In an experiment, researchers find that certain neurons in the visual cortex preferentially fire in response to a bar of light that is oriented at a specific angle, and that different neurons similarly respond to bars of light oriented at different angles. This finding provides the strongest evidence for:

Answers

Answer:

Feature detection

Explanation:

Feature detection involves different neurons that are activated in response to specific stimuli. For example, feature detectors are activated in the cerebral cortex through visual stimuli of specific shapes or patterns. These neurons become more and more complex as the stimuli also become progressively more complex and specific. Featured detector neurons have been identified in the toad vision, where they have been involved in the toad's behavior in response to worm-like moving stimuli (e.g., orienting), and the bat auditory cortex, where they have been involved in the measurement of the distance between the bat and its prey.

different between dominant character and recessive character​

Answers

Dominant character:are always expressed when the connected allele is dominant,even if only one copy of the dominant trait exits.

Recessive character:are expressed only if both the connected allele are recessive.

Answer:

Dominant and recessive traits exist when a trait has two different forms at the gene level. The trait that first appears or is visibly expressed in the organism is called the dominant trait. The trait that is present at the gene level but is masked and does not show itself in the organism is called the recessive trait.

Explanation:

If some traits are absent or not expressed, but found in the parent, then the allele is said to be recessive.

"What if speciation occurred in humans?" Your essay should give a clear and precise example of speciation.
A student is asked to write an essay over the hypothetic prompt above. While brainstorming, the student came up with
four different ideas for their essay. Which idea is BEST aligned with the writing prompt and instructions?

Answers

The term speciation refers to the process by which two or more different species are produced from a single original population by different speciation mechanisms. Speciation occurs in three main steps: separation of the original population, divergence (trophic divergence, reproductive divergence, genetic divergence, etcetera), and isolation.

The most related option to speciation is  B. Two populations of humans living on separate sides of the ocean. After a catastrophic event, travel across the ocean is not possible. After millions of years of separation, the two groups are no longer able to produce viable offspring together, but can still produce within their isolated groups.

Speciation occurs when the original population is divided into two groups.  They inhabit different places and are exposed to varying environmental conditions. With time, each group experience many genetic changes. These mutations depend on each group´s environment and its ecological pressures, and they accumulate in time. Pressures act on individuals and make them adapt to the new environmental conditions. Generation after generation, the genotype of individuals will increase the fitness to survive and reproduce. Fixation of mutations will increase the difference between the two groups, up to the diverging point into two new species. Even is they get together again, these species will not be able to mate and produce offspring, and if they do, the new generations will not be viable or fertile.

The exposed case of two human population living on different sides of the ocean, is an example of allopatric speciation.

Allopatric speciation refers to the geographic separation of a continuous genetic background, originating two or more new geographically isolated groups. During these events of speciation, emerging new barriers impede genetic flow between groups, as the two new populations that are separated can not get together and mate anymore. These barriers might be geographical or ecological.  

Different stages are involved in the allopatric speciation process:

• The emergence of the barrier.  

Interruption in the genetic flow

Slow and gradual differentiation due to the occurrence of mutations in each population and their accumulation in time.  

Genetic divergence by natural selection and reproductive isolation,  impeding the two groups to mate even if the barrier disappears.  

Prezigotic isolation mechanisms favored by selection a secondary contact between the new species occurs.

A researcher is studying three wolf packs that hunt in the same area. The first pack preferentially kills mature, healthy moose; the second pack preferentially kills sick, old moose; and the third pack tends to kill an equal number of healthy and sick moose. Which pack likely plays the greatest role in determining the birth rate of the moose population

Answers

Answer:

The correct answer is - the pack that preferentially kills mature, healthy moose.

Explanation:

The birth rate is the number of individuals born in a population in a particular amount of time period. The birth rate can be determined by the individual born in a particular time period and that depends on how many healthy and viable individuals in a population can reproduce and produce new individuals.

Old and sicks are not the ones who can actively participate in reproduction and, however, if the number of healthy and mature individuals are killed there would be fewer newborns in the population.

Thus, the correct answer is the pack that preferentially kills mature, healthy moose.

What does the phosphorylation of Cdc25 by M-Cdk do? Question 4 options: It inactivates Cdc25, which promotes activation of more M-Cdk. It activates Cdc25, allowing the cell to exit mitosis. It activates Cdc25, which inactivates M-Cdk. It inactivates Cdc25, preventing further activation of M-Cdk. It activates Cdc25, which in turn activates more M-Cdk.

Answers

Answer:

It activates Cdc25, which in turn activates more M-Cdk

Explanation:

Cyclin are enzymes that regulate cell cycle progression by the activation of cyclin-dependent kinases (CDKs). These cyclins have no enzymatic activity on their own but they can activate Cdks by binding and phosphorylating them. CDKs can be activated by phosphorylation of activating sites and/or dephosphorylation of inactivation sites. Moreover, M-phase cyclins are cyclins that form M-CDK complexes in order to modulate the cell's entry into mitosis. Cdc25 is a phosphatase involved in the eukaryotic cell cycle which is well-known to regulate the entry into and progression during S (DNA Synthesis) phase and mitosis. In this regard, it has been shown that mitotic phosphorylation of Cdc25 by M-Cdks increases its intrinsic phosphatase activity, thereby Cdc25 is able to remove inhibitory phosphates from M-Cdk and, consequently, activate more M-Cdks.

A mutation occurred in the following DNA sequence AGCCTAGCC and the mutated form is now AGCCTTAGCC. Which of the following correctly describes the result of this mutation?

1.A deletion occurred so all of the amino acids added after the mutation may be wrong.

2.An insertion occurred so all of the amino acids added after the mutation may be wrong.

3.A substitution occurred so all of the amino acids added after the mutation will definitely be wrong.

4.An insertion occurred so all of the amino acids added after the mutation definitely will be different.

Answers

Answer:

Explanation:

1.A deletion mutation occurs when a wrinkle forms on the DNA template strand and subsequently causes a nucleotide to be omitted from the replicated strand.

2.This type of variant results in a shortened protein that may function improperly, be nonfunctional, or get broken down. An insertion changes the DNA sequence by adding one or more nucleotides to the gene.

3. A substitution mutation can cause the following: Change in the coding of amino acids codon to a particular stop codon resulting in an incomplete protein, which is usually non-functional. Can cause Silent mutations where a codon change can encode the same amino acid resulting in no changes in the protein synthesized.

4. when a premature nonsense or stop codon is introduced in the DNA sequence. When the mutated sequence is translated into a protein, the resulting protein is incomplete and shorter than normal. Consequently, most nonsense mutations result in nonfunctional proteins.

What is the difference between a food chain and food web

Answers

A food chain follows one path of energy and materials between species. A food web is more complex and is a whole system of connected food chains. In a food web, organisms are placed into different trophic levels. ... Producers are the basic trophic level while top predators are the peak level.

Answer:

A food chain is a sequence of organisms through which nutrients and energy pass as one organism eats another. A food chain must start with energy from the sun, have a producer (an organism that makes food by itself with energy from sun), and have at least one consumer eat and gain nutrients from another consumer or a producer. At the end of the food chain, there must be a decomposer to break down the dead animals into nutrients, which is beneficial for soil. Additionally, there must be arrows to indicate the flow of energy travelling from one organism to another. An example of a food chain would be:

sun -> roses -> caterpillar -> crows -> garter snakes -> mushrooms

Energy source: Sun

Producer: Roses

Consumer: Caterpillar

Secondary consumer: Crows

Tertiary consumer: Garter snakes

Decomposer: Mushrooms

A food web is basically an interconnection of multiple food-chains in a graphical representation to see which animal eats what and their niche (role they play in an ecological community). Here's an example of a food web (not mine, credits to creator):

Why do cells use fat and starch for long-term energy storage instead of ATP molecules?
O ATP is used for long-term storage, while fat and starch are used for immediate energy.
O ATP is used for short-term energy and to build molecules of starch and fat.
O Fat and starch are unstable and can be stored short-term, while ATP molecules are stable and stored long-term.
O Fat and starch are stable if used as energy immediately, while ATP is used as long-term storage.

Answers

The answer to your question is B :)

Answer:

Cells use fat and starch for long-term energy storage instead of ATP molecules because fat and starch are more efficient energy storage molecules than ATP.ATP is a molecule used for immediate energy, not for long-term energy storage.

Fat and starch are complex carbohydrates that can be broken down to release energy. Fat molecules are primarily composed of carbon and hydrogen, while starch is made of glucose molecules.Both fat and starch can be broken down through cellular respiration to produce ATP molecules that can be used to power various cellular processes.
However, because fat and starch molecules contain more chemical energy than ATP, they can provide a much larger amount of energy over a longer period of time.

Furthermore, ATP molecules are relatively unstable and cannot be stored for long periods of time, while fat and starch can be stored in specialized cellular structures for long-term energy needs.
