Answer:
The Big Bang theory predicts that the early universe was a very hot place and that as it expands, the gas within it cools. Thus the universe should be filled with radiation that is literally the remnant heat left over from the Big Bang, called the “cosmic microwave background", or CMB.
Explanation:
Answer:
Cosmic microwave background radiation (CMR) found a mysterious microwave a signal causing background noise in the radio telescope the signal came from everywhere. The early universe should have been very hot the cosmic microwave background radiation (CMR) is the remnant heat left over from the big bang.

Explanation:
What is subduction and what causes it?
Answer:
Subduction is a geological process that takes place at convergent boundaries of tectonic plates where one plate moves under another and is forced to sink due to high gravitational potential energy into the mantle. Regions where this process occurs are known as subduction zones.
Explanation:
Environmental catastrophes can cause changes to the Earth’s surface.

A student observes that a plant has droopy leaves and stems and infers that the rate of photosynthesis has slowed in the plant. Which statement provides evidence to support the student’s inference?
Answer:
A. The water pressure in the plant's vacuole is low, and without water, the chloroplasts cannot convert carbon dioxide to glucose during photosynthesis.
Explanation:
Photosynthesis occurs on chloroplasts which are located on the surface of leaves. Photosynthesis is the conversion of carbon dioxide, water, and light energy to produce glucose and oxygen for plants.
The vacuoles inside the plant's cell contain stored food and absorb water through osmosis. Water in the vacuole has more solutes than water outside the vacuole. This causes the Turgor Pressure which the vacuole impacts on the plants. If the reverse becomes the case, water is lost from the vacuole causing it to shrink.
Flaccidity of the vacuole and the cell wall will cause the chloroplasts where photosynthesis occurs to shrink.
During the process of photosynthesis, energy from the Sun is converted into A) chemical energy in the bonds of inorganic molecules B) chemical energy in the bonds of organic molecules like glucose C) enzymes used to produce inorganic molecules D) enzymes used to produce organic molecules
Answer:
b
Explanation:
Photosynthesis is the process of preparing food in the presence of sunlight, water, and carbon dioxide to yield sugar and oxygen.
The correct option is:
Option B. chemical energy in the bonds of organic molecules like glucose
The process of photosynthesis involves:
Photosynthesis is carried out by plants. The leaves are the primary site for photosynthesis. The chloroplasts present in the plant cells are primarily involved in photosynthesis. Photosynthesis involves the capturing of light energy and storing it in the form of bonds of organic molecules like glucose and starch. The process involves carbon dioxide, water, sunlight, and green pigment chlorophyll to carry out photosynthesis. The products of the process are oxygen and sugar molecules holding the energy.
Thus, the correct answer is option B.

Describe some of the properties of water and explain how the structure of water is responsible for these properties.
Answer:
The main properties of water are its polarity, cohesion, adhesion, surface tension, high specific heat, and evaporative cooling. A water molecule is slightly charged on both ends. This is because oxygen is more electronegative than hydrogen. ... The stream of water bends due to the polarity of water molecules.

Answer:
The correct answer is - cell membrane.
Explanation:
Cell membrane or plasma membrane is the outer structure that enclosed the cell-matrix and cell organelles and acts as a barrier to the substances and things to move in or out of the cell and allows only specific substances and molecules to move in and out of the cell.
If the cell membrane is not performing its function properly it might result in blocking the various nutrients and other essential molecules to move in and metabolic substances to move out of the cell.

Cell Membrane

10. How does a right angle (90°) alignment between Earth, the Sun, and the Moon influence the tides on Earth?
a. It produces the greatest change in high and low tides.
b. It produces the least change in high and low tides.
c. It produces semidiurnal tides.
d. It produces diurnal tides.
Answer: The combined gravitational pull of the Sun and moon cause high tides in the path of the alignment, meaning that low tides occur at ninety degrees from the path of the solar eclipse. Due to inertia, the high tides also occur on the opposite side of the Earth from the solar eclipse.

about artificial selection, determine if YOU think the benefits of artificial selection outweigh the disadvantages.
PLEASE HELP!!!!
Answer:
What YOU think
Explanation:
That's what it asks, but here are some points to help you along your way: Artificial selection has brought about the extinction or overpopulation of certain species. This can be seen in the avocado or banana industry. Consumers like the smaller, sweeter species of avocadoes. This caused that species to explode and the old ones to become endangered as farmers grew only that type and bred them selectively. Consumers like the smaller, less mushy, less sweet banana species, so now an amazing species of banana is extinct because the forests that used to have them now no longer exist or were changed to grow only that type of banana. Flip it to the animal side, and it's the same story. Those turkeys that the president "Saves" every year? because of artificial selection, that turkey dies a few weeks later because he grew too plump. Why? Because those turkeys are artificially selected to grow much larger than a normal turkey, and their lifespan is not in mind as they are grown for meat.

RNA interference (RNAI) is a mechanism of gene regulation in eukaryotes. RNAI is initiated by ____, which leads to the ____ of specific genes.
Box 1:
single-stranded RNA
double-stranded RNA
double-stranded DNA
Box 2:
silencing
induction
expression
Answer:
double-stranded RNA; silencing
Explanation:
The RNAi mechanism is a natural process of gene silencing triggered by different small non-coding RNAs such as, for example, siRNAs, miRNAs and piRNAs. RNAi is a powerful technique to induce gene silencing in a sequence-specific manner. The delivery of exogenous double-stranded RNAs (dsRNAs) can be used to induce this evolutionarily conserved mechanism. The dsRNAs first bind to RNAi core components (Ago, Piwi proteins) and then target complementary mRNAs to induce their degradation.
Why do genes in eukaryotic cells have introns?
