Muscular contractions

Explanation:

The muscles contract when the food is moved through the digestive tract

Answer 2

Food is moved through the digestive tract primarily by muscular contractions (Option C).

What is digestion?

Digestion refers to the physiological process where foods are absorbed and assimilated by the digestive system.

During digestion, foods are moved across organs through smooth muscle contractions.

The smooth muscle is an involuntary muscle associated with peristaltic movements during digestion.

Which chemical is LEAST persistent in
the environment?
A. Radon
B. Agent Orange
C. PCBs
D. DDT

Answers

Answer:

D. DDT

Explanation:

DDT is highly persistent in the environment means that it break down very slowly in the environment. The half-life for DDT is from 2 to 15 years. Half-life is the time needed for the degradation of half of the compound. Persistent bio-accumulative toxic substances (PBTs) are chemicals that break down slowly in the environment and its accumulation in living organisms are toxic. Some PBTs are dispersed through air currents while some uses other environmental pathways, resulting in contamination of regions far from their points of origin.

If it is true that global warming is causing climate change, why can't animals adapt to the new conditions?

Answers

Answer

they're cool blooded and they can die can't find food

Explanation:

Answer:

Animals can adapt to the new conditions OVER TIME. But, at the rate at which climate change is occuring, there is not enough time for animals to evolve in a way that will keep their species alive. Evolution takes a long time, it doesn't happen over night. On top of that, many oceans are becoming acidic and are losing oxygen faster than marine animals can evolve.

___ is the process of recording the base sequence from DNA into mRNA, which takes place in the ___. ___ is the process of assembling a protein from an mRNA transcript, which takes place in the ___.

Answers

Answer:

- Transcription, nucleus

- Translation, cytoplasm (ribosome)

Explanation:

Two major processes are involved in the expression of a gene in living organisms and they are: transcription and translation. Transcription is the process whereby mRNA transcript is synthesized from a DNA template. In the process of transcription which occurs in the NUCLEUS, the base sequence from DNA is recorded into the mRNA.

On the other hand, translation is the process whereby the mRNA transcript is used to synthesize an amino acid sequence. In other words, translation involves the process of assembling a protein from an mRNA transcript in an organelle called RIBOSOME located in the cytoplasm.

Describe what the purpose of your reforestation efforts is in combating climate change and describe how it works

Identify the part(s) of the world that are currently planning or doing reforestation efforts

Explain how reforestation efforts will directly combat climate change (how will the action reduce the causes and/or negative effects of climate change)

Answers

Answer:

Reforestation offers one of the best ways to remove carbon dioxide from the atmosphere, turning it into solid carbon through photosynthesis and storing it in tree trunks, branches, roots, and soil.

The countries that have the most forest-ready land are: Russia, Canada, Brazil, Australia, United States and China. The four major strategies are: Increase the amount of forested land through reforestation. Increase density of existing forests at a stand and landscape scale.

We estimate that reforestation since 2000 is on pace to remove 103 billion tons of carbon dioxide from the atmosphere between 2020-2050. Increasing the pace of tropical reforestation would remove substantial amounts of additional carbon dioxide at low cost.

Answers

Sorry if I’m wrong but I believe it’s 5

Answer: The answer is 5 (D)

Explanation:

   Block 1 has only 1 different type of species

   Block 2 has only 2 different types of species

   Block 3 has only 2 different types of species

   Block 4 has only 3 different types of species

   However Block 5 has 3 different types of species, but they are all of equal size or abundance.

In Block 4 pink and blue are a minority and so the species abundance is low (while the species richness is equal to block 5), block 5 has a higher species abundance and an equal species richness than block 4.

Distinguish between tissue fluids and lymph. With their correct definitions.

Answers

Answer:

Tissue fluid consists of water, ions, and dissolved gases and food substances, which is formed when blood is ultrafiltered from the capillaries into the intercellular spaces. The tissue fluid surrounds the body cells, facilitating the exchange of nutrients and waste materials. It helps bring oxygen and nutrients to cells and to remove waste products from them. As new tissue fluid is made, it replaces older fluid, which drains towards lymph vessels.

Lymph is a colorless fluid containing white blood cells, which bathes the tissues and drains through the lymphatic system into the bloodstream. It is essentially tissue fluid that has entered a lymphatic capillary. Lymph formation depends upon tissue fluid formation.

Explanation:

Answer:

Tissue fluid ensures the supply of materials, nutrients, oxygen into the cells in tissues and organs, and removal of metabolic wastes from tissues. Lymph: Lymph is involved in the removal of metabolic wastes and infectious organisms from tissues.

many of the molecules found in the body are organic.
A: make an argument for which three biological molecules you feel are the most important for the body.
B: water is inorganic but still essential. could humans live without water? why or why not?​

Answers

A. The three most important biological molecules are proteins, nucleic acids, and carbohydrates. Proteins are responsible for signaling receptors and play a key role in DNA production. Nucleic acids, similar to proteins, make up our DNA and make us who we are. Carbohydrates provide us with energy and help our body function.

B. We’ve become so dependent on water that I’d say it’s impossible for humans to live without it. At the most fundamental level, everything we consume — both literally and metaphorically — contains or utilized water. Our favorite foods, drinks, and even buildings contain a percentage of water. Maybe things would be different if we hadn’t allowed it to play such an essential role in practically everything we use, but they aren’t. We need water, which is why going 2 weeks without water could kill us. Sure, there are substitutes for water like milk, but milk is not as good for us as water is. Water balances and purifies our body, while milk fills it up with more waste.
