Accelerating it.
Explanation:
Dark energy is a hypothesis by which the growing tendency of the universe to expand constantly is explained, with which it is inferred that this dark energy is a kind of inverse gravity, which instead of attracting repels the extremes of the cosmos expanding its size and dimension . Although its definition is very ambiguous and abstract, the truth is that it is a hypothesis that seeks to explain this physical behavior of the cosmos.

During DNA replication, the DNA polymerase enzyme produces a complemetary strand from each of the original strands.
What is DNA replication?It is the process by which DNA produces a copy of itself at the time of cell division. In the process of replication, the initial step is the unzipping of the double helix structure of the DNA. This is done with the help of enzyme helicase. The unzipping creates a Y shape composition called replication fork.
Towards the replication fork, one of the strands is oriented in the 3' to 5' direction, known as the leading strand. The other strand in the 5' to 3' direction is the lagging strand, which is away from the replication fork.
The primer combines with the leading strand, and marks the intiation point of the synthesis of DNA. After this, DNA polymerase combines with the leading strand and add complementary nucleotide bases in the 5' to 3' direction.
In the lagging strand, numerous primers come and bind, later the chunks of DNA called Okazaki fragments are supplemented to the lagging strand in the 5' to 3' direction, by the enzyme DNA polymerase. This kind of replication is termed discontinuous as the Okazaki fragments are joined up later.
Thus, the correct statement is the second one, that is, the DNA polymerase enzyme produces a complemetary strand from each of the original strands.

How do the daughter cells at the end of mitosis and cytokinesis compare with their parent cell when it was in interphase of the cell cycle?
Answer:
The daughter cells have the same number of chromosomes and the same amount of DNA.
Explanation:
Mitosis is a process where the nucleus divides, so at first we have 46, and we need to bring it down to 23, because that is how much our cells can take, but after mitosis, the daughter cell will end up with 2 new cells, and it will have 23 chromosomes in each of the cells.

How dose the process of photosynthesis create food
Answer:
Plants, like all living things, need food to survive. Plants make their food using a process called photosynthesis, which means “putting together through light.” During photosynthesis, a plant traps energy from sunlight with its leaves. It also takes up water from its roots and carbon dioxide gas from the air.

Answer:
[tex]f=5.6\times 10^{14}\ Hz[/tex]
Explanation:
The resulting light have a wavelength of 532 nm.
We need to find frequency of the material. Let it is f.
The relation between frequency and the wavelength is given by :
[tex]c=f\lambda\\\\f=\dfrac{c}{\lambda}\\\\f=\dfrac{3\times 10^8}{532\times 10^{-9}}\\\\=5.6\times 10^{14}\ Hz[/tex]
So, the frequency of the light is [tex]5.6\times 10^{14}\ Hz[/tex]. Hence, this answer is correct.

If the desert experiences a prolonged drought where many of the plants die, which BEST predicts the effect on the carrying capacity of the ecosystem?
A
The carrying capacity of the ecosystem will increase because there will be more space available for organisms.
B
The carrying capacity of the ecosystem will increase because there will be fewer organisms that require resources.
C
The carrying capacity of the ecosystem will decrease because there will be less food available for many organisms.
D
The carrying capacity of the ecosystem will decrease because there will be fewer organisms competing for resources.
Answer:
c
Explanation:
there will be way less vegetation to attract pet and many organisms will die because of the lack of resources due to the drought
If the desert experiences a prolonged drought where many of the plants die, the carrying capacity of the ecosystem will decrease because there will be less food available for many organisms.
What is ecosystem?"An ecosystem consists of all the organisms and the physical environment with which they interact."What do you man by carrying capacity?"The carrying capacity is the maximum population size of a biological species that can be sustained by that specific environment, given the food, habitat, water, and other resources available."Due to draught, resources decreases (resources becomes limited) and many organisms would die because of starvation. This would also effect in the food chain of other organisms. The organism would now compete for the lesser amount of resource.
Hence, the correct option is C. The carrying capacity of the ecosystem will decrease because there will be less food available for many organisms.

PLEASE HURRY,(GIVING BRAINLIEST) (THE ACTUAL SUBJECT IS SCIENCE)After a major forest fire kills all of the plants in an area, the first plants to grow in the burned area are often types of grass. Because they are the first thing to grow in the new ecosystem, these types of grass are called pioneer species. What adaptations would help the grass be a successful pioneer species?
A.
slow reproduction and the ability to grow in sunny places
B.
rapid reproduction and the ability to grow in sunny places
C.
slow reproduction and the ability to grow in shady places
D.
rapid reproduction and the ability to grow in shady places
Answer: B
Explanation:
To help the pioneer species to grow, it needs to have rapid reproduction. But, it also needs the sun to grow very well. If it does not have the Sun, it will most certainly die and be endangered in the area. The answer is B, we need both rapid reproduction and the Sun.
Answer:
rapid reproduction and the ability to grow in sunny places
Explanation:
After a major fire, less sunlight is blocked by trees and other plants. Plants that can use the increased sunlight are more likely to thrive in the new environment. Rapid reproduction would help a plant species to spread more quickly to take advantage of the resources and lack of competition. Therefore, the adaptations that would help grass be a successful pioneer species are rapid reproduction and the ability to grow in sunny places.

Suppose you are studying a population of bark beetles who experience a pattern of exponential growth followed by population crashthat tends to repeat with time. You also observe that this population appears to be density independent, so that they are not really affected by competition. What might you say about their life history?
Answer:
The following can be deduced from the life history of bark beetles;
* All bark beetles life stages are spent in the phloem, internal bark, and bark, aside from when grown-ups leave the tree they created in to travel to new host trees. Bark beetles feed on the phloem of their host trees during grown-up and larval stages.
* Many bark beetles travel toward debilitated host trees, be that as it may, during environmental conditions ideal for population improvement, populaces may develop quickly and effectively assault healthy trees.
Explanation:
Bark beetles determine their name since they live and create in the bark and wood of trees and bushes. Grown-ups unearth egg displays in living bark (phloem).
Bark beetles are the most dangerous creepy insects in western coniferous woodlands. It has been assessed that 90% of insects caused tree mortality and over 60% of the complete insect caused loss of wood development in the US is because of bark beetles.

The relationship between kinetic energy and speed is ____ proportional.
Answer:
Directly
Explanation:
hope this helps
The relationship between kinetic energy and speed is directly proportional.
What is kinetic energy?The energy an object has as a result of motion is known as kinetic energy. A force must be applied to an object in order to accelerate it. We must put in effort in order to apply a force.
After the work is finished, energy is transferred to the item, which then moves at a new, constant speed.
The human body produces kinetic energy while it is in motion. For instance, when a person runs, their legs and feet build up kinetic energy, which is typically turned to heat.
An object's kinetic energy is directly inversely related to its square of speed. So, the kinetic energy will multiply by four for every twofold rise in speed.
Thus, it can be concluded that kinetic energy is directly proportional to speed.

In fruit flies, curved wings are recessive to straight wings, and ebony body is recessive to gray body. A cross was made between flies (all true-breeding) with curved wings and gray bodies to flies with straight wings and ebony bodies. The F1 offspring were then testcrossed to produce an F2 generation. The following data were obtained: F2 generation: -104 curved wings, ebony body -106 curved wings, gray body -98 straight wings, gray body -92 straight wings, ebony body With a null hypothesis based on independent assortment, what are the expected values for each class of flies (400 total flies)
To know if two genes are linked or assort independently, a testcross can be performed. If the progeny distribution differes from the expected ratio, they are linked. Extected numbers: -100 curved wings, ebony body -100 curved wings, gray body -100 straight wings, gray body -100 straight wings, ebony body.
How are independent and linked genes transmitted?
Independent assortment law establishes that the alleles from two or more different genes distribute independently from each other in gametes.
Each gamete receives an allele from a gene that does not depend on nor influence another gene's allele in the same gamete. This event only occurs in independent genes. These genes segregate independently after crossing over because they are far away from each other.
Some other genes, however, are too close to each other, and they do not segregate independently. These are the linked genes. They do not exhibit an independent distribution, and they are inherited together more frequently.
To know if two genes are linked, we must observe the progeny distribution.
If heterozygous individuals, whos genes assort independently, are test crossed, they produce a progeny with equal phenotypic frequencies 1:1:1:1. If we observe a different distribution, that is that phenotypes appear in different proportions, we can assume that genes are linked in the double heterozygote parent.In the exposed example,
curved wings (s) are recessive to straight wings (S), ebony body (g) is recessive to gray body (G).1st Cross: flies with curved wings and gray bodies to flies with straight wings and ebony bodies.
