Answer: Simple Diffusion Across the Cell (Plasma) Membrane: The structure of the lipid bilayer allows small, uncharged substances such as oxygen and carbon dioxide, and hydrophobic molecules such as lipids, to pass through the cell membrane, down their concentration gradient, by simple diffusion.
Explanation: Large molecules like glucose or carbohydrates use proteins to help move across cell membranes. Some of the membrane proteins have carbohydrate Chains attached to help cells in recognize each other and certain molecules

Explain whether or not you expect the chaparral biome to be sensitive to the loss of a single species.
NEED HELP ASAP PLEASE!!
Answer:
Explanation:
The chaparral biome has a large amount of biodiversity, which helps insulate an environment against the loss of a single species. Therefore, one would not expect the chaparral biome to be too sensitive to the loss of a single species.

Use chromosomes 11 and 17 to answer the following questions. Chromosome Map Chromosome 17 is made of over million base pairs. Approximately how many genes are found on chromosome 17? List the genetic disorders found on chromosome 17. What do you know about any of those disorders?
Answer:
Hello!
Chromosome 17 is made of over 80 million base pairs.
Approximately how many genes are found on chromosome 17? 1600
Explanation:
Chromosome 17 is made up of more than 80 million base pairs. Approximately, 1600 genes are found on chromosome 17. The genetic disorders found on chromosome 17 are as follows:
Breast cancer.Neurofibromatosis.DNA damage response in individuals.Scoliosis.Congenital heart anomalies. What are Chromosomes?Chromosomes may be defined as thin, thread-like structures that may appear in the nucleus of the cell during the process of cell division. These structures may contain DNA, RNA, histones, and non-histone proteins. Chromosomes may be discovered by E. Strasburger in 1875.
Human chromosome 17 is implicated in a wide range of human genetic diseases. It is home to genes involved in many genetic disorders that may affect the physiology of an individual. They are very severe to organisms.
Mosaic trisomy 17 is a rare chromosomal anomaly syndrome, with a highly variable clinical presentation, mostly characterized by growth delay, intellectual disability, body asymmetry with leg length differentiation, scoliosis, and congenital heart anomalies.

Knowing what you know about photosynthesis, explain how the process may reduce
global warming (caused by too much carbon dioxide in the atmosphere).
Through the pores called stomata in their leaves, plants take in carbon dioxide from the atmosphere that they use for photosynthesis. ... But when carbon dioxide levels increase, plants' stomata shrink, releasing less water into the air and reducing the cooling effect.

how does the nervous system help the excretory system maintain homeostasis?
Answer:
The nervous system maintains homeostasis by controlling and regulating the other parts of the body. A deviation from a normal set point acts as a stimulus to a receptor, which sends nerve impulses to a regulating center in the brain.
Explanation:
The nervous system keeps the body in a state of homeostasis by controlling and regulating excretory system.
What is Homeostasis?In a broad sense, homeostasis refers to a system's stability or balance. It's the body's endeavor to keep its internal environment consistent. Internal environment stability necessitates regular monitoring and modifications as conditions change. Homeostatic control refers to the balancing of physiological systems within the body.How does nervous system regulates homeostasis?Because the nervous system does not store nutrients, it must get them from the bloodstream on a regular basis. Any disruption in blood flow might result in brain injury or death.The nervous system keeps the body in a state of homeostasis by controlling and regulating the other organs. A variation from a regular set point stimulates a receptor, which transmits nerve impulses to a brain regulating area.learn more about homeostasis here:

The first line of defense involves which structure(s)?
OT-cells
O skin
O blood
OB-cells
Answer:
skin
Explanation:
The skin is vital for our general health and well-being. In addition to acting as the body's first line of defense against bacteria and viruses, healthy skin also maintains fluid balance and helps regulate body temperature. She is very sensitive, she recognizes the slightest touch as well as pain.
As an outer layer that we can see and touch, the epidermis protects us from toxins, bacteria, and fluid loss. It consists of 5 sublayers of keratinocyte cells. These cells, produced in the deepest inner, basal layer, migrate to the surface of the skin. As they do so, they mature and go through a series of changes.
