The resource that the National Park Service manages is wildlife refuges. Details about wildlife can be found below.
What is wildlife?Wildlife refers to living organisms or animals that are not domesticated and lives in their natural habitat.
In their natural habitats, these wildlife animals are being killed discriminately to the point of extinction.
This led to the development of national park reserves that are responsible for the management and safety of wildlife animals.
Therefore, the resource that the National Park Service manages is wildlife refuges.

The opossum, which is native to North America, and the kangaroo, which is native to Australia, are marsupials.
The fact that both these mammals incubate their immature offspring in a pouch provides evidence that they -
O are descended from a common ancestor
O belong to the same species
O must range great distances to eat
have very similar skeletal structures
Answer:
Belong to the same species
Explanation:
Marsupials carry their young in "pouches", and are therefore related to other marsupials, like the kangaroo, opossum, wombats, and koala to name a few.
The opossum is a native of North America as the kangaroo is a native to Australia and both of them are mammals thus boh belong to the same specie. Thus option B is correct.
What are mammals?A mammal is an animal that is warm-blooded and has hair, vertebrates, and backbone. These creatures share human relations and produce milk for their young ones. The kangaroo is like an opossum that is marsupials carry their young in "pouches".

Answer:

Explanation:
Write this!
If you were to place a seed down horizontally, the roots and the shoot will be grown horizontally, but when the plant grows, it will slowey become less horizontal as time flies by and shape back into a straight manner towards the sunlight, this would be a example of a term known as geotropism (the response of plants from gravity).
A mutation that could be inherited by offspring would result from-?
Answer: Along with substitutions, mutations can also be caused by insertions, deletions, or duplications of DNA sequences. Some mutations are hereditary because they are passed down to an offspring from a parent carrying a mutation through the germ line, meaning through an egg or sperm cell carrying the mutation.
Explanation:
A mutation that could be inherited by offspring would leads from a base substitution in gametes during meiosis. The correct option is D.
What is mutation?Any alteration to a cell's DNA sequence. Alterations in cell division can result in specific mutations.
As can exposure to environmental DNA-damaging substances. Mutations may be negative, positive, or ineffective.
Errors in DNA replication during cell division, exposure to mutagens, or viral infection can all cause mutations.
Somatic mutations (which happen in body cells) cannot be passed on to offspring, whereas germline mutations (which happen in eggs and sperm) can.
A base substitution in gametes during meiosis would result in a mutation that might be passed on to progeny.
Thus, the correct option is D.

A biologist pollinates a true-breeding yellow flower with pollen from a true-breeding red flower of the same species. All of the F1 offspring are yellow. What question can be answered with the F2 cross?
Answer:
See the answer below
Explanation:
The question that can be answered with the F2 cross would be if the yellow flower color is dominant over the red flower color in the species. In other words, whether the inheritance of flower color follows a simple Mendelian inheritance or otherwise can be answered.
Assuming that the inheritance of the flower color follows the Mendelian pattern, the red flower trait would re-emerge among the F2 offspring and the ratio of yellow to red flower offspring would approximately be equal to 3:1. Otherwise, a more complex pattern of inheritance would be involved.

Artificial selection has produced a wide variety of crop plants, livestock, and pets. Which characteristic of artificial selection makes it different from natural selection
Answer:
Genetic Problems
Explanation:
When people genetically modify animals, they can mess up a lot of their natural abilities. For example in some cases scientist have made cows who produce more milk, but couldn't reproduce anymore because of it. Sometimes it even hurts the animal. People have bred dogs in certain ways that makes it hard for them to breathe, like Bull dogs who has respiratory issues. This makes decreases their life span and continuing to bred them will only make it worse. When scientist have a certain trait they want they also make animals breed with their own families. Incest creates a lot of genetic problems.

The components that make up the genetic code are common to all organisms. If a segment of a gene contains 27 nucleotides, none of which are stop or starts codons, how many amino acids does this segment code for?
Answer:
9 amino acids
Explanation:
A segment of a gene that has 27 nucleotides will code for 9 amino acids.
Each codon on the gene potentially represents an amino acid and a codon is made up of 3 nucleotides each. Hence, in order to find out the total number of amino acids that a gene segment with 27 nucleotides can code for, the number of nucleotides should be divided by 3.
number of amino acids = number of nucleotides/3
27/3 = 9 codons/amino acids

If more individuals are born with the advantageous trait in each generation, over time what do you predict will happen to the percentage (%) of the alleles (gene variety) that code for this trait in the population?
Answer:
The percentage (%) of the alleles that code for this trait in the population will increase, as more individuals are born with the trait.
Explanation:
The more individuals get born expressing the trait, the higher its frequency gets in the population. By generation, there are more individuals carrying the allele for the advantageous trait. These individuals reproduce and increase the probabilities of the progeny to inherit the mentioned allele. When this sequence keeps occurring in the population over many generations, the allele percentage will increase. On the other hand, the other allele or alleles will decrease. Probably, if there are no changes that might influence or affect this pattern, the alleles for the advantageous trait will fixate, while the other allele might get lost.
What is an advantage of this type of reproduction? A. It allows a species to avoid harmful mutations. B. It enables a species to increase its genetic variability. C. It allows a species to withstand long periods of unstable environmental conditions. D. It enables a species to rapidly populate an environment that has favorable conditions.

How does a plant cell differ from an animal cell? Group of answer choices A plant cell can make its own glucose; an animal cell cannot A plant cell cannot synthesize proteins an animal cell can. A plat cell cannot perform cellular respiration; an animal cell can.
Answer:
plant cell can make its own glucose; an animal cell cannot
Explanation:
Chloroplasts are found in plant cells, but not in animal cells. The purpose of the chloroplast is to make glucose that feed the cell's machinery. Photosynthesis is the process of a plant taking energy from the Sun and creating glucose.
Photosynthesis uses energy from the Sun to make sugars such as glucose. What has to happen to the glucose before it can be used by plant cells?
A The glucose combines with another sugar to make usable energy.
B The glucose combines with oxygen to make usable energy.
OC The glucose combines with carbon dioxide to make usable energy.
OD Nothing has to happen to the glucose. Plant cells can use it as is.
Answer:
Respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce useable cellular energy. This energy is used to fuel growth and all of the normal cellular functions.
D Nothing has to happen to the glucose. Plant cells can use it as is.
What happens to the glucose produced by plants?Glucose produced by photosynthesis is a simple sugar that is used by plant cells as a source of energy and as a building block for other organic compounds. The glucose can be transported within the plant and used directly by cells as a source of energy through cellular respiration.
In cellular respiration, glucose is combined with oxygen to release energy in the form of ATP (adenosine triphosphate), which is used to fuel various cellular processes. So, there is no need for glucose to undergo any additional chemical reactions before it can be used by plant cells.
