a
cell growth
b
DNA synthesis
c
the organelles are copied
d
the nucleus divides
Answer:
I am pretty sure that the answer is D
Explanation:
The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells.

1. A rabbit can cover a distance of 80 min 5 s. What is the speed of the rabbit?
Answer:
[tex]\boxed {\tt 16 \ m/s}[/tex]
Explanation:
Speed can be found by dividing distance by time.
[tex]s=\frac{d}{t}[/tex]
The rabbit travels 80 meters in 5 seconds.
The distance is 80 meters and the time is 5 seconds.
[tex]d= 80 \ m \\t- 5 \ s[/tex]
Substitute the values into the formula.
[tex]s=\frac{80 \ m }{5 \ s}[/tex]
Divide.
[tex]s= 16 \ m/s[/tex]
The rabbit's speed is 16 meters per second.
How far does an animal have to travel to obtain the abiotic factor water?
Answer:
Three fourth of the total earth is covered with water, 97 percent of which is there in sea's as saline water, the other 2 percent is there in the form of glaciers and the left out 1 percent is there as ground water.
Water is presence is abundance but it depends upon the geographical location where the animal is looking for water. There will be scarcity of water in the deserts because there is less rainfall over there, so it depends on the geographical location.

Which of the following hazards can severely harm a worker's lungs?
heat exposure
vehicle hazards
bins and silos
excessive noise
Which of the following hazards can severely harm a worker's lungs?
A). Heat Exposure.
Explanation:
In terms of weather/overall Heat: Inhaling hot air, induces airway constriction making it difficult to breathe. This can be especially so with people with lung conditions. It's also found that this can cause COPD and many respiratory air conditions.
In terms of fire: Of course, it's known that smoke from fire can have a terrible effect on your lungs. It can restrict oxygen flow, which can and most likely be deadly.
Why it's not the other options:
b). Vehicle Hazards: This one would most likely have no or little correlation with lung health. Also, it's not specific enough.
C). Bins and silos don't have as much effect on the lungs as Heat exposure does.
D). Excessive noise would effect mainly the ears, not lungs.

Two organisms mate and produce infertile offspring. Which is a true statement about why it is not able to reproduce?
A. The parents are a different genus and species
B. The parents are a different species, but the same genus
Answer:
a
Explanation:
a is the correct answer
The statement which is true about why it is not able to reproduce is that the parents are a different genus and species. Thus, the correct option for this question is A.
What is Species?Species may be defined as the collection of organisms that can significantly reproduce with one another in nature and produce fertile offspring.
According to the context of this question, the process of speciation takes place when the members of similar populations no longer interbreed with one another in order to produce fertile offspring within their natural environment. So, the mating of two organisms can not produce fertile offspring until they belong to the same genus and species.
Therefore, the statement which is true about why it is not able to reproduce is that the parents are a different genus and species. Thus, the correct option for this question is A.

Answer:
Substitution Mutations
Explanation: A substitution mutation occurs when specific bases (A, T, C or G) in a gene are swapped for different ones. This type of mutation doesn't cause a difference in the number of bases like insertion or deletion mutations do. Substitution mutations just switch out one or more bases for different ones.

A substitution mutation occurs when a base in the DNA sequence is replaced by a different base.
What do you mean by substitution mutations?Substitution is a type of mutation in which one nucleotide is replaced by a different nucleotide. The term can also refer to the replacement of one amino acid in a protein with a different amino acid.
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 place of a guanine nucleotide.
Substitution mutations can be good, bad, or have no effect. They cause three specific types of point mutation: silent, missense, and nonsense mutations.

Which step is the beginning of photosynthesis?
Answer:
light dependant reactions
Explanation:
Photosynthesis is carried out by green plants. The initial step of photosynthesis is the photolysis of water. This is a part of the light reaction.
What is photosynthesis?Photosynthesis is completed in two steps: the light-dependent reaction and the light-independent reaction. The sun is required for the light-dependent reaction. Two photosystems are involved in the light reaction. Light reaction starts from photolysis of water.
The reaction starts at photosystem II (PSII). At this site, the photolysis of water takes place. As a result, sunlight causes the water to break and electrons to be released. This electron moves to plastoquinone. During the electron movement, protons are pumped to the thylakoid lumen.
From the plastoquinone, an electron moves to the cytochrome complex and then to the PSI complex through plastocyanin. From the PSI complex, the electron moves to NADP reductase to form NADPH. All the protons present in the lumen move through the ATP synthase complex, and ATP is produced. The journey of electrons starts with the photolysis of water.
Hence, photosynthesis starts with the breakdown of water molecules.

Explanation:hope this helps
In all organisms, the cell is the fundamental unit of life. Plants, like animals and humans, are made up of multiple cells. The cell wall of the plant cell gives the cell its shape and covers the cell. Other organelles, in addition to the cell wall, are associated with various cellular activities.
What organelles are present in cell ?
Plant cells are eukaryotic cells that differ from other eukaryotic organisms in several fundamental ways. There is a nucleus and similar organelles in animal and plant cells. The absence of a cell wall outside of the cell membrane is one of the plant cell's distinguishing characteristics.The building blocks of plants are called plant cells. The primary function that plant cells perform is photosynthesis.The chloroplasts of a plant cell are where photosynthesis takes place. It is the way that plants use sunlight, carbon dioxide, and water to prepare food. During the process, ATP is produced as energy.Water and nutrients are transported from the roots and leaves to various parts of the plant by a few plant cells.A mature, higher plant's cells become specialized to carry out particular vital functions that are necessary for their survival. Some plant cells are responsible for storing food, while others transport water and nutrients.Parenchyma cells, sclerenchyma cells, collenchyma cells, xylem cells, and phloem cells are the specialized plant cells.To know more about cell check this:

Explanation: What I still wonder about the Mesosarurus that once lived together are found on different locations of the world. One question is what if the animals did swim across the mid ocean ridge? Another question I have is why would the plate boundaries separate for example what caused the divergent plate to suddenly start moving. My last question is why would the plate boundary not suddenly move apart but move gradually over time apart from one another.
The fossils of Mesosaurus that once lived together are found in different locations on Earth now due to a variety of reasons like a mid-ocean ridge, movement of plate boundaries, and continental drift.
What do you mean by Fossils?Fossils may be defined as the dead and organic remains of past living organisms including plants and animals that were buried and preserved deep in the soil millions of years ago.
According to the context of this question, the fossils that once lived together are found in different locations on Earth now itself due to numerous reasons which are described above. These reasons are responsible for some fragmentation of the earth's surface and these fossils were shifted to the part where they are hard or impossible to find.

A student used a microscope to observe Elodea submerged in a solution. The student observed the cell cytoplasm pull away from the cell wall and clump together in the center of the cell. Which statement best explains why this occurred? A-The cell was submerged in a hypertonic solution. B-The cell was submerged in a hypotonic solution. C-The cell was submerged in a pure solution. D-The cell was submerged in an isotonic solution.
Answer:
A
Explanation:
The correct answer would be that the cell was submerged in a hypertonic solution.
A hypertonic solution is a solution with a higher concentration of solutes than that of the cytosol of a cell suspended in it. When a cell is suspended in a hypertonic solution, water moves osmotically from the cytosol to the hypertonic solution. This causes the cytoplasm to collapse and the cell becomes flaccid.
The correct option is A.
Answer:
D. The cell was submerged in a hypertonic solution.
