Which of the following processes involves the chloroplast?a. cell divisionb. conversion of light energy to chemical energyc. formation of reproductive cells d. stringing amino acids together
Answer:
[tex]\boxed{\tt B. \ Conversion\ of\ light \ energy \ to \ chemical \ energy}[/tex]
Explanation:
This question asks us which process involves the chloroplast.
In plants, algae, and some bacteria, a process called photosynthesis occurs. This process takes place in the chloroplasts. In the process, the organism takes light energy from the sun, carbon dioxide, and water, and turns it into glucose and oxygen.
The glucose that is made becomes the food and energy for the organism. In another process, called cellular respiration, the sugar is turned into ATP, a kind of useable energy.
The best answer choice is B. Conversion of light energy to chemical energy. The chloroplasts convert light energy to sugar, and the sugar becomes chemical energy.

Humans autosomal cells have two copies each of 23 unique chromosomes. Match each cell division event and cell type according to the number of chromatids present.
Answer:
Mitosis cell division--- 46 chromosomes.
Meiosis cell division--- 23 chromosomes.
Explanation:
If the cell division occurs and the daughter cells formed with 46 number of chromosomes each so this is mitosis cell division because both the daughter cells receives double number of chromosome whereas, if the cell division happens and the daughter cells formed with 23 number of chromosomes each so this is meiosis cell division because all the daughter cells receives half number of chromosome.

Which two characteristics do all animals have?
Answer:
All animals are eukaryotic, multicellular organisms, and most animals have complex tissue structure with differentiated and specialized tissue. Animals are heterotrophs; they must consume living or dead organisms since they cannot synthesize their own food and can be carnivores, herbivores, omnivores, or parasites.
Explanation:
The two characteristics that all animals have in common is that their cells have a nucleus and membrane-bound organelles. The correct option is C.
What are eukaryotic organisms?Eukaryotes are organisms whose cells have membrane-bound organelles in addition to a nucleus.
Eukaryotic creatures come in a great variety, including most algae, all animals, plants, fungus, and protists.
Prokaryotes are creatures without a nucleus or other organelles in their cells. Bacteria and archaea, two separate groupings of prokaryotes with allegedly independent evolutionary histories, are separated into.
The majority of prokaryotes are tiny, single-celled creatures with a straightforward structure.
Each animal has a cell that is composed of different organelles, including the nucleus, which houses all of the essential information, including DNA, and a membrane-bound organelle that protects and molds the cell.
As a result, the nucleus and membrane-bound organelles are among animals' shared traits.
Thus, the correct option is C.

Answer:
The four main categories of large biological molecules present in living systems are proteins, nucleic acids, carbohydrates and lipids.
Explanation:
Biological molecules (bio-molecules) are the building blocks of a the cell.
The four main categories of large biological molecules present in living systems are proteins, nucleic acids, carbohydrates and lipids.
Proteins are large biological molecules composed of smaller molecules called amino acids. Proteins are required for many important functions in the cell such as cell structure, metabolism and growth.
Nucleic acids are important biological molecules that contain the information required for the continuity of life.
Carbohydrates are essentially required for nutrition and growth. They also serve structural purposes as well as many other functions.
Lipids are divided into fats and oils. They serve various functions such as energy stores, and also provide insulation to the living organism.

Which biogeochemical cycle does NOT involve a
stage where the chemical enters the atmosphere?
a. water cycle
b. carbon cycle
c. nitrogen cycle
d. phosphorus cycle
Answer: D. phosphorus cycle
Biogeochemical cycles include the transfer of nutrients and other essential elements among biotic and abiotic factors. The correct answer is option d i.e. phosphorus cycle.
Phosphorus cycle is a sedimentary cycle, which does not have any gaseous component. It does not involve any stage where the chemical enters the atmosphere. Phosphorus travels through the hydrosphere, lithosphere, and biosphere during this biogeochemical cycle. The weathering of rocks releases phosphorus. Phosphorus is removed from the soil and water bodies by rain and erosion. Animals and plants get this phosphorus from the soil and water in order to flourish. Phosphorus is also necessary for the development of microorganisms. When plants and animals perish, they decompose, returning the stored phosphorus to the soil and water bodies where it is once more ingested by new plants and animals, continuing the cycle.
Therefore, the correct answer is phosphorus cycle, i.e. option d.

a unit made of different kinds of elements
a unit made of only one kind of element
a unit made of two or more atoms
a unit made of a single atom
Of the mentioned options, the statement that best describes a molecule is that it is a unit made of two or more atoms.
What is a molecule?It is the smallest particle in a chemical compound or element, which possesses similar properties with that of the compound or element. The molecules are formed of atoms, which are held together with the help of chemical bonds.
These bonds develop as an outcome of the exchange or sharing of electrons between the atoms. The atoms of elements bond easily with other atoms to produce molecules. The molecules can differ largely in complexity and size.

water
gravity
space
Answer: Gravity every other option we need for life
Explanation:
Every other option we need for life, otherwise we would not be alive.
The one that is not needed by living organisms is gravity. The correct option is D.
What is gravity?An invisible force that attracts objects to each other Gravity is what keeps you on the ground and causes things to fall.
Universal Gravity is a theory about the natural law of attraction, not a fact. This material should be approached with an open mind, carefully studied, and critically analyzed.
Nonliving things are required for the survival of living things. Living things die in the absence of food, water, and air.
Sunlight, shelter, and soil are also essential for life. Living things in ecosystems get their food from both living and nonliving things.
Every living thing needs food, water, shelter, and a place to live. Its habitat is the location where it obtains these items.
Thus, the correct option is D.
