Answer:
Normally, the flexible, round red blood cells move easily through blood vessels. In sickle cell anemia, the red blood are shaped like sickles or crescent moons. These rigid, sticky cells can get stuck in small blood vessels, which can slow or block blood flow and oxygen to parts of the body.
Hope this helps :)

Biochemistry involves the production and degradation of biological molecules such as nucleic acids, proteins, lipids, carbohydrates, and vitamins. Changes in the production or degradation of these important molecules can cause disorders and diseases in humans. For each of the human disorders and diseases listed below, indicate whether it is caused by a change in: (A) nucleic acids (for example: DNA or RNA); (B) amino acids/proteins; (C) lipids (for example: cholesterol or triglycerides); (D) carbohydrates/sugars; or (E) vitamins. Provide only one (1) answer for each disease.
Answer:
Disorders are present below.
Explanation:
Degradation of nucleic acids causes Lesch-Nyhan syndrome and mitochondrial depletion syndromes in human body, degradation of proteins causes phenylketonuria and tyrosinemia diseases in humans, degradation of lipids causes Gaucher disease and Tay-Sachs disease. Due to these diseases of lipids, we have not enough enzymes to break down lipids, degradation of carbohydrates leads to diabetic ketoacidosis, hyperosmolar coma and hypoglycemia, and degradation of vitamins causes anemia and scurvy diseases in the body.
the movements of energy and nutrients through living systems are different because
Answer: energy flows in one direction, and nutrients recycle.
Explanation:
The options are:
• energy flows in one direction, and nutrients recycle.
• energy is limited in the biosphere, and nutrients are always available.
• nutrients flow in one direction, and energy recycles.
• energy forms chemical compounds, and nutrients are lost as heat.
There's difference between the movements of energy and the nutrients through living systems due to the fact that energy flows in one direction, and nutrients recycle.
In order to maintain ecological balance, it should be noted that the energy flow in the ecosystem is vital. The producers produces the food through photosynthesis.
Then, energy is passed from one trophic level to another trophic level. Energy flows in only one direction which brings about the difference in the movements of energy and nutrients through living systems

How can you tell from a food web which organisms will have the greatest biomass?
Answer:
You can tell by which animals are at the top of the food chain.
Explanation:
You can tell this because if you count all the biomass below the animals at the top of the food web (which eat all the biomass below it), there is much more biomass below these animals (the ones at the top of the food chain), than any other animal below it. For example, if the rat ate a grasshopper it will receive its biomass, but if the python then eats the rat, then the python will be getting the biomass of the rat and the grasshopper, compared to the rat just getting the biomass of the grasshopper. So since there is much more biomass below the animals at the top of the food web, this means that the animals at the top of the food web receive the most biomass (when they eat the animals below them) out of the whole food web individuals.

Given below are a few activities carried out by agricultural farming.
1. Adding fertilizer or manure to the soil.
2. Removing the husk to feed cattle.
3. Removing weeds from the field
Which of the above helps to increase the amount of nutrients available to the crop plant?
A) Only 1 b) Only1 and 2
c) Only 1 and 3 d) All: 1, 2. And 3
Answer:
Adding fertilizer or manure to the soil.
Explanation:
This is because fertilizer or manure are formulated substance that contain different nutrients which when applied to the soil will add nutrients to the soil and make nutrients available for plants absorbing and these nutrients absorbed will help improve yield. They contain nutrients that help boost plants growth.

1. Catalytic converters reduce which of the following pairs of pollutants in car exhaust? a.)Carbon dioxide and ozone
b.)Carbon monoxide and hydrocarbons
c.)Carbon dioxide and particulates
d.) Lead and mercury
e.)Methane and particulates
Answer: B
Explanation: By most estimates, catalytic converters fitted inside the exhaust pipe of a gasoline-operated car convert over 90% of hydrocarbons (HC), carbon monoxide (CO) and nitrogen oxides (NOx) from the engine into less harmful carbon dioxide (CO2), nitrogen and water vapour.
The catalytic converter used in the exhaust of the cars reduces carbon mono oxide and hydrocarbons.
What is a catalytic converter?The catalytic converters are the devices used in the exhaust of the vehicles run on petrol and diesel.
They convert the harmful toxic gases into the less harmful pollutants by a redox reaction.
By most estimates, catalytic converters fitted inside the exhaust pipe of a gasoline-operated car convert over 90% of hydrocarbons (HC).

Which of the following is believed to be common among all mass extinction events?(1 point)
a significant change in the global climate
the type of species that went extinct
the type of event that causes the extinction
the number of species that went extinct
Answer:
D the type of event that causes the extinction
The correct answer is a significant change in the global climate, as due to this is believed to be common among all mass extinction events.
Climate extrude interacts with threats which include habitat loss and overharvesting to similarly exacerbate species declines. The decline of species and ecosystems can then boost up weather extrude, growing a remarks loop that similarly exacerbates the situation.
What is global mass extinction?The mass extinction is an end result of human activity, pushed through populace boom and overconsumption of the earth's herbal resources. The 2019 international biodiversity evaluation through IPBES asserts that out of an expected eight million species, 1 million plant and animal species are presently threatened with extinction.
Therefore it is clear that a significant change in the global climate is believed to be common among all mass extinction events.

what function does DNA performs in eukaryotes
Answer:
DNA is the information molecule. It stores instructions for making other large molecules, called proteins. These instructions are stored inside each of your cells, distributed among long structures called chromosomes. These chromosomes are made up of thousands of shorter segments of DNA, called genes.
Explanation:
Function of DNA is that it stores all the coded information for the function of the cell and the cells role in the development of a multi cellular organisms.
Where is DNA in eukaryotes?In nucleus the eukaryotes, the cell's genetic material, or DNA, is contained within an organelle called the nucleus, where it is organized in long molecules called chromosomes.

1c) If the amino acid sequences in the proteins of 2 organisms are similar, why will their DNA also be similar?
Answer and Explanation:
Because the DNA sequence determines a protein's amino acid sequence, a gene shared by two closely related organisms should have similar, or even identical, amino acid sequences. That's because closely related species most likely diverged from one another fairly recently in the evolutionary span. Thus, they haven't had as much time to accumulate random mutations in their genetic codes.
