Desert plants and animals are adapted to the lack of what and high

Answers

The two main adaptations that desert animals must make are how to deal with lack of water and how to deal with extremes in temperature. Many desert animals avoid the heat of the desert by simply staying out of it as much as possible

Answer:

lack of water and high concentration of heat and dryness

Explanation:

Deserts don't get that much rainfall, so desert wildlife are adapted to survive in such a dry climate. Take the camel, for instance, it can store three bathtubs of water in it's hump, so it can go a very long time without water. And without that rainfall, the desert is dry and, usually, very hot. Animals have adapted to this by only coming out in the nighttime when it's cooler.

the independent is the age of the tree and the dependent is the diameter

Explanation:

the diamter of the tree is based off of the age as we can see that it gets bigger the older the tree is

Answer: Independent variable: age of the tree (years), Dependent variable: tree diameter (mm)

The diameter of the tree is dependent on what age the tree is. As the tree gets older, the diameter increases. The dependent variable depends/relies on the value(s) of the independent variable.

Explanation:

A botanist finds that when compared to pink flowers, the population of purple flowers is very high. Ten years later, the population of purple flowers is nearly gone, and the number of pink flowers has tripled. Why would this be?

Answers

Answer:

Because of the reduction or near extinction of the purple flowers noticed by the botanist Ten years after it was in abundance, this fall in the population could be caused by the unfavorable change in the plant's environment. While the pink flowers tripled because some factors in the environment were favorable for its growth.

Explanation:

From the question, it was mention that the botanist noticed at first purple flowers had more population than the pink flowers and that changed after 10 years when the population of the pink flowers tripled and purple flowers were nearly gone. Some of the causes that could be responsible are:

1. Disease and pest attack on the purple flowers.

2. The pink flowers developed a good survival mechanism even in adverse conditions.

3. Environmental stress could also come into play on the purple flowers.

4. Climate which initially supported the growth of the purple flowers had changed. Because variations exist in plants and the ideal conditions necessary for plant growths and proliferation varies among plants.

How does the double helix structure of DNA support its role in encoding the genome?
1)The sugar-phosphate backbone provides a template for DNA replication
2)tRNA pairing with the template strand creates proteins encoded by the genome
3)Complementary base-pairing creates a very stable structure
4)Complimentary base pairing allows for easy editing of both strands of DNA

Answers

Answer: Complementary base- pairing creates a very stable structure

Explanation:

The double helix structure of deoxyribonucleic acid (DNA) support its role in encoding a genome because the: 3. Complementary base-pairing creates a very stable structure.

A double helix can be defined as the spiral configuration of the deoxyribonucleic acid (DNA) molecule.

In Biology, a double helix is typically used to describe the molecular structure of a double-stranded deoxyribonucleic acid (DNA) molecule, which comprises two (2) linear strands that are complimentary and run opposite to each other and twist together (anti-parallel).

Hence, the complementary base-pairing in a double-stranded deoxyribonucleic acid (DNA) or double helix structure of deoxyribonucleic acid (DNA) helps to create a very stable structure, which in turn makes it possible to encode a genome.

In organisms other than plants, when and where is the most ATP produced?
in cytoplasm, during photosynthesis
in nuclei, during cellular respiration
in chloroplasts, during photosynthesis
in mitochondria, during cellular respiration

Answers

Answer:

D. In mitochondria, during cellular respiration.

Explanation:

A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature. A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.

All living organisms such as plants and animals require energy to function properly (life activities). Thus, the organelle where energy from nutrients is released is generally referred to as mitochondria. Animals retrieve energy using mitochondria to do cellular respiration because they typically act like a digestive system by taking in nutrients, breaking them down and obtaining energy rich molecules for cell-life activities.

Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). Therefore, the intermediary products are produced at the glycolysis and citric acid cycle stage.

Basically, mitochondria is one of the cell organelles found in all living organisms and it is known as the powerhouse. Therefore, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.

In organisms other than plants, the most ATP is produced in mitochondria, during cellular respiration.
