Answer:
D
Explanation:
plant cells are the only kind of cell to have cell walls
The statement 'plant cells are surrounded by a cell wall, while animal cells are not' correctly describes the difference between plant cells and animal cells (Option D).
Both plants and animals are eukaryotic organisms, which means that their cells have nuclei and contain membrane-bound organelles.Plant cells contain an organelle known as chloroplast, which is used by these organisms during photosynthesis. Moreover, the plasma membrane of plant cells is surrounded by a cell wall that provides structural support to their cells.In conclusion, the statement 'plant cells are surrounded by a cell wall, while animal cells are not' correctly describes the difference between plant cells and animal cells (Option D).

gamete cells :)
Explanation:
hope this helps
Haploid cells are produced during meiosis.
Identical haploid daughter cells are produced from diploid parent cell.This process is required to produce egg and sperm cells for s exual reproduction.What is meiosis?Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for s exual reproduction.Cell division occurs twice during meiosis, one starting cell can produce four gametes.In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase.To know more about meiosis here

Digestion and breathing are _____. controlled by ganglia and plexus reflexive actions controlled by the spinal cord voluntary actions controlled by the central nervous sytem
Answer:
The correct answer is - reflexive actions controlled by the spinal cord.
Explanation:
Digestion and breathing are examples of involuntary action which is controlled by the autonomic nervous system of the CNS. however, the part of the nervous system that controls is the spinal cord and hind brain by the spinal reflex actions.
These are the action they do not require any thought and work without any thought that leaves the brain for other actions and coordinations. specific but the same stimuli causes the response in the same way.
what cause asexual reproduction
Answer:
It is a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes.
The offspring that are produced by asexual reproduction from a single cell or from a multicellular organism inherit the genes of that parent and thus have the sane identical identities of the parent.

How does weathering affect Earth's surface?
Answer:
Weathering can wear away any exposed surface on earth over time. It can cause rough surfaces to become smooth, much like a tumbler smooths a rock. An obvious example of weathering is the change of the landscape at the sea. The tides can cause the beach to become smaller or larger.
Explanation:
Answer:
Weathering is the breaking down or dissolving of rocks and minerals on Earths surface.
Explanation:
Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. ... Weathering and erosion constantly change the rocky landscape of Earth. Weathering wears away exposed surfaces over time.

(e) Describe the role a non-competitive inhibitor would play in the ability of enolase to perform
properly.
Answer:
it would not allow enolase to perform properly because it will bind to it and change its shape not allowing 2-phosphoglycerate to bind to it and convert to phosphoenolpyruvate. this is because it is non-competitive which means there is no way that the molecule could bind to the enzyme.

Which of the following questions would BEST
determine whether a plant is undergoing the
Calvin cycle?
A. Is NADPH being produced?
B. Is oxygen being produced?
C. Is glucose being produced?
D. Is ATP being produced?
Answer:
C
Explanation:
Glucose is the end result of the calvin cycle. It is not Oxygen, NADPH, or ATP because those are produced in the light reactions.
Is glucose being produced? is the question which will best determine
whether a plant is undergoing the Calvin cycle.
The Calvin cycle is known s the light independent or dark reaction which
takes place during the process of photosynthesis by plants. The final
product for this cycle is Glucose.
Other compounds such as NADPH, ATP and oxygen are all formed during
the light dependent reactions which is why asking if glucose is produced is
the most appropriate choice.

An individual is heterozygous for a gene at a specific locus. ________ will have the same form of alleles at that locus after S phase.A. Sex chromosomes.B. Homologous chromosomes.C. Non-sister chromatids.D. Sister chromatids.
Answer:
D
Explanation:
Sister chromatids will have the same form of alleles at the locus after S phase.
This is because during the S phae of the cell cycle, sister chromatids are replicated in preparation for cell division. The replication process is quite accurate such that all the alleles present on the initial chromatids are also replicated on the new sister chromatids. Hence, both new and old chromatids will have the same form of alleles at the locus after replication at the S phase. In other words, sister chromatids are exact copy of one another.
The correct option is D.

Draw a flow chart that explains how DNA is used to create an organism. please use the words: DNA, gene, protein, cell, tissue, organ, organism.
Answer:
Please find the flowchart attached as an image
Explanation:
DNA is the genetic material contained in the cells of living organisms. The DNA contains a segment called GENE, which contains information used to produce useful products needed in the cell. The information contained in the gene is expressed to produce PROTEINS.
PROTEINS are responsible for many metabolic activities that occurs in a cell. The CELL functions due to activities of the proteins produced by gene expression. When similar cells come together, they form TISSUES. An aggregation of tissues performing similar functions form ORGAN. Organs functioning similarly come together to form ORGAN SYSTEM. A collection of organ systems in the body forms the ORGANISM.
