Alvin is propelled by ____ hydraulic thrusters and features an electrical system powered by lead-acid batteries. *
Answer:
Alvin is propelled by _gas or diesel___ hydraulic thrusters and features an electrical system powered by lead-acid batteries.
Explanation:
Technically, this implies that Alvin is working on motor-assist mode, using a hybrid engine. Alvin is, therefore, propelled by an internal combustion engine (given the presence of hydraulic thrusters) in addition to an electric motor, which uses energy stored in (lead-acid) batteries. Alvin must be a robot.
If u know the water cycle please answer this question
Answer:
Gravity
Explanation:
Percolation is the process of a liquid slowly passing through a filter. It's how coffee is usually made. Percolation comes from the Latin word percolare, which means "to strain through." Percolation happens when liquid is strained through a filter, like when someone makes coffee.
Evaporation-the process of turning from liquid into vapor.
Condensation-water which collects as droplets on a cold surface when humid air is in contact with it.
and gravity- Gravity is the force of attraction between two objects, and Earth's gravity pulls matter downward, toward its center. It pulls precipitation down from clouds and pulls water downhill. The warm water near the surface of the ocean heats up with sunlight and evaporates, keeping the water cycle in motion.
What is the most common method used to count a large species population

If the process illustrated in the diagram is interrupted by a chemical at point X, there would be an immediate effect on the release of
1) Chlorophyll
(2) carbon dioxide gas
(3) nitrogen gas
(4) oxygen gas
Answer: oxygen
Explanation:
If the process illustrated in the diagram is interrupted by a chemical at point X, there would be an immediate effect on the release of oxygen gas.
What is chloroplast?Photosynthesis, the process by which light energy is transformed to chemical energy and results in the generation of oxygen and energy-rich organic compounds, takes place in the chloroplast, a structure found inside the cells of plants and green algae.
Close relatives of chloroplasts that are free-living are photosynthetic cyanobacteria; according to the endosymbiotic theory, these organisms are the ancestors of both chloroplasts and mitochondria, which are eukaryotic cells' energy-producing organelles.
Therefore, If the process illustrated in the diagram is interrupted by a chemical at point X, there would be an immediate effect on the release of oxygen gas.

Stagnant, shallow areas of water-saturated soil, where the rate of photosynthesis is low, are best characterized as:______.
Answer:
The correct answer is - bogs.
Explanation:
Bogs or boglands is a wetland that is made up of dead organic matter such as dead plants or parts of the plants like mosses, majority time it is a thick carpet of sphagnum moss. All these form spongy peat which is stagnant.
Most of the water present in this wetland comes from rainfall instead of runoff or streams from the groundwater which makes it a wetland with a shallow area of water-saturated soil. This wetland is known for its less photosynthesis.

How was the earths biosphere affected during the Precambrian era
Answer:
Some three billion years ago, the Earth's atmosphere was virtually devoid of oxygen. At about 2.4 billion years ago, oxygen was released from the seas as a byproduct of photosynthesis by cyanobacteria. Levels of the gas gradually climbed, reaching about one percent around two billion years ago.

How does energy flow through a system?
Answer:
In general, energy flows from the Sun to producers and then to consumers. The path is linear as the energy present in one step is transferred to the next. You can find specific examples of this pathway in an ecosystem. ... Energy may be lost in living systems as it flows through them

what is the difference between phenotypes and genotypes
Answer:
Phenotype are physical traits a organism can inherit for example color, height, or body features are phenotype. Genotype are genetic traits that can be inherited for example personality, or behavior traits. So the primary difference between phenotype and genotype is that "phenotype are psychical characteristics while genotype is genetic."

process represents cellular division in body cells?
Answer:
There are two types of cell division: mitosis and meiosis. Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a fundamental process for life.

Answer:
Increasing carbon dioxide concentration increases the rate of photosynthesis as carbon dioxide (CO2) is a limiting factor.
Explanation:
Some limiting factors like carbon dioxide, temperature etc. influence the photosynthetic rate, which may end up reducing the potential amount of carbohydrate produced by photosynthesis. Carbon dioxide is important for this form of biosynthesis: it provides the inorganic carbon that is integrated into carbohydrate molecules.
The photosynthetic rate can be slowed by a decline in the concentration of available carbon dioxide.
6 CO2 + 6 H2O + light → C6H12O6 + 6 O2
Carbon Dioxide + Water + Light Glucose + Oxygen

What is formed by organized groups of cells with similar structures and a common purpose?
A
organ
00
digestion
С
circulation
D
tissue
Answer:
Cells with similar structures and a common purpose that are organized form a tissue (option D).
Explanation:
Biological tissues are structures originated by the grouping of differentiated cells, which are organized and distributed in such a way that they can fulfill a function in a coordinated way. A characteristic of tissues is that all the cells that constitute them have the same embryonic origin.
An example of a tissue is nervous tissue, formed by neurons, specialized cells that when united form it and fulfill the same function.
The functions of cells are mainly multiplication, development and differentiation, in addition to their ability to group together to form tissues.
The other options are not correct because:
A. Organs are formed from differentiated tissue.
B and C. Digestion and circulation are functions that depend on the organs of the digestive and circulatory systems, respectively.

Q1. Of which wavelength of light do carotenoids absorb the greatest percentage?
a)400nm
b)500nm
c)600nm
d)700nm
Answer:
B. it's between 460 and 550 nm which would put 500 almost directly in the middle
Explanation:
The wavelength of light which carotenoids absorb the greatest percentage is:
B)500nmA wavelength of light is the visible light which the human eye can see. These have different wavelengths of which some are longer than the others, such as the infrared and the ultraviolet rays
A carotenoid is a type of pigment which are yellowish, orange and red and occurs in plants and algae.
As a result of this, we can see that a wavelength of light which carotenoids absorb the greatest percentage is anywhere between 460-550 nM which would fall under the range of option B
Therefore, the correct answer is option B

mRNA:
Answer:
In the transcription of DNA to mRNA, for the DNA sequence 3'-AGGTCTCAC-5' corresponds to an mRNA sequence 5'-UCCAGAAGUG-3'.
Explanation:
Transcription is the process by which a strand of mRNA, needed to direct protein synthesis in the cytoplasm, is synthesized from a strand of DNA.
The sequence of nucleotides in the RNA chain depends on the sequence of bases in the DNA strand, being placed according to the complementarity of nitrogenous bases, where a purine is complemented with a pyrimidine.
In RNA, the thymine base is replaced by Uracil, the complementary base to adenine of DNA.

What do you mean by amino acids?Amino acids are organic compounds that contain both amino and carboxylic acid functional groups. Although hundreds of amino acids exist in nature, by far the most important are the alpha-amino acids, which comprise proteins. Only 22 alpha amino acids appear in the genetic code.
Moreover, amino acids are molecules that combine to form proteins. Amino acids and proteins are the building blocks of life. When proteins are digested or broken down, amino acids are left. The human body uses amino acids to make proteins to help the body: Break down food.
Therefore, these 12 amino acids are isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, valine, cysteine, tyrosine, histidine and arginine.
