Answer:
During a supernova, the star releases very large amounts of energy as well as neutrons, which allows elements heavier than iron, such as uranium and gold, to be produced. In the supernova explosion, all of these elements are expelled out into space.

Answer:
Definitely A, most likely D as well since B and C dont make too much since in terms of sexual vs. asexual!
Answer:
d.
Explanation:
i’m learning this in my biology class (we’re week 12 i already learned this)
Why cant most stars can make elements like gold and iron
When a star is fusing iron in its core, it's still giving off insane amounts of energy. ... Iron cannot be fused into anything heavier because of the insane amounts of energy and force required to fuse iron atoms. The atomic structure of iron is very stable, more so than most other elements.
Answer:

Which statement best describes trait distribution?
Distribution describes how individuals in a population are spread across their habitat.
Distribution describes how the variation in traits is spread across a population.
Distribution describes the different traits that are found in a species.
Distribution describes the different traits that are found in a population
I will post answer in comments
The statement 'distribution describes the different traits that are found in a population' BEST describes trait distribution. It involves the variation of a phenotypic trait.
Trait distribution refers to the differences among populations in the frequency distributions of the states for a specific phenotypic trait.
Variation of a phenotypic trait in a population is the result of genetic factors and environmental factors and the interaction of these factors.
Heritability of a trait refers to the percentage of variation in a trait that is due to genetic factors.

______ is the conversion of one form of energy to another. In biology, it is used to describe the conversion of stimulus energy into an electrical signal in the nervous system.
In Biology, the conversion of an energy form into another form of energy such as the conversion of stimulus energy into an electrical signal in the nervous system of a living organism is referred to as: Transduction.
Energy can be defined as the ability (capacity) of a living organism to do work and it is measured in calories or Joules (J).
Transduction refers to a process through which the signal message contained in the outside of a living cell is converted into a message within or inside the living cell.
On a related note, transduction can be used to describe the conversion of an energy form into another form of energy.
In Biology for instance, the conversion of stimulus energy into an electrical signal in the nervous system of a living organism can be described by using transduction.

A single base substitution mutation is least likely to be deleterious when the base change results in _____.
A single base substitution mutation is least likely to be deleterious when the base change results in a codon that specifies the same amino acid as the original codon.
What is the effect of single base substitution mutation?
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.
What is base substitution mutation?Base substitutions are the simplest type of gene-level mutation, and they involve the swapping of one nucleotide for another during DNA replication. For example, during replication, a thymine nucleotide might be inserted in the place of a guanine nucleotide.

Answer:
The soft palet and uvula
Explanation:
As climate changes because of global warming, plant species' ranges in the northern hemisphere may move northward. The trees that are most likely to avoid extinction in such an environment are those that ________. A. have larger, more contiguous established populations to begin with B. produce well-provisioned seeds C. have seeds that become viable only after a forest fire D. disperse many seeds in close proximity to the parent tree
The trees that are most likely to avoid extinction in such an environment
have seeds that are easily dispersed by wind or animals .
Trees which are easily dispersed by wind or animals have a very high chance of survival because the seeds dispersed will grow to form trees and if there is death of some they will still be present due to the continuous seed dispersal.
This is the main reason why the seeds with more dispersal means will not
become extinct.

Which type of cell is being described in the following passage? The cell has a large surface area due to its biconcave shape. It is able to store lots of haemoglobin as it does not have a nucleus.
Answer:
Red blood cell
Explanation:
Red blood cell has a large surface area due to its biconcave shape. It is able to store lots of haemoglobin as it does not have a nucleus.
Red blood cells have the form of a flat disk, resembling a doughnut, that is spherical, has an indentation in the middle, but is not hollow.
What are the different characteristics of Red blood cell?Red blood cells are minuscule. Unlike white blood cells, red blood cells don't have a nucleus, which makes it easier for them to alter shape and circulate around your body.
Red blood cells are disc-shaped, biconcave structures without a nucleus or organelles. Red blood cells' adaptation to transfer gases is visible in their form.
The surface area through which Hades can diffuse is expanded. Additionally, the cell's structure brings oxygen-carrying hemoglobin molecules closer to it.
Therefore, Red blood cell has a large surface area due to its biconcave shape. It is able to store lots of hemoglobin, as it does not have a nucleus.

In Mendel's experiments, if the gene for tall (T1) plants was incompletely dominant over the gene for short (T2) plants, what would be the result of crossing two T1T2 plants
Answer:
25% would be tall (T1T1), 50% would be intermediate height (T1T2), and 25% would be short (T2T2)
Explanation:
25% would be tall (T1T1), 50% would be of average height (T1T2), and 25% would be under five feet (T2T2).
What is incomplete dominance?When a dominant allele, or form of a gene, does not entirely block the effects of a recessive allele, the resultant physical appearance of the organism reveals a mixing of both alleles. It is sometimes referred to as partial or semi-dominance.
There are two different forms of genetic inheritance, full dominance, and codominance. Codominance basically implies that neither allele is able to suppress or obstruct the expression of the other allele.
The cross between T1T2 X T1T2 is attached in the image below.
However, incomplete dominance occurs when a dominant allele only partially obscures the effects of a recessive gene.
