Hi, so i was wondering How long does Mars have to travel around Earth to make it's complete rotation?

Answers

Answer:

24 hours and 37 minutes

Explanation:

At Mars' orbital speed of 24 km per second, it takes the planet 24 hours and 37 minutes to complete one rotation. That is just a little more than a day on Earth.

Answer:

The Earth zips around the Sun at about 67,000 miles per hour, making a full revolution in about 365 days – one year on Earth. Mars is a little slower, and farther from the sun, so a full circuit takes 687 Earth days – or one Mars year.

Explain the differences between the three ways of heat transfer, conduction, convection, and radiation.​

Answers

Answer:

The differences between these three ways of heat transfer are that conduction is the transfer of thermal energy through direct contact, convention is the transfer of thermal energy through the movement of liquid or gas, and radiation is the transfer of thermal energy through thermal emission. As you can see, each way of heat transfer has a different way of moving through objects.

Transpiration (the evaporation of water out of the leaves) helps
pull what up through the roots and stems and into the leaves?

Answers

I would say the answer is C

Transpiration helps to pull water and dissolved minerals up through the roots and stems of plants and into the leaves, which is present in the third option as the transpiration creates a negative pressure, or tension, in the leaf tissues.

What is transpiration?

Plants absorb water and minerals from the soil, and these minerals, such as nitrogen, phosphorus, and potassium, are essential for plant growth and development, the roots of plants have tiny, hair-like structures called root hairs, which increase the surface area of the root and help in the absorption of water. Water and minerals are absorbed by the roots to be transported upwards through the plant stem to the leaves, and this transport occurs in specialized vascular tissues called the xylem and the phloem.

Hence, transpiration helps to pull water and dissolved minerals up through the roots and stems of plants and into the leaves, which is present in the third option.

Which of the following occur during interphase? Select all that apply.
A) cells prepare for cell division
B) chromosomes divide
C) cytoplasm divides
D) cells grow rapidly
E) chromosomes replicate

Answers

The cell grows , replicates its dna... I think that’s it sorry if I’m wrong

Cells grow rapidly and hromosomes replicate are occurs during interphase.

What do you mean by interphase?

Interphase is the portion of the cell cycle that is not accompanied by visible changes under the microscope, and includes the G1, S and G2 phases. During interphase, the cell grows, replicates its DNA and prepares for mitosis.

A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.

Interphase is the longest part of the cell cycle. This is when the cell grows and copies its DNA before moving into mitosis. During mitosis, chromosomes will align, separate, and move into new daughter cells.

Which process is part of the carbon cycle?

A. Photosynthesis
B. Transpiration
C. Evaporation
D. Fixation

Answers

Hey there!

Photosynthesis is part of the carbon cycle.

Plants absorb carbon dioxide & sunlight in the middle of the photosynthesis process and create glucose (a type of sugar).

I hope this helps,

have a wonderful day. :)

Photosynthesis is part of the carbon cycle. Therefore option A is correct.

Photosynthesis is a vital process in the carbon cycle, which is the biogeochemical cycle that describes how carbon is exchanged and recycled between the atmosphere, living organisms, oceans, and the Earth's crust.

During photosynthesis, green plants, algae, and some bacteria convert carbon dioxide (CO2) from the atmosphere into organic compounds, such as glucose, using sunlight as an energy source.

This process removes CO2 from the atmosphere, reducing greenhouse gas levels and helping to regulate the Earth's climate.

It is an essential step in maintaining the balance of carbon in the biosphere and plays a significant role in sustaining life on our planet.

Therefore option A Photosynthesis is correct.

C. higher
D. inherited

Answers

Answer: C. higher

Neurological and perceptual speeds are generally higher in individuals with higher intelligence.

Neurological and perceptual speeds are generally found to be higher in individuals with higher intelligence. Thus, the correct option will be C.

What is Neurological and perceptual speed?

Neurological speed can be defined as the speed or how fast the neurons react in the body, how fast a person acquires and processes the information. Neurological speed can be calculated through aptitude tests. These are the tests which are designed to predict a person's future performance and aptitude is the capacity of a person to learn.

Perceptual speed is the speed which indicates the automaticity as well as the efficiency of processing novel visual information and speed of decision-making of a person. Perceptual speed is typically assessed with the speeded tests that require the quick identification of specific targets from a set of stimuli in the body.

Neurological and perceptual speeds are generally higher in the individuals with higher intelligence.

Answers

Answer:

more carbon dioxide would build up without the tress to recycle it and many animals would lose their habitats

Answer:

Animals will begin to migrate towards residential areas if the number of trees on the planet continues to decline, as their natural habitat would be destroyed. There are numerous plant species that can be used as a source of medicine for disease prevention and treatment. Trees provide a significant amount of oxygen to the environment. Some deciduous forest trees grow near rivers, preventing soil erosion by attaching dirt to the plant's roots. Cottonwood, mountain ash, and fruit trees are commercially important trees. If there is a considerable reduction in the quantity of trees, all of the above benefits of trees will be lost.
