Hi!

Epithelial cells (I believe) Nervous SystemSkeletal System

Explanation:

Epithelial tissue helps cover your "exterior sources". Therefore I'm pretty sure the first one is Epithelial cells.The Nervous System has to do with sense of feeling or sense of touch mostly. The Nervous System controls everything you do!                                     ex. touching a table uses the nervous system.The Skeletal System helps your body move and supports a lot of different things in your body. All of those other options are not correct just because they do not support. Here is what I mean in the shortest way possible:Circulatory- has to do with your lungsLymphatic- involves a network of vesselsExcretory- elimination of waste

Therefore these are your answers #1, #2, and #3.

Hope this helps!

Explanation:

Osmosis is the movement of the solvent in a solution into the higher concentration are of solute through the semipermeable membrane such as cell membranes.

Which best describes the cycle that ensures fresh water, which is vital for carrying out metabolic processes, is available?

A.
carbon emission, photosynthesis, respiration

B.
evaporation, condensation, precipitation

C.
evaporation, respiration, transpiration

D.
run-off, precipitation, flooding

Answers

Answer: B.  evaporation, condensation, precipitation

Explanation:

The Hydrological Cycle is the process by which water moves from the surface to the atmosphere and then back again. It is important for various reasons one of which is that it is vital for carrying out metabolic processes.

The cycle involves the evaporation of water from the surface which turns water into water vapor. This vapor then becomes liquid and forms clouds when it gets to the atmosphere in the condensation process.

It then falls back down to the surface when the clouds formed become too heavy in the process of precipitation/ rain.

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.

Sam wished to investigate how fertilizer run-off affects the growth of algae in freshwater lakes and streams. He set his experiment up as follows. He placed 900 ml of water into each of five 1000 ml glass beakers. To each beaker, he added 5 ml of water from an aquarium which contained a large concentration of algae. The beakers were placed under a lamp which was on a timer to provide 12 hours of light each day. Liquid fertilizer was added to the beakers in the following amounts.

Each week, a random sample from each of the beakers was examined under a microscope to get a count of the number of algal cells present.

In mice, there are three options for fur color: black,grey and white. What type of inheritance is shown by these mice?

A. Simple
B. Co-dominance
C. Incomplete dominance
D. Sex linked inheritance

Answers

Answer:

C. Incomplete dominance

Explanation:

Incomplete dominance is a type of non-mendelian inheritance in which one allele does not completely mask the phenotypic expression of the other allele in a gene, hence, the blending of both alleles give rise to an intermediate third phenotype.

According to this question, there are three options for fur color in mice namely: black, grey and white. This is so because the alleles for black and white coloration exhibits INCOMPLETE DOMINANCE, hence, they produce a third phenotype (grey) that is a blend of both parental phenotypes.

The reaction of cellular respiration involves the use of the glucose molecule in presence of oxygen to produce energy and carbon dioxide. Thus, option B is correct, as molecule B is carbon dioxide.

What is cellular respiration?

Cellular respiration is a chemical method that involves the inhaled oxygen and use of the food molecules to release energy along with the water and carbon dioxide molecules.

Cellular respiration can be depicted by the reaction:

C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy

Therefore, molecule B is carbon dioxide.

Trees, such as those in the deciduous forest, are very important to the environment. If the number of trees on earth continues to decrease significantly, what might be the result? (Site 1)​

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.
