1. Luca made the following chart for Earth's four basic movements, what needs to be correct on his chart?

Rotation Speed Revolution Speed Solar System Speed Milky Way Speed
0.3 miles/sec
18.5 miles/sec
370 miles/sec
150 miles/sec

The rotation speed and revolution speed should be switched

The revolution speed and solar system speed should be switched

The rotation speed and Milky Way speed should be switched.

The solar system speed and Milky Way speed should be switched.

Answers

Answer:

The solar system speed and Milky Way speed should be switched.

Explanation:

The speed of the Earth is with respect to how it moves around it's own axis (rotation speed), the Sun (revolution speed), solar system (solar system speed), and the milky way galaxies (milky way speed) etc.

According to this question, Luca made a chart for this Earth's four basic movements. The chart with their respective speed are as follows:

Rotation Speed - 0.3 miles/sec

Revolution Speed - 18.5 miles/sec

Solar System Speed - 370 miles/sec

Milky Way Speed - 150 miles/sec

Luca, however, made a mistake in his chart.

- The rotation speed of the Earth around its axis is correctly 0.3miles/sec

- The revolution speed of the Earth around the sun is correctly 18.5 miles/sec

- The solar system speed of the Earth i.e. around the solar system is about 150miles/hour

- The milky way speed of the Earth i.e. around local group of galaxies is about 370miles/hour.

Based on the comparison of Luca's chart and correct speed illustration, THE SOLAR SYSTEM SPEED AND MILKY WAY SPEED SHOULD BE SWITCHED.

#: Why do you think egg cells are large and sperm cells are small?
HELP!!! ASAP

Answers

Answer:

Because eggs contain amost all organelles, and materials for growth. A sperm only contains haploid chromosome and certian mitochondria for movement.

Explanation:

:)

The egg, like a sperm cell, has a nucleus with half the number of chromosomes as other body cells. Apart from a sperm cell, the egg contains a large amount of cytoplasm, or cell contents, which is why it is so large.

What are gametes?

A gamete is an animal or plant reproductive cell. Female gametes are known as ova or egg cells in animals, while male gametes are known as sperm.

Ova and sperm are haploid cells, with only one copy of each chromosome in each cell. A sperm and an ovum combine during fertilization to form a new diploid organism.

Because the formation of the egg begins before birth inside the developing body of a female embryo and is not completed until the egg is fertilized by a sperm many years later, the egg cell is much larger than the sperm cell.

The sperm cell is small in size because its primary function is to swim to the egg cell.

Thus, the egg cells are large and sperm cells are small.

a cell was poisoned by a substance that destroyed all of its mitochondria. which cell transport processes would be able to still continue?​

Answers

Answer:

Nothing

Explanation:

If a cell's mitochondria were destroyed it would die. Mitochondria are the power houses of the cell and without energy, necessary reactions could not take place .

If a mitochondria stopped working the cell would not have its respiratory function such as to use carbon dioxide, water, and energy in which the cell needs to survive so the cell would eventually stop moving and slowly die out with no nutrients and energy.

Explanation:

the heart pumps blood through your system, keeping you alive. the brain only helps you think. and plus, so many people in this world are dumb so they already surviving without a brain so the obvious answer is heart

I would like to say the heart is more important than our brain but without our brain how do we function. We simply wouldn’t function our brain tells our heart to pump sends impulses throughout our body allowing us to move our bodies speak and talk it converts our vision so we see correctly. The brain just simply does too much to be more important than the heart but the heart is what also keeps us alive pumping oxygenated blood throughout the body so you could argue both sides.

Answers

Answer: D

Explanation:

Use Darwin’s finches as example they were separated and speciation occurred in the changed beaks

In which situation is speciation MOST likely to occur is few members of the population are isolated from the others.

What can cause speciation?

The speciation process usually occurs due to adverse conditions imposed by the environment. Briefly, two causes are attributed for the process to occur: Geographical Isolation: When lineages of a species separate from the rest of the species for environmental reasons.

In this case, a species no longer identifies with it and thus it isolates itself from its environment.

17. Which of the following best describes how amino acids affect the tertiary structure of a
protein?
a) The number of amino acids determines the tertiary structure of the protein.
b) The interactions of the different R-groups with other R-groups and with their environment
determine the tertiary structure of the protein.
c) The R-group of the last amino acid that is added to a growing polypeptide chain
determines the next amino acid that is added to the chain.
d) The sequence of the amino acids in the polypeptide chain determines the protein's
primary structure but has no effect on its tertiary structure.

Answers

Answer:

It is B

Explanation:

I had this question on my test last week

The tertiary structure of the protein is determined by the interactions of the different R-groups with other R-groups and with their environment in the protein (Option B).

An R-group (also called variable group) is a side chain that is attached to the α-carbon of the amino acids, the building blocks of proteins.

The linear sequence of amino acids within a protein is the primary structure of proteins.

The second structure of proteins is determined by the pattern of hydrogen bonding in the peptide backbone. The most common secondary structures of the proteins are alpha-helices and beta-sheets.

The protein tertiary structure is the 3D (tridimensional) shape of the protein, which is due to interaction among R groups of amino acids and with their environment.

The most common tertiary structures of the proteins are globular and fibrous structures.

Finally, the quaternary structure of the proteins is determined by the interaction of several protein chains or subunits.

In conclusion, the tertiary structure of the protein is determined by the interactions of the R-groups and with their environment in the protein (Option B is correct).

Which of the following nitrogen bases is present only in RNA and not in DNA?

Answers

Answer:

The nitrogen base uracil is only present in RNA. It replaces the Thymine used in DNA and bonds with Adenine.

Explanation:

In the process of photosynthesis, plants use carbon dioxide (CO2), water (H2O), and light energy to produce a sugar (C6H12O6) and oxygen (O2). In the process of aerobic respiration, animals and plants release energy from sugar and oxygen and produce carbon dioxide and water. The chemical equations that describe these reactions look like this: 6CO2 + 6H2O + light C6H12O6 + 6O2 C6H12O6 + 6O2 6CO2 + 6H2O + energy

Answers

The question is incomplete, the complete question is;

In the process of photosynthesis, plants use carbon dioxide (CO2), water (H2O), and light energy to produce a sugar (C6H12O6) and oxygen (O2). In the process of aerobic cellular respiration, animals and plants release energy from sugar and oxygen and produce carbon dioxide and water. The chemical equations that describe these reactions look like this:

photosynthesis: 6CO2 + 6H2O + light ---> C6H12O6 + 6O2

cellular respiration: C6H12O6 + 6O2 ----> 6CO2 + 6H2O + 36 ATP

How do these equations explain why the total amount of O2 and CO2 remains the same?

Answer:

See explanation

Explanation:

If we look at photosynthesis and cellular respiration, we will realize that the both are complementary processes. The product of one process is the input material for the other process.

Respiration and cellular respiration helps to balance the amount of O2 and CO2 in nature because photosynthesis takes in CO2 and releases oxygen while cellular respiration takes in oxygen and releases CO2. This maintains the delicate balance between the both gases in nature.

Describe how the process of natural selection can result in an increase in frequencies of certain traits found in a population.

Answers

An individual may carry a very beneficial genotype with a resulting phenotype that, for example, increases the ability to reproduce

Answer:

Natural Selection (Answer Below)

Explanation:

Natural Selection is the selection of a more beneficial trait. For example, if trees get covered in soot all the white beetles and butterflys are going to stand out like a sore thumb, but the beetles and butterflies that adapted and evolved now have better traits that help them hide predators. The predators have a harder time finding the now black colored butterflies and beetles due to the black soot meaning the beetles and butterflies will have a higher survivability

Give an example of how Eubacteria can be beneficial. Explain. Please help me. ​

Answers

Answer:

Some bacteria are good for you, including the bacteria in your digestive system, or gut. These bacteria help to break down food and keep you healthy. Other good bacteria can produce oxygen are used to create antibiotics. Bacteria are used in food production to make yogurt and fermented foods.

An example of how Eubacteria can be beneficial is that these bacteria fix nitrogen for soil that can be used by living beings.

What are eubacteria?

The bacteria in your gut and digestive tract are among the beneficial bacteria. These microorganisms aid in the digestion of food and promote good health. To make antibiotics, other beneficial microorganisms that can also produce oxygen are employed. Yogurt and other fermented foods are produced using bacteria in the food industry.

Oxygen, carbon, nitrogen, and phosphorus that living things like animals and plants cannot use can be converted by eubacteria into usable forms. In the soil, they fix the nitrogen that is present in the air.

Therefore,  Eubacteria can help the environment by fixing nitrogen into the soil so that living things can use it.

A researcher is comparing sugar molecules that a cell takes in with amino acid molecules that the cell produces. Highlight all the statements that are true about amino acids but not true about sugars,
Always contain carbon
3. an input in glycolysis
C.typically contain nitrogen
D. can be used as an energy source
E can bond together to form proteins

Answers

Answer:

The correct statements for amino acids but not for sugars are :

C. typically contain nitrogen

E can bond together to form proteins

Explanation:

Both Sugars and amino acids always contain carbon molecules and both macromolecules can provide energy so are the source of the energy. Sugar molecule more specifically glucose molecule enters glycolysis during the cellular respiration process.

Amino acids always contain the nitrogen molecule in the structure along with carbon, oxygen, and hydrogen, there is a side chain present. Amino acids are the building blocks of the protein, peptide bonds are formed by amino acids together to make a poly peptide chain of a protein molecule.
