Answer:
The mechanism that Darwin proposed for evolution is natural selection. Because resources are limited in nature, organisms with heritable traits that favor survival and reproduction will tend to leave more offspring than their peers, causing the traits to increase in frequency over generations.

Why does the crab and the centipede share the same phylum ?
Answer:
An arthropod is an invertebrate animal having an exoskeleton like a crab and a centipede.
Answer:
They are both invertebrates (without backbones) and belong to the largest phylum in the Animal Kingdom which also includes insects, spiders, crabs, lobsters, etc. They both have one pair of antennae, many pairs of legs, and breathe through little holes or spiracles on the sides of their bodies.
Explanation:
What else do you think plants may need to grow and go through their normal processes?
Plants need water, oxygen, soil, and solar energy.
Those are the only things that I believe plants need. They need water for food and Solar Energy (basically Vitamin D which you get from the sun) and soil to grow. Obviously they need oxygen to be able to survive.

Two species of fish are introduced to the same lake. Over time, only one species survives. According to Darwin's theory of evolution, what should characterize the surviving species
Answer: Both species must have competed for the same niche. The surviving species is better adapted or adapted better and outcompeted the other.
Explanation:
According to Darwin's theory of evolution (survival of the fittest), the surviving species would be fitter than the extinct fish.
What is the theory of survival of the fittest?Charles Darwin proposed the idea of the "survival of the fittest," which states that organisms that are most adapted to their environment have a higher chance of surviving and reproducing. Charles Darwin proposed natural selection as a crucial aspect of evolution.
Natural selection refers to the process by which an organism becomes more likely to thrive and produce more offspring the better it is able to get food and avoid becoming prey. The process of evolution is driven by this "survival of the fittest," which results in species surviving as a whole.
Thus, according to Darwin's theory of evolution, the surviving species would be fitter than the extinct fish.

The immune system has two modalities, specific and nonspecific responses. Which of the following is an example of a nonspecific response?
A. an antigen binding to an antibody
B. inflammation at the site of an infection
C. a cytotoxic T cell attacking a pathogenic agent
D. lymphocytes activating plasma cells in the blood
B. Inflammation at the site of an infection is an example of a nonspecific response of the immune system.
What is non-specific immune response?Non-specific immune responses, also known as innate immunity, are the first line of defense against invading pathogens and are activated immediately upon exposure to a foreign invader. These responses are not specific to a particular pathogen and do not require previous exposure or recognition. Instead, they provide a general response that helps to prevent the spread of the pathogen and contains it until the specific adaptive immune response can be activated.
Examples of non-specific immune responses include physical barriers such as skin and mucous membranes, as well as physiological responses such as inflammation, fever, and the activity of phagocytic cells like macrophages, which engulf and destroy pathogens. Non-specific immune responses also include natural killer cells, which are able to recognize and kill infected cells, and the complement system, a group of proteins that help to enhance the ability of other components of the immune system to destroy pathogens.

A plant can have green (G) or yellow (g) leaves. It can also have a long (K) or
short (k) stem. A scientist is preparing a Punnett square for a dihybrid cross
of a plant with a genotype GgKk. What possible gametes can the plant
produce?
O A. GK, GG, KK, kK
OB. GK, Gk
Oc. GK, Gk, gk, gk
OD. GK, gk
Answer:
The options are incomplete, however, the question can still be answered based on general understanding. The possible gametes are:
GK, Gk, gK and gk
Explanation:
This question involved two different genes coding for leaf color and stem length respectively. In the first gene, the allele for green color is 'G' while the allele for yellow color is 'g'. In the second gene, the allele for long stem is 'K' while the allele for short stem is 'k'.
According to this question, a scientist is preparing a Punnett square for a dihybrid cross of a plant with a genotype GgKk. Based on Mendel's law of SEGREGATION, this plant with genotype: GgKk will undergo meiosis where the alleles of each gene will separate into possible gametes as follows:
GK, Gk, gK and gk
Note that, only one allele of each gene is present in each gamete.
Which feature do highland climates have that lower elevation areas do not?
O a tundra where there are no trees
O a treeline beyond which tree do not grow
O permafrost, or a part of the ground that is permanently frozen
O an ice cap, or a permanent cover of ice and snow
Answer:
a treeline beyond which tree do not grow
Explanation:
The harsh climate conditions do not allow for trees to grow beyond the treeline. The temperature decreases at high altitudes and it is too cold for plants to grow. It is also windier at higher altitudes and there is less water (drains downward toward lower altitudes). These things make it tough for plants to grow.

Nerve impulses are carried to another part of the body by a neuron’s:
(1) dendrites
(2) axon
(3) synapse
(4) neurotransmitter
Answer:
1.
Explanation:
Dendrites is the neuron's that receives nerve impulses and carry it to another part of the body.
Nerve impulses are the messages that are transferred from one part of the body to the another. These messages are carried across the body with the help of neuron's named dendrites.
Dendrites are branched like projections of in the nerve cell. Through these projections, message passes across the body.
Therefore, option 1 is correct.

B. Addressing possible risks to fish before testing a new pesticide
C. Taking blood samples from patients for research purposes
without consent
O D. Using the fewest animals necessary for an experiment
Answer:
C. Taking blood samples from patients for research purposes
without consent
Explanation:
Generally, providers may not render medical services without the patient’s consent, unless performance of emergency, lifesaving care is necessary. Taking samples from a patient is a type of medical service; thus, state consent laws apply. In addition, providers may not disclose PHI without patient authorization.

Will give brainliest If you increase the rainfall across the region that the Buffalo are in, how do you think that would affect the carrying capacity for Buffalo in the ecosystem?
Answer:
The Buffalos carrying capacity would most likely go down if the water supply increases.
Explanation:
If water supply increases Buffalos would have easier access to water. example: instead of getting new water every month or so when it rained they can get water anytime due to the increased supply.
The "Buffalos-carrying" capacity would most likely go down" if, the water supply increases," If water supply increases Buffalos would have easier access to water".
Did a change in temperature cause the buffalo population to increase?Buffalo does shift in regard to the environment because if the climate impacts the carrying-capacity, by involving the resources.
If "the carrying-capacity goes up or down then the people of buffalos would up or down "with it. Although it does not impact the population much.

Why do human offspring resemble their parents but are not identical to them? Explain.
Answer:
When dealing with two parties theres is going to be a resemblance to both parents slightly favouring ones characteristics more obviously but identical to one or the other would be an impossibility with two diffrent genetic pools mixing.
Human offspring resemble their parents but are not identical to them due to fact that they get half of their DNA and inherited features from each parent and crossing over.
Humans reproduce by the process called sexual reproduction. Sexual reproduction involves the fusion of sperm and egg called fertilization that means they get their genetic material from mother and father equally.
Offsprings are genetically similar to offspring but not identical due to these factors:
Offspring is produced by a combination of two different parent's gametes and each provides their genetic material to zygote.it generates variation in the offspring due to crossing over and fertilizationThese variations give them adaptable offspring as a survival advantage.Thus, the correct answer is - they get half of their DNA and inherited features from each parent and crossing over.
