write paragraph about digestion of food in brief
Answer:
Digestion is the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma. In certain organisms, these smaller substances are absorbed through the small intestine into the blood stream.
Explanation:
according to wikipedia!
Digestion is nothing but breaking down of substances into simpler forms, which the body can use. We eat many things and they have very complex compounds, our body cannot use these compounds. So, different parts of our digestive system breaks down different compounds to simpler forms, so that our body can use it for different functions.

The diploid number for the tasmanian devil is.
Answer:
14.
Explanation:
A Tasmanian Devil has a diploid number of chromosome which is 14 while on the other hand, there are 7 number of chromosomes in the sex cells. The sex cells i.e. sperm and egg has haploid number of chromosome so the number of chromosomes in sex cells of Tasmanian Devil is 7 while on the other hand, in the somatic cells or body cells there is diploid means double number of chromosome so the diploid number of chromosome for Tasmanian Devil is 14.

Describe sea turtle populations during the late 1400’s
Answer:
6.5 million sea turtles
Recent estimates show us that there are nearly 6.5 million sea turtles left in the wild with very different numbers for each species, e.g. population estimates for the critically endangered hawksbill turtle range from 83,000 to possibly only 57,000 individuals left worldwide.

IMPORTANCE OF ENZYMES??
Answer:
Enzymes create chemical reactions in the body. They actually speed up the rate of a chemical reaction to help support life. The enzymes in your body help to perform very important tasks. These include building muscle, destroying toxins, and breaking down food particles during digestion.

Hope this helps
Answer:
An ecosystem must contain producers, consumers, decomposers, and dead.All ecosystems require energy from an external source and that would be the sun.Plants need sunlight to photosynthesise and produce glucose, providing an energy source for other organisms.

A researcher crossed two plants, and informed an assistant researcher to determine the genotypes and phenotypes of the plants that were crossed by analyzing the offspring. The assistant counted 30 plants with green pods and 10 plants with yellow pods. Which of the following conclusions can accurately be made by the assistant?
a. The researcher had selfed a true-breeding plant with green pods.
b. The researcher had crossed true-breeding plants of differing pod colors.
c. The researcher had crossed two heterozygous plants.
d. The researcher had crossed two plants with yellow pods.

Darwin’s finches evolved on an island. What is the main reason that islands often provide good examples of evolution?
Answer:
They allow for automatic biogeographic isolation. In rock layers, jellyfish fossils are found lower than trilobite fossils, and trilobite fossils are found lower than ammonite fossils.

4. The inner membrane of the mitochondria is impermeable to ions. How does this fit with what
you've learned about membrane structure? Why is this important to cellular respiration?
Answer:
The inner mitochondrial membrane contains proteins involved in the electron transport chain. This chain releases energy that is then used to generate an electrochemical gradient, which is subsequently used to synthesize ATP
Explanation:
Mitochondria are membrane-bound organelles that have an inner membrane separated from an outer membrane by the intermembrane space. Moreover, the mitochondrial matrix is located within the inner membrane. The inner mitochondrial membrane contains proteins involved in the electron transport chain and ATP synthesis. Oxidative phosphorylation (electron transport chain) is the third stage of cellular respiration in aerobic organisms in which ATP is generated by transferring electrons from NADH or FADH2 to O2 by a series of electron carriers located in the inner mitochondrial membrane. The trans-membrane complexes of electron carriers are multiprotein enzyme complexes (I–V) and electron carriers (i.e., coenzyme Q10 and cytochrome c) required for the communication between complexes. The electron transport chain is coupled to proton transfer from the matrix out to the intermembrane space, thereby generating a proton gradient which is then used by ATP synthases to synthesize ATP.
what will most likely happen if a population is large and no migration, mutation, or environmental change occurs?

Ari drew a diagram to show organisms in an ecosystem.
A flowchart. Cycle 1: 1, Grass. 2, Grasshopper. 3, Shrew or Mouse. 4, Fox. Cycle 2: 1, Grass. 2, Mouse. 3, Fox or Snake. Cycle 3: 1, Grass. 2, Rabbit. 3, Fox.
What did Ari draw?
a food chain
a trophic chain
a food web
an energy web
Answer: Ari draw a food web.
Explanation:
A single ecosystem which contains all the food chains is called a food web.
In a food web each living thing present in a food web is a part of multiple food chains. Hence, food webs tend to represent the overlapping of food chains in that ecosystem.
The flow chart drawn by Ari represents that the living things present in cycle 1 are part of cycle 2 and cycle 3. Also, living things present in cycle 2 are part of cycle 1 and cycle 3.
A food chain is basically a single path where each organism is dependent of the other as a source of food without any overlapping.
Thus, we can conclude that Ari draw a food web.
