Answer:
Melanoma is a type of skin cancer that develops in certain skin cells called melanocytes. These are the cells that make the pigment (melanin) that colors your skin. When exposed to UV radiation, such as sunlight, the melanocytes make more pigment, causing the skin to darken or tan. Melanoma starts in cells in the skin called melanocytes. These cells are in the deep layer of the epidermis between the layer of basal cells.
Jaundice causes the skin and the whites of the eyes to turn yellow. The higher the bilirubin level, the yellower the skin. Severe jaundice usually also causes itching and bile. Bile is fluid secreted by the liver.
How can you determine if a bacterium is being killed by an antibiotic or if its growth is simply being inhibited
Answer:

If a true-breeding tall pea plant is crossed with a true-breeding dwarf pea plant and all of the offspring are tall plants, the trait tall plant is:
Answer:
It is dominant over "dwarf plant."
Explanation:
If a true-breeding tall pea plant is crossed with a true-breeding dwarf pea plant and all of the offspring are tall plants, the trait tall plant is it is dominant over "dwarf plant."
What is dominant traits?Dominant traits are always explained when the related allele has dominant, even if only one copy of the dominant trait exists. Recessive traits are expressed only if both the connected alleles are recessive.
The frequency of expression of dominant and recessive traits can be Dominant traits = always / Recessive = sometimes.
According to the question if there is self cross TT×tt then there is TT, Tt, Tt and tt, which means there is a 75% possibility of dominant trait and 25% recessive.
A dominant trait has an inherited trait or characteristic that appears in an offspring and covers the effects of another allele and/or prevails or exhibit its trait above another.
Therefore, If a true-breeding tall pea plant is crossed with a true-breeding dwarf pea plant and all of the offspring are tall plants, the trait tall plant is it is dominant over "dwarf plant."

How has the average temperature on Earth changed over time?
Earth's temperature has risen by 0.14° F (0.08° C) per decade since 1880, and the rate of warming over the past 40 years is more than twice that: 0.32° F (0.18° C) per decade since 1981. ... From 1900 to 1980 a new temperature record was set on average every 13.5 years; from 1981–2019, a new record was set every 3 years.

1. Will loves to go fishing in the coastal estuary. He brings home his catch every weekend and bakes the fish for dinner. The next time he goes to his favorite fishing area, a sign is in place, warning residents of high heavy metals in the water. Which statement best explains the impact of eating fish from the estuary?
Heavy metals can biomagnify in large fish, making human consumers ill.
Heavy metals are water soluble; humans can eat them in small amounts.
Large fish will die from the heavy metals, but small fish can be consumed.
Will should avoid small fish but can collect large fish with less heavy metals.

One of the hottest ideas in engineering today is the concept of building an energy capturing system
similar to photosynthesis. The system would use light energy to make artificial food. What two
parts would such a system need, and how must these parts interact if they are to be like
photosynthesis?
The capturing device and converter are the two parts needed by the energy capturing system in order to make food.
If an energy capturing system wants to perform the same function of photosynthesis, then it must have two parts i.e. converter and capturing device. The capturing device works to capture or absorb light energy and send it to the place where this energy energy is converted into food.
The second part is the converted which convert light energy into food particles. These two parts interact with each other then the desire product will e achieved otherwise not so we can conclude that capturing device and converter are the two parts needed by the energy capturing system in order to make food.

If the alleles of two different genes are present on the same chromosome, the closer they are to each other the more likely they are to ________________________________ during gamete production.
If two alleles of different genes are in close proximity with each other on the
same chromosome, they would most likely link during gamete production.
Meiosis is the type of cell division that takes place in gamete( sperm and egg cells) production. The alleles are responsible for the phenotype of an
organism.
When alleles are in close contact on the same chromosome they are most
likely to be linked together and transmitted as a single unit . These brings
about variation between parents and daughter cells in some features such
as color, height etc

How do the properties of lipids
help explain the structure of a cell membrane?
Explanation:
Lipids give cells membranes a flexible structure which forms a strong barrier between the cell and its surroundings
Answer:
Lipids give cells membranes a flexible structure which forms a strong barrier between the cell and its surroundings. This tells us that the lipid surrounds the structure which then forms the shape of the cell.
Explanation:
The release of one phosphate group from ATP powers the reactants in the cell which phosphate is the one that is released from ATP
Answer:
ADP
Explanation:
Your question: The release of one phosphate group from ATP powers the reactants in the cell which phosphate is the one that is released from ATP
My answer: ADP
Why is my answer correct?
If a cell needs to spend energy to accomplish a task, the ATP molecule splits off one of its three phosphates, becoming ADP (Adenosine di-phosphate) + phosphate. The energy holding that phosphate molecule is now released and available to do work for the cell.

glial cells that surround the neurons in ganglia are:
Answer:
Explanation:
Satellite cells are small glia that surround neurons' sensory ganglia in the ANS. These resemble the astrocytes of the CNS and assist in regulating the external chemical environment. PNS satellite glia are very sensitive to injury and may exacerbate pathological pain.
Glial cells surrounding the neurons of neurons are satellite cells.
What are the functions of glial cells?Glial cells are a type of cell that provide physical and chemical support to neurons and maintain their environment. Located in the central nervous system and peripheral nervous system.
Glial cells outnumber neurons in the brain and outnumber them by a ratio of 3:1. Although glial cells also have complex processes extending from their cell bodies, they are generally smaller than neurons and lack axons and dendrites.
Oligodendrocytes form the myelin sheath around axons. Astrocytes supply neurons with nutrients, maintain their extracellular environment and provide structural support. Microglia clear pathogens and dead cells.
