Answer:
Muscular contractions
Explanation:
The muscles contract when the food is moved through the digestive tract
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.In conclusion, food is moved through the digestive tract primarily by muscular contractions (Option C).

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

What is the complementary RNA sequence for the DNA sequence ATA
CGC TAA*
DIRECTIONS: Drag & drop to complete the sentences below describing the flow of genetic information in cells.
___ 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 ___.
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)
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.

The blocks above represent ecosystems, with each species type designated by a different color. Which block represents the greatest diversity?
1
2
4
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.
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.

ecosystem. He observes that coyotes hunt and kill white-tailed deer. He learns
that lungworms live in the lungs of the deer, making it difficult for the deer to
breathe. He also learns that larvae of nasal bot flies live in the nasal passages of
the deer and cause them minor harm. Which sentence describes the lungworms
and fly larvae? *
They are both hosts.
They are both predators.
They have different niches in the same habitat.
They compete for the same resources in a shared niche.
Explanation:
they compete for the same resources in a shared niche because the coyote hunts for the deer, and the coyote killed the white-tailed deer
can i get 10 ways to help the environment/earth
Answer:
1. Reduce, reuse, and recycle. Cut down on what you throw away. 2. Follow the three "R's" to conserve natural resources and landfill space.
3. Volunteer. Volunteer for cleanups in your community. You can get involved in protecting your watershed, too.
4. Educate. When you further your own education, you can help others understand the importance and value of our natural resources.
5. Conserve water. The less water you use, the less runoff and wastewater that eventually end up in the ocean.
6. Buy less plastic and bring a reusable shopping bag.
7.Use long-lasting light bulbs. Energy efficient light bulbs reduce greenhouse gas emissions. Also flip the light switch off when you leave the room!
8. Plant a tree. Trees provide food and oxygen. They help save energy, clean the air, and help combat climate change.
9.Don't send chemicals into our waterways. Choose non-toxic chemicals in the home and office.
10.Bike more. Drive less.
