How does deforestation affect coral reefs?

Answers

The world's coral reefs are being damaged by harmful runoff, which new research shows is being caused by the clearing of forests. Preventing soil erosion may help protect the reefs, which shield coastlines from ocean waves, draw tourists with their brilliant colors and provide a habitat for fish.

For centuries, humans around the world have been clearing away forests to make room for livestock, farming, and other uses. Scientists say that when the forest cover is lost, soil washes away into rivers that flow into the oceans and, they believe, onto coral reefs.

That runoff adds nutrients to the ocean water. It's essentially too much of a good thing, and scientists have long suspected it can kill the coral. Runoff also clouds the water, blocking light from reaching the reef.

Answer: When the forest cover is lost, soil washes away into rivers that flow into the oceans and, they believe, onto coral reefs. That runoff adds nutrients to the ocean water.

Explanation: Basically, when this occurs, the roots are no longer attached to the soil, letting all the nutrients get ruined in the ocean water instead of feeding plants/animals/trees.

A student collects a sample of water from a pond near her home. She
examines a drop of the water under a microscope and sees four very
differently shaped single-celled organisms. Which of the following
can she reasonably conclude as the reason the organisms look so
different?

Answers

Answer:

A. Each organism had a different parent that passed on a set of unique genetic instructions.

Explanation:

Organisms can either be single-celled or multicellular. According to this question, a student collects a sample of water from a pond near her home. She then examines a drop of the water under a microscope and noticed it contains four very differently shaped single-celled organisms.

The single-celled organisms are of different shapes because they are from different parents, which passed on a set of unique genetic instructions via their genes to them. Organisms of the same species from the same parent will possess the same shape because they contain same gene which makes them look and behave similar.

However, in this case, the four different shaped single-celled organisms are of DIFFERENT SPECIES and hence, contain individual unique genes that makes them so

Answers

Adenine and Thymine are examples of nitrogenous bases in a nucleotide.

What is a nucleotide base?

A nucleotide is the monomer constituting DNA or RNA biopolymer molecules.

Each nucleotide consists of a nitrogenous heterocyclic base (or nucleobase), which can be either a double-ringed purine or a single-ringed pyrimidine; a five-carbon pentose sugar (deoxyribose in DNA or ribose in RNA); and a phosphate group.

The two classes of nitrogenous bases are purines and pyrimidines and they are as follows;

Purines - Adenine and GuaninePyrimidines - Cytosine, Uracil, Thymine

According to this question, Adenine and thymine are examples of nitrogenous bases.

What is cellular respiration ?

A series of chemical reactions known as cellular respiration break down glucose into ATP, which can be used as energy to power numerous body processes. Cellular respiration has three main stages: the citric acid cycle, glycolysis, and oxidative phosphorylation. The citric acid cycle takes place in the mitochondrial matrix, glycolysis takes place in the cytosol, and oxidative phosphorylation takes place on the inner mitochondrial membrane. Glucose, ATP, and NAD+ are the cellular respiration starting reactants, the rate-determining enzymes for cellular respiration are phosphofructokinase-1, pyruvate dehydrogenase, and isocitrate dehydrogenase, and the final products include ATP and water. One or more enzymes involved in cellular respiration, like succinyl-CoA-synthase or pyruvate kinase, are typically disrupted by diseases that affect this process.Glycolysis is the only process that can take place without oxygen, and only two ATP molecules can be produced for each glucose molecule. ATP and H2O are the two final end products of cellular respiration. Glycolysis produces two pyruvate molecules, four ATPs (a net of two ATP), two NADH molecules, and two H2O molecules.One acetyl-CoA, one NADH, and one CO2 are produced for each pyruvate molecule when oxygen is present. One GTP, three NADH, one FADH2, and two CO2 are the products of the TCA cycle. GTP is an energy-rich compound similar to ATP that is typically used in environments with lower pH. The electron transport chain can then use NADH and FADH2 to make more ATP as part of oxidative phosphorylation.
