What happens as a result of convection currents in the earth's mantals
Answer:
Inside Earth, the convection of mantle material is thought to cause the movement of the overriding crustal plates, resulting in events such as earthquakes and volcanic eruptions.
Explanation:
Answer: Inside Earth, the convection of mantle material is thought to cause the movement of the overriding crustal plates, resulting in events such as earthquakes and volcanic eruptions.
Explanation: Think of paper on top of a flat plate. If you move the plate in various directions. The paper will also move, but it could be in the same, side to side or opposite direction the current is moving. When the crust or mantle moves. Stress is released causing earthquakes and volcanos erupting with magma from below the very ground you walk on.

Glucose molecules contain stored energy for plants. Glucose is made from carbon dioxide and water molecules during photosynthesis. What kind of energy do plants use to make glucose molecules? A Electrical B Sound C Light D Kinetic
Answer:
The correct answer is - C. light.
Explanation:
In plants, glucose is formed or produces by the process called photosynthesis, a process that uses light energy to produce glucose with the help of carbon dioxide and water.
In this process, light energy is converted into chemical energy stored in glucose or sugars. The process involves light energy, CO2, and water and produces, glucose, and oxygen as a by-product.

What primary method does the cell employ to ensure gene expression only occurs when necessary?
Limited amounts of specific DNA
Phosphorylation cascade with multiple steps
Receptors that only fit specific hormones
Unique transcription factors made of carbohydrates
Answer:
Unique transcription factors made of carbohydrates
Explanation:
Gene expression refers to the way by which the genes which contain hereditary materials in the cells are converted to certain proteins. Gene expression is regulated to avoid the wastage of useful energy. Transcription allows the copying of genetic information from the DNA to the RNA.
Transcription factors can activate or deactivate a gene thus hindering its expression. Unique transcription factors help to regulate gene expression.
Answer: receptors that only fit specific hormones
In snapdragon the gene that affects flower color has two alleles: red (R) and white (W). In heterozygous individuals, the phenotype is pink. If two pink flowers were crossed what would be the probability of a pink offspring?
A. 25%
B. 50%
C. 75%
D. 100%
Answer:
The correct answer is - 50%
Explanation:
In the heterozygous condition, there is always one allele of dominant and one allele of recessive present together and during gamete formation, they assort independently. The probability of the pink flower that is RW can be found by punnet square:
R W
R RR RW
W RW WW
here, out of four two cases is of heterozygous or pink flower so the ration would be 2/4 or 1/2 or 50%
Describe three other features of a bacterial cell.
Answer:
hope it helped
Explanation:
Bacteria are like eukaryotic cells in that they have cytoplasm, ribosomes, and a plasma membrane. Features that distinguish a bacterial cell from a eukaryotic cell include the circular DNA of the nucleoid, the lack of membrane-bound organelles, the cell wall of peptidoglycan, and flagella.
The features of a bacterial cell are the following:
Bacteria are a large group of prokaryotic microorganisms (devoid of cell nuclei) of various possible shapes and sizes.
They are essential in the decomposition processes of organic matter, necessary for the recycling of elements such as carbon or nitrogen.
They reproduce quickly and by asexual procedures, which consist of the replication of the progenitor cell in two exactly equal to it (binary fission).They are made up of a single cell without a cell nucleus, but with a nucleoid (an irregular region where the circular DNA of prokaryotes is found).They have a peptidoglycan cell wall that covers the cell outside the plasma membrane.Scattered throughout the bacterial cytoplasm are ribosomes (in which protein synthesis takes place) and there are also often plasmids (small non-chromosomal DNA molecules).Some bacterial cell also have capsules, a rigid protective structure that is outside the cell wall and flagella to move (if they are mobile).Therefore, we can conclude that bacteria are a large group of prokaryotic microorganisms (devoid of cell nuclei) of various possible shapes and sizes.

How many atoms of carbon, hydrogen, and oxygen are there in the reactants of photosynthesis?
Answer:
The reactants have one carbon atom, four hydrogen atoms, and four oxygen atoms. IN HYDROGEN ATOMS It takes six atoms of carbon (C) and twelve atoms of hydrogen (H) to make one molecule of glucose (C6H12O6). These atoms come from carbon dioxide (CO2) and water (H2O). IN OXGYEN It takes six atoms of carbon (C), six atoms of oxygen (O) and twelve atoms of hydrogen (H) to make one molecule of glucose (C6H12O6).
In photosynthesis, the reactants have one carbon atom, four hydrogen atoms, and four oxygen atoms.
What do you mean by photosynthesis?Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.
Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.
Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants. After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose. These sugar molecules contain the energy that living things need to survive.

In the sample of water, there are 100 atoms of oxygen and 200 atoms of hydrogen. How will the mass of oxygen compare to the mass of hydrogen?
Answer:
The ratio of the mass of an oxygen atom to the mass of a hydrogen atom is therefore approximately 16:1. If we have 2 atoms of each element, the ratio of their masses is approximately 32:2, which reduces to 16:1—the same ratio.
The mass of oxygen compared to the mass of hydrogen is approximately 16:1.
What is a chemical reaction?
There are several types of chemical reactions depending on the reaction mechanisms: combination, single-displacement, double-displacement, combustion, decomposition, combustion and redox reactions.
Thus, 16:1 is the answer.

(a) The oscilation in the pressure inside arteries and arterioles is called by the cardiac rythm. During ventricular systole the pressure rises and during ventricular diastole it decreases
(b)Because when referring to capliaries there is a smaller diameter in the cross section but the surface is bigger. This means that the pressure decreases and the blood has a steady flow instead of periodic bursts.
as cells undergo cellular respiration, what products are produced, and how are they released from the body
Answer:
The cells reproduce The products of cellular respiration are carbon dioxide and water. Carbon dioxide and there released by being transported from your mitochondria out of your cell, to your red blood cells, and back to your lungs to be exhaled
Explanation:
Hope this helped :D
The products that are produced during cellular respiration are carbon dioxide and water. It uses oxygen as a reactant.
Cellular respiration:The process by which organisms take up oxygen and glucose as food molecules and then convert the energy for various activities leads to the formation of waste products like carbon dioxide and water.
