How do most bacteria get food?
Answer:
Foodborne illness/contamination
Explanation:
Most dairy and meat products are at risk for having salmonella, this is why you must cook
it so you can kill the bacteria. These foods can contaminate fresh veggies that you don't cook which can cause you to get sick.
When the water availability of a plant's environment decreases, the plant can respond by closing its stomata. This reduces the amount of water that the plant loses through its leaves due to transpiration. Closing the stomata also reduces the amount of carbon dioxide that the plant can take in through its leaves, which will most likely result in A. a decreased rate of photosynthesis. B. no change in the cellular processes of the plant. C. an increased rate of photosynthesis. D. an increased rate of cellular respiration.
Answer:
A. a decreased rate of photosynthesis.
Explanation:
Stomata is a structure in the leaves of higher plants, which they use majorly for the purpose of gas exchange. However, the process whereby plant loses water called transpiration also occurs via the stomata. In a situation whereby the availability of water in a plant's environment is low, the plant responds by closing its stomata in order to conserve water (reduce the amount of water that the plant loses through its leaves due to transpiration).
Closing the stomata by plants means not allowing ample carbon dioxide (CO2), which is needed for the process of photosynthesis to occur, to enter the plant. This will most likely result in a DECREASED RATE OF PHOTOSYNTHESIS.
is an organism that uses the energy from the sun or inorganic substances to make its own food; it is also called a producer. is an organism that takes in or consumes other organisms to receive energy; it is also called a consumer.
Answer:
An autotroph
is an organism that uses the energy from the sun or inorganic substances to make its own food; it is also called a producer.
A heterotroph
is an organism that takes in or consumes other organisms to receive energy; it is also called a consumer.
Explanation:
An autotroph is an organism that uses the energy from the sun or inorganic substances to make its own food; it is also called a producer. A heterotroph is an organism that takes in or consumes other organisms to receive energy; it is also called a consumer.
What are autotrophs and heterotrophs?An autotroph can be referred to as an organism which uses the energy from the Sun or inorganic substances present in the environment to make its own food. These organisms are also called as producers. These organisms produce their own food through the process of photosynthesis.
Heterotrophs are the organisms which takes in or which consumes other organisms for receiving energy or as the food source. These organisms are also called as consumers. Consumers are further divided into different types on the basis of their food such as carnivores, omnivores, etc.

Muscles have a bunch of nuclei because they need to use the DNA in the nuclei to make the large number of proteins that they must contain, so that they can relax and contract. What other organelle might muscles need a larger than normal number of?
Centrioles, so that muscle cells can retain a rigid structure during times of heavy stress (for example: lifting a heavy weight).
Mitochondria, so that muscle cells can quickly respond to the need to relax and contract.
Vesicles, so that muscle cells can ensure water availability if there is unusually low availability of water.
Answer:
it's the Mitochondria
Explanation:
The other organelle that might muscle needs a larger than normal number of is mitochondria, so that muscle cells can quickly respond to the need to relax and contract. The correct option is b.
What are mitochondria?Mitochondria is a cell organelle that is present in both plant and animal cells. It is not present in prokaryotic cells, as prokaryotic cells do not contain cell organelles. Besides storing ATP, it also generates energy that is generated from glucose.
Muscle cells have mitochondria to accommodate this energy demand. These organelles, often known as the “power plants” of the cell, transform nutrients into the molecule ATP, which serves as a form of energy storage.
Therefore, the correct option is b. Mitochondria, so that muscle cells can quickly respond to the need to relax and contract.

Gestational diabetes occurs when a pregnant woman has high levels of blood sugar. Cells in the pancreas usually keep blood sugar levels normal, but hormones produced during pregnancy deactivate the cells. After pregnancy, hormone levels return to normal, and so do the pancreas cells. Is this an example of DNA or the environment controlling gene expression? Explain your answer
Answer:
environment controlling gene expression
Explanation:
Gestational diabetes generally occurs in pregnant women. The sugar level in the bloodstream becomes little high than the normal range during pregnancy. But the glucose level returns to normal after child birth.
The pancreas secrets insulin which helps to lower the blood sugar level in the body. But during pregnancy, the placenta releases some of the hormones which dilutes the effect of insulin. This is known as insulin resistance. So now the pancreas secretes more of insulin to overcome this insulin resistance for the body. Now if a woman during pregnancy does secrete more insulin, the glucose level increases in the body and the woman develops gestational diabetes.
Gestational diabetes greatly depends upon obesity and the ethnicity of the women, but a definite genetic link has not been identified.
This it is a result of the environment control gene expression.

An apple farmer notices that two of his trees produce particularly sweet apples. The farmer thinks that these sweeter apples would sell very well andcould make him a lot of money. He uses a Q-tip to pollinate the flowers of the sweet apple tree with pollen from the other sweet apple tree's flowers. He then takes the seeds from the fruit that they produce and grows a new field of trees from them. Almost all of these new trees make very sweet apples like the first two trees did.
Answer:
It is a right method for making a variety.
Explanation:
This is the right method for making sweet apples variety because in apple, cross pollination occurs and for making a new variety self pollination is the best way to prevent impurities in making a new variety. Due to self pollination, the farmer gain the sweet apple variety which help them to make more money by selling these sweet apple because of its demand.
In Units 4A and 4B, we have learned about photosynthesis and cellular respiration. Which of the following statements is true?
a. The reactants of photosynthesis are the reactants of cellular respiration.
b. Photosynthesis produces light energy while cellular respiration produces chemical energy.
c. The products of photosynthesis are the reactants of cellular respiration.
d. Photosynthesis and cellular respiration use light energy to convert to chemical energy.
Answer:
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

Given the diagram below, which of the following ordered pairs represents the
vertex, A?
O A. (b cosc, b sinC)
O B. (b cos C, c sinc)
O C. (a cosB, a sinB)
O D. (a cosc, b sinC)
Answer:c
Explanation:because cosin of b is c
(a cosc, b sinC) pairs represents the vertex A in this diagram. Hence option D is correct.
What is Vertex ?In geometry, a vertex (in plural form: vertices or vertexes) is a point where two or more curves, lines, or edges meet. As a consequence of this definition, the point where two lines meet to form an angle and the corners of polygons and polyhedral are vertices.
The vertex of an angle is the point where two rays begin or meet, where two line segments join or meet, where two lines intersect (cross), or any appropriate combination of rays, segments, and lines that result in two straight sides meeting at one place.
In a polygon, a vertex is called "convex" if the internal angle of the polygon is less than π radians otherwise, it is called concave.
Hence option D is correct.
