A. Do mammals such as humans have a cloaca?

1 answer:

8 0

Most adult placental mammals have no remaining trace of the cloaca. Being placental animals, humans only have an embryonic cloaca, which is split up into separate tracts during the development of the urinary and reproductive organs.

As the question is incomplete and there are no statements available based on which the question can be answered. But based on the knowledge it can be answered.

Answer:

Most of the corals contains photosynthetic algae which are known as zooxanthllae which lives in the tissues of the corals. Algae and corals have mutualistic relationship.

The corals provide algae space to live and algae provides coral food such as glucose and glycerols to them which are considered as products of photosynthesis.

If the producers are hampered by the catastrophic event then the main source of the food will be hampered. There will be less or no food source for the corals which covers a large area in the marine ecosystem.

There are chances that there will be more load on the other photosynthetic organism in water as there will be more population dependent on them for food.

Hence, if there is a loss of habitat for these protist other levels of food chain will be affected due to inter connection.

all plants give out oxygen during day and carbon dioxide during night. Do you agree with this statement. Give reason

Citrus2011 [14]

This statement is incomplete.

"All plants give out oxygen during day and carbon dioxide during night"

Explanation :

Photosynthesis occurs only during day time.

During this time oxygen is produced . Some oxygen is used for respiration and rest of oxygen is diffused out into air.

Carbon dioxide produced during day time by respiration is used in photosynthesis.

But at night time, no photosynthesis occurs and hence no oxygen is produced oxygen from air diffuses into leaves to carry out respiration and carbon dioxide produced by respiration diffuses out into air.

Hence Respiration occurs day and night .. Hence Carbon dioxide is emitted all the time....

Explain how dysfunction at one level of organization impacts other levels and provide an example.

Nuetrik [128]

Answer:

Please find the explanation below

Explanation:

All living organisms are made up of four level of organizations namely: cell, tissue, organs, organ system and ultimately, the organism. These levels of organization are interrelated in such a way that CELLS accumulate to form TISSUE, TISSUES accumulate to form ORGAN, ORGANS accumulate to form ORGAN SYSTEM.

Since one level is dependent on a lower level, a dysfunction in one level will cause the dysfunction of another level. For example, a dysfunction in LIVER CELLS will cause the LIVER TISSUES formed from the cells to be dysfunctional. This dysfunctionality will extend to the LIVER as an organ and cause issues in the EXCRETORY SYSTEM (an organ system that constitutes the liver organ).

How do living things make use of the energy stored in food molecules?

ipn [44]

Answer:
The energy stored in food molecule (glucose) is released in he process of respiration.

Explanation: Respiration is a cellular process in which glucose molecule is broken down into carbon dioxide, water and ATP is produced as end product. Respiration consists of following main steps:
1. Glycolysis: It occurs in the cytoplasm of cell, and each glucose molecule is converted into two pyruvates with help of ATP.
2. Formation of Acetyl coenzyme A: It is a connecting link reaction between glycolysis and Kreb cycle. In this phase Each pyruvate react with Coenzyme A to become acetyl coenzyme A.
3. Kreb Cycle: It occurs inside mitochondria. In this cycle each acetyl coenzyme A with fixed with CO to produce citrate which undergo in a cyclic reaction to produce ATP and NADH. .
4. Electron transport chain: It is the last step of respiration which complete in mitochondrial membrane. In this phase most of the energy is produced along with H₂O as by product.
