Answer:
B
Explanation:
Matthias Jacob Schleiden was a German botanist who, with Theodor Schwann, cofounded the cell theory. In 1838 Schleiden defined the cell as the basic unit of plant structure, and a year later Schwann defined the cell as the basic unit of animal structure.

Where does the energy come from that makes the movement of air and water possible?
Answer: Solar energy
Explanation:
The water and wind cycle is driven by the solar energy. The solar energy evaporates the water from the water bodies like oceans, rivers, lakes, and ponds and from other sources of water.
The earth's surface absorbs the heat radiations from the solar energy and the air above the earth's surface get hotter due to absorption of heat.

the ball is pushed so it begins to roll down the hill . it now has _______
A) kinetic energy
B) a rest position
C) more potential
D) no energy
Hi there!
[tex]\large\boxed{\text{A) Kinetic Energy}}[/tex]
When an object begins at rest but a force acts upon it to cause it to be in motion, energy transfer occurs.
In this instance, the ball was initially at rest, so it had potential energy. Once the ball begins is in motion, however, the potential energy is converted into Kinetic Energy.

Purple flowers are dominant over white flowers. A heterozygous purple flower is crossed with another heterozygous purple flower. What will the ratio of purple to white be?
3:1
1:3
2:2
4:0
Answer:
The ratio will be 3:1
Explanation:
edge 2020
The ratio of the purple to white flowers produced from a cross between two heterozygous purple flowers will be 3:1. Thus, the correct option will be A.
What is a Genetic cross?A genetic cross is the deliberate breeding of two different individuals which results in the production of offspring that carry part of the genetic material from each of the two parents. The parent organisms must be genetically compatible to each other and may also be from different varieties or two closely related species.
Genetic cross diagrams are made using Punnett squares that show how likely the offspring are to inherit the characteristics from both of their parents.
In the given condition, two heterozygous purple flower parents are crossed. Here, the purple flower color is dominant over white flower color and from this cross, the organisms produced in 3:1 ratio with three purple flower plants and one white flower plant.
Therefore, the correct option will be A.

What are the parts of the pistil and stamen?
Which part is male and which part is female?
The male parts of the flower are called the stamens and are made up of the anther at the top and the stalk or filament that supports the anther. The female elements are collectively called the pistil. The top of the pistil is called the stigma, which is a sticky surface receptive to pollen.

A red Corvette is traveling down Broad St. At 45mph. The speeld limit is 25 mph. The car is captured on camera speeding, how many miles per hour was the car traveling over the speed limit?
Answer:
The answer is 20 mph
Explanation:
This question is more technical than it is of actual calculation. The car was travelling at a speed of 45 miles per hour when the actual speed limit that should be observed is 25 miles per hour. His excess speed can be calculated as
45 mph - 25 mph = 20 mph
Thus, the car was travelling at a speed of 20 mph more than the actual speed limit of the road which is 25 mph

Name two other subcellular structures that can be found in an animal cell.
1. ......
2. .......
Answer:
Any two other subcellular structures that can be found in an animal cell are:
nucleus.
mitochondria
The two other subcellular structures that can be found in an animal cell are nucleus and mitochondria.
An animal cell is a type of eukaryotic cell which lacks a cell wall and has a true, membrane-bound nucleus along with other cellular organelles which are present.Animal cells range in size from a few microscopic microns to a few millimetres.
Animal cells are eukaryotic cells with a membrane-bound nucleus. Furthermore, these cells exhibit the presence of DNA inside the nucleus. They also comprise other membrane-bound organelles and cellular structures that carry out specific functions necessary for a cell to function properly.
A nucleus is defined as a double-membraned eukaryotic cell organelle that contains the genetic material.It contains the cell’s hereditary information and controls the cell’s growth and reproduction.
The nucleus has been clearly explained as a membrane-bound structure that comprises the genetic material of a cell.
A mitochondrion is an organelle found in the cells of most eukaryotes, such as animals, plants and fungi. Mitochondria have a double membrane structure and use aerobic respiration to generate adenosine triphosphate (ATP), which is used throughout the cell as a source of chemical energy.
Thus, two other subcellular structures that can be found in an animal cell are nucleus and mitochondria.

3 reasons why bringing back extinct animals would help preserve the planet
Answer:
3 reasons why to bring back extinct animals would help preserve the earth is:
1.) Revived species could also assist conservation by acting as a “flagship species”.
2.) People may be excited to see a formerly extinct species, and are more willing to engage in conservation.
3.) At the same time, extinct species could also reinforce the preservation and protection of natural habitats.

Hypothesize what the results would be if a large cell managed to divide, despite the fact that it had grown beyond an optimum size
Answer:
Hypothesize what the result would be if a large cell managed to divide, despite the fact that it had grown beyond an optimum size. The resulting cells could not sustain themselves if the plasma membrane to cell contents (SA to Volume) ratio was too small a difference.
Explanation:
It is likely that the resulting daughter cells would be smaller than normal and may not function properly, potentially leading to impaired growth or viability of the organism.
What happens when cells divide after growing beyond an optimum size?If a large cell managed to divide despite the fact that it had grown beyond an optimum size, it is likely that the resulting daughter cells would be abnormal in size or function. Cells that are larger than the normal range for their type tend to have problems with DNA synthesis and cell division. The DNA may not be accurately replicated, leading to genetic errors and abnormal gene expression. The cell division process may also be impaired, resulting in cells that are larger or smaller than normal.
The consequences of these abnormalities could be serious and potentially harmful to the organism. Abnormal cells may be unable to perform their normal functions, leading to deficiencies or malfunctions in the tissues or organs where they are located. In extreme cases, abnormal cells may become cancerous and contribute to the development of tumors. For these reasons, it is important for cells to divide when they are at an optimal size, in order to ensure that the daughter cells are healthy and functional.

Consider a population of 100 fox squirrels. The population is increasing exponentially, by a rate of 30% each year. If this rate continues, how many fox squirrels will there be in this population after two years?
Answer:
Future population = 169 squirrels
Explanation:
Given:
Current population = 100
Rate of growth = 30 % = 0.30
Time = 2 year
Find:
Future population
Computation:
Future population = 100(1+0.30)²
Future population = 100(1.30)²
Future population = 100(1.30)²
Future population = 169 squirrels
