Patients wear protective gear when being X-rayed. What substance is being protected directly from mutation?
Answer:
Radiation has a potential of causing germ cell mutations that may be passed on to future generations.
Explanation:
i think so, hopefully this helps;(
Ionizing radiation damage cells and cause double-strand breaks that let more DNA in. These additional fragments of DNA find their way to the nucleus and cause cellular mutations. Protective gears are worn to prevent this.
What are X-rays ?X-rays are a form of electromagnetic wave radiation. Using X-ray imaging, your body's interior can be visualized. The photos depict the various bodily parts in various shades of black and white. This is due to the fact that various tissues absorb radiation in different ways.
Ionizing radiation, a type of radiation that x-rays create, has the ability to destroy living tissue. This is a risk that gets worse the more exposures someone has over the course of their lifetime. However, exposure to radiation normally carries a low risk of acquiring cancer.
Therefore, protective gears are worn during x-rays to avoid mutations.

Which product of respiration is considered waste material and leaves the alveoli?
O oxygen
O water
O carbon dioxide
O carbon monoxide
Answer:
In our respiratory system, carbon dioxide is the waste material that we expel when we breathe out. The answer is C, Carbon Dioxide
I hope you have a great day!
The waste product of respiration is
C. Carbon dioxide
The oxygen consumed via stomata is used up by cells.
Respiration in leaves:Oxygen from the air enters a leaf through stomata and reaches all the cells by the process of diffusion. This oxygen is used in respiration in cells of the leaf. The carbon dioxide produced during diffuses out from the leaf into the air through same stomata. The oxygen used by cells in the leaves to disintegrate glucose into water and carbon dioxide.
Thus, option C is correct.

. A protease is added to a suspension of egg protein in a test-tube and kept at 37°C. After 8 minutes, the protein changes from cloudy to transparent. Which product, or products, will now be present in the test-tube
Answer:
amino acids
Explanation:
A protease is an enzyme capable of catalyzing the breakdown of proteins into polypeptide fragments and single amino acids, which are the building block of proteins. Proteases act by breaking peptide bonds by a process called hydrolysis, a reaction where water molecules break down peptide bonds (hydro means water and lysis means split). Proteases can be classified depending on the catalytic residue into cysteine, serine, threonine, aspartic, glutamic and metalloproteases.
The product that will be present in the test tube will be amino acids.
Protease is an enzyme that acts on protein by converting it into different
types of amino acids.
Amino acids are referred to as the building block of life and are important
nutrients in growth and replacement of worn-out tissues. The protease acts
on the protein by breaking the peptide bonds under the required
temperature.
An inadequate temperature may result in the denaturing of the enzyme
which was why the test was done at 37°C. This is the body temperature of
humans which led to the formation of amino acids which is absorbed by cells
of the body.

Protein is found throughout the body—in muscle, bone, skin, hair, and virtually every other body part or tissue.
What is protein?It makes up the enzymes that power many chemical reactions and the hemoglobin that carries oxygen in your blood. At least 10,000 different proteins make you what you are and keep you that way.
Protein is made from twenty-plus basic building blocks called amino acids.
Because we don’t store amino acids, our bodies make them in two different ways: either from scratch, or by modifying others. Nine amino acids—histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine—known as the essential amino acids, must come from food.
Therefore, Protein is found throughout the body—in muscle, bone, skin, hair, and virtually every other body part or tissue.

What caused the chromosomal alteration in the number 21 chromosomes? (LS3.2) A. Part of one chromosome attached to another chromosome B. Some of the genes on a chromosome were reversed C. A duplicated chromosome failed to separate during meiosis D. A part of a chromosome was lost
Answer:
The correct answr is - A. Part of one chromosome attached to another chromosome.
Explanation:
Translocation is one of the chromosome abnormality that cause change in the number of the chromosome. In the translocation a part of the chromosome breaks off and bind or attached to the another chromosome.
The translocation cause various disorderes in individual one of them is Down syndrome which is the result of the alteration of chromosome number 21. In this translocation or specicifically the chromosome portion of chroromosme 14 breaks off and reattaches to the chromosome 21 result in one normal 14 and two normal 21 chromosme so there is trisomy occurs.
Answer:
A duplicated chromosome failed to separate (nondisjunction)
Explanation:
If nondisjunction occurs during meiosis I, homologous chromosomes fail to separate. This produces abnormal gametes that contain two members of the affected chromosome or none. This is why there is an extra chromosome in the 21 chromosomes.

Hope this helps!
If a plant cell needs energy for endocytosis, its use and energy come from- Active transport from ATP.
Endocytosis is an energy-using process by which cells internalize molecules by engulfing them.
Endocytosis needs to use directly ATP to fuel the transport of large particles such as macromolecules, parts of cells that can be engulfed by other cells in a process called phagocytosis.Active transport is the movement of molecules across a cell membrane in the direction against their concentration gradient, i.e., moving from a low concentration to a high concentration and this uses cellular energy.Thus, If a plant cell needs energy for endocytosis, its use and energy come from- Active transport from ATP.

What are biomes?Since they belong to certain areas or zones that, due to their geographical characteristics, share a climate, vegetation, and wildlife, biomes provide the primary support for the harmony of nature.
Any biome can include a wide range of habitats because the term "biome" is more general than "habitat." An area's climate and geography determine the biome classification. Communities that have adapted to the unique climate and ecology of the biome make up each one. Depending on the surroundings, they come in a variety of forms. The temperate deciduous biome is the ideal environment for human habitation.

Answer:
an estuary
Explanation:
A wetland which contains a mixture of fresh water and salt water is called as an estuary. Thus, the correct option is A.
What is an estuary?An estuary is an example of a partially enclosed, coastal water body where the freshwater from rivers and streams mixes up with the salt water from the ocean bodies. Estuaries, and their surrounding lands, are the places of transition from the land area to the sea area.
Estuaries and their surrounding wetlands are the bodies of water which are usually found where the rivers meet the sea. Estuaries are the home to many of the unique plant and animal communities which have adapted to the brackish water, which is a mixture of fresh water draining from the land and the salty seawater.

Explanation:
Los ARN mensajeros, también conocidos como ARNm, son uno de los tipos de ARN que se encuentran en la célula. Éste en particular, como la mayoría de los ARN, se sintetiza en el núcleo y luego se exporta al citoplasma, donde la maquinaria de traducción, la maquinaria que realmente fabrica las proteínas, se une a las moléculas de ARNm y lee en ellas el código para producir una proteína específica. Así que en general, un gen, el ADN de un gen, puede ser transcrito en una molécula de ARNm que puede acabar dando lugar a una proteína específica.
