Explanation:
In cells where there is a high energy demand large numbers of mitochondria are found. The tail of a sperm contains many mitochondria and they run in a spiral like form along the length of the tail. In heart muscle cells about 40% of the cytoplasmic space is taken up by mitochondria.
Which organisms synthesize carbohydrates, and in which cell organelle(s) does this synthesis occur?
a. animals in mitochondria
b. plants in mitochondria
c. plants in chloroplasts
d. animals and plants in mitochondria
e. animals and plants at ribosomes
Answer:
C
Explanation:
Green Plants are the main producers of starch as carbohydrate.In order to carry out this special organelle Chloroplast are specially adapted for this purpose,
Green plant are made up of Chlorophyll which are the green pigments that for trapping sunlight for the synthesis of starch to occur.
Photosynthesis is the process of synthesis of the starch.It involves the reaction of C02 with water in the presence of sunlight and enzymes to give oxygen as the byproduct, and Starch( carbohydrate) as the main product.
This process occur in two pathways the light dependent pathways and the light independent pathways,
Green plant and some organisms phytoplankons,algea are capable of producing starch through photosynthesis because of the green pigment they possess.Therefore they are said to be Autothrophic.

If 10 cells undergo the cellular process of meiosis, how many daughter cells will result after Telophase II?
a. 25
b. 5
c. 10
d. 40
Which of the following completes the sentence below by describing an important result of meiosis?
A single cell divides into ___________ daughter cells.
2 identical
2 unique
4 unique
4 identical
A.4 identical
B.4 unique
C. 2 unique
D. 2 identical
Answer:
d. 40, B.4 unique
Explanation:
If 10 cells underwent meiosis, the result would be 40 daughter cells. This is because a cell that goes through meiosis goes through two divisions resulting in 4 daughter cells. This is because cells that undergo meiosis are gametes so they need to have half the number of chromosomes as the cells that go through mitosis.
The resulting daughter cells are unique, unlike the cells that go through mitosis. This is because the chromosomes in the cells experience something called crossing over during Metaphase I. Crossing over is when the chromosomes can swap pieces of DNA when next to each other. Cells in mitosis don't go through crossing over and are therefore identical.

The Marianas trench contains Challenger Deep, the deepest point in the ocean floor that we know of today. Challenger Deep is located over 11,000 meters below the ocean surface. What ocean zone would be located just above the floor of Challenger Deep?
Answer:
Above the floor of challenger deep, the ocean zone located would be the Hadal zone .
Explanation:-
THE CHALLENGER DEEP - The deepest location in the ocean is the Challenger Deep, at the southern end of the Mariana Trench (sometimes called the Marianas Trench). It is difficult to measure its depth from the surface, but modern estimates vary from 305 meters (less than 1,000 feet). The Challenger Deep 's great depth is due to the successful steepening of the subducting slab along a region of poor link with the overriding plate tearing away from the northern part of the Mariana Trench in the southern part of the Mariana Trench.
THE HADAL ZONE -: The Hadal zone (named in Greek mythology after the domain of Hades, the underworld),, is the ocean's deepest area lying within oceanic trenches. The hadal zone is located at a depth of about 6,000 to 11,000 meters (20,000 to 36,000 feet) and is present in long but narrow V-shaped topographic depressions.
Hence, the answer is Hadal zone ,which is located just above the floor of Challenger Deep.
Answer:
Hadal zone
Explanation:
I took the test and Hadal zone was the correct answer for this question
In a changing environment, which species will have the best chance for survival? Group of answer choices The ones that are super fast. The one with the largest population. The one with the biggest genetic variation. The one with the most intelligent individuals
Answer:
one with the largest poplation because they can cook,protect, and get supplies .
Explanation:
In a changing environment, the species which will have the best chances for survival are the one with the biggest genetic variation. Thus, the correct option is C.
What is Genetic variation?Genetic variation is the difference in DNA present among different individuals or the differences between the populations. The multiple sources of genetic variation include mutations and genetic recombination in species. Mutations are the ultimate source of genetic variation, however other mechanisms, such as genetic drift, contribute to it, as well.
Variation allows some individuals within a population to adapt better to the changing environmental conditions. Because, the natural selection acts directly only on phenotypes, more genetic variation within a population usually enables more phenotypic variation in a population.
Therefore, the correct option is C.

What are sources of nitrogen in the environment ?
Answer:
Atmospheric precipitation, livestock and poultry operations and urban wastes.
Explanation:
A molecule has been isolated from a cell. The molecule's structure has a three dimensional shape and is made of folded chains of amino acids. The function of this molecule is enzymatic catalysis of glycolysis. An analysis of this molecule would show that it contains which of these elements that would NOT be found in carbohydrates
Answer:
Nitrogen.
Explanation:
Although the options for this question is not available,the major food molecules of Carbohydrate,Protein ,and Lipids all contain the elements C,H,O.
However,Nitrogen is the only elements that is present in Protein,but absent in the other food molecules.Consequently,Nitrogen is answer.
The Nitrogen forms the Amine-NH2 - of protein.
The fact that the molecular structure has a 3-D shape,with folded chains of amino acids,it show that it is protein of tertiary structure.Although enzymes are globular proteins but of tertiary structure.
Tertiary proteins are 3-D and the R-groups interacts with each other for distinct chemical structure

About how long ago did our solar system start to form?
O About 5 million years ago
O About 14 million years ago
O About 5 billion years ago
About 14 billion years ago
Answer:
about 5 billion years ago
Explanation:
Our solar system formed about 5 billion years a go from a dense cloud of interstellar gas and dust.
Our solar system started to form approximately 5 billion years ago. Option 3 is correct.
This estimation is based on scientific evidence and observations of the formation and age of celestial bodies in the universe. The formation of our solar system is believed to have been initiated by the gravitational collapse of a giant molecular cloud composed of gas and dust. As the cloud collapsed under its own gravity, it began to spin and flatten into a rotating disk-shaped structure known as the protoplanetary disk. The central region of this disk eventually formed the Sun, while the surrounding material coalesced to form planets, moons, asteroids, and comets.
The age of our solar system is determined through radiometric dating techniques, which involve measuring the ratios of radioactive isotopes in rocks and meteorites. These measurements, combined with other astronomical observations and models, provide a reliable estimate of the age of the solar system. The current scientific consensus is that the solar system formed approximately 4.6 billion years ago, placing its origin in the early stages of the universe's development. This understanding of the solar system's age is crucial for studying its evolution, understanding the formation of planets, and exploring the conditions necessary for the existence of life.
