Which is required for sexual reproduction
Answer:
meiosis
Explanation:
meiosis is used to produce gametes for sexual reproduction
Answer:
Meiosis, and female and male
Explanation:
Sexual reproduction is a reproduction that requires a male and a female of the same species to contribute genetic material. Special cells called gametes are produced through meiosis, which halves the number of chromosomes in each resulting cell. These cells are called haploid gametes.
Which best describes the importance of meiosis to living organisms? *
O genetic variation and growth
O growth and development
O development and sexual reproduction
O sexual reproduction and genetic variation
lee and Celia are lab partners. While Celia pours a chemical into a graduated cylinder, some of the chemical splashed onto her arm . What should happen next?
Answer:
Celia should tell the teacher and wash her hands and arms twice.
Explanation:
She should tell the teacher because if she is unsure of what to do, the teacher can help her. If there is no teacher present, she should wash her hands and arms twice to remove as much of the chemical as possible. Then she should call a poison help or chemical help center if she is unsure of what to do next.

What is the energy source that allows photosynthesis to occur?
Answer:
[tex]\boxed {\boxed {\sf The \ sun }}[/tex]
Explanation:
Photosynthesis is a special process that certain organisms (plants, algae, and some bacteria) undergo to create "food".
This turns light energy, carbon dioxide, and water into glucose and oxygen. The glucose becomes the food for the organism, because it is turned into ATP during cellular respiration. The ATP is energy that fuels the processes, like growth, repair, and transport.
This process occurs because of the sun. It provides the light energy needed for the reaction. Organelles inside of the cells, called chloroplasts, contain a pigment (chlorophyll) that captures this energy.
The image below shows plant cells.
What feature of cells is best demonstrated in the image?
OA Cells are the basic units of structure and make up tissues.
OB. All organisms are made up of a large number of cells.
OC. All organisms have cells with different shapes and functions.
OD. Cells are formed from other cells within the same tissue.

All living organisms store genetic information that can be passed on from parent to offspring. How does the biomolecule responsible for storing this information differ from other biomolecules?
Answer:B
Explanation:
A _______________ from the sun hits chlorophyll and excites an electron, known as __________________________________.
Answer:
Photon, light dependent reaction of photosynthesis
Explanation:
Photosynthesis is the process by which green plants make their own food in the presence of sunlight and water.
There are two steps of Photosynthesis that include light dependent reaction and light-independent reaction.
In light dependent reaction, a photon from the sun is absorbed by the green pigment in leaves called chlorophyll that allow the electron to excite from ground energy level to high energy level. It converts the solar energy into chemical energy and called light dependent reaction of photosynthesis.
Hence, the correct answer is "Photon, light dependent reaction of photosynthesis".

Two offspring from same parents can have different phenotypes. How is this possible?
Answer:
Genes come in different varieties, called alleles. Somatic cells contain two alleles for every gene, with one allele provided by each parent of an organism. However, an allele that is hidden, or not expressed by an organism, can still be passed on to that organism's offspring and expressed in a later generation.
Explanation:
Overdominance, in instance, happens when a heterozygote exhibits a more extreme phenotype than either of its parents.
What is heterozygote?Heterozygote is defined as a person, animal, or other thing possessing a pair of different alleles of a specific gene, one of which is dominant and the other recessive. One normal allele and one mutated allele, or two distinct mutated alleles, can make up a heterozygous genotype.
The explanation is connected to the fact that each parent has two different gene pools. Furthermore, only 50 percent of each parent's DNA is transferred to their offspring. and that the portion that is passed down is random. Every child has a unique set of genes thanks to the interaction of all these influences.
Thus, overdominance, in instance, happens when a heterozygote exhibits a more extreme phenotype than either of its parents.

The table below shows the initial and final masses of a radioactive material whose half-life is 15 years.
Initial mass (in kilograms): 0.8
Final mass (in kilograms): 0.05
Based on the table, which of these conclusions is correct?
A.) The material decayed from 0.8 kilograms to 0.05 kilogram in 60 years.
B.) The material decayed from 0.8 kilograms to 0.05 kilogram in 30 years.
C.)The mass of the material was 0.1 kilograms after four half lives.
D.) The mass of the material was 0.1 kilograms after five half lives.
Answer:
A
Explanation:
1 half-life = .4 kg = 15 years
2 half-life = .2 kg = 30 years
3 half-life = .1 kg = 45 years
4 half-life = .05 kg = 60 years
Answer:
A
Explanation:
Initial mass is 8. The half-life is 15 years.
1st half life=.8/2=.4
2nd half life=.4/2=.2
3rd half life=.2/2=.1
4th half life=.1/2=.05
For each half life that it took it to go from .8 to 0.05, you add 15 years since that is the half life of the substance. 4*15=60.
So, the answer is A. The material decayed from 0.8 kilograms to 0.05 kilogram in 60 years.

What are the locations and end products for the processes of transcription and
translation?
The cytoplasm is the site of translation, the next process that converts a gene into a protein. In order to “read” the sequence of mRNA nucleotides, the ribosome, a specialized complex, interacts with the messenger RNA.
What is role of gene expression in an organism?It serves as both a volume control that raises or lowers the level of proteins produced, and an on/off switch to regulate when proteins are created.
Because a particular protein can only be made when its gene is turned on, gene expression is significant.
But the process of turning a gene into a protein involves numerous steps, and one of these phases—the production of proteins—is essential for the gene expression pathway that can be altered in cancer.
Therefore, transcription occur at nucleus and translation take place in cytoplasm.

Fossil remains of Glossopteris (an extinct plant with large leaves) have been discovered in India and Australia. When they were living, all the Glossopteris were located together on land, but now the Glossopteris fossils are separated by an ocean. What could explain how these fossils got so far apart?
Answer:
Due to splitting of lands.
Explanation:
These Glossopteris fossils got so far apart from each other because of the splitting of super continent about 175 million years ago. Before 175 million years, India and Australia are attached to each other and these Glossopteris plants are present on these lands but with the passage of time, the lands of India and Australia split and go far away from each other so due to splitting of lands, these fossils got so far apart from each other.

A student states that petrification occurs when pore spaces in an organism's remains are filled with minerals that precipitate out of solution. What is wrong with this statement?
A.
Permineralization occurs when pore spaces in an organism's remains are filled with minerals that precipitate out of solution.
B.
Petrification occurs when once-living tissues are replaced by minerals, preserving the organism's structure.
C.
Both A and B describe errors in the statement.
D.
Nothing, this statement is correct as is.
Answer:
C. Both A and B describe errors in the statement.
Explanation:
In fossilization i.e formation of fossils, two terms are used as follows: permineralization and petrification.
- Permineralization is a process whereby the pore spaces of an organism's remains are filled with mineral matter that precipitates from lake and ocean solutions.
- On the contrary, petrifaction or petrification is the process whereby a once-living tissue (matter) are REPLACED by minerals, hence, preserving the organism's structure by turning it into a stone (petros).
According to this question, the student mixed up their definitions by giving the definition of permineralization instead, however, options A and B have described the errors associated with the statement.
