Answer:
An adaptation is a characteristic that helps living things survive and reproduce in a given environment. It comes about because living things have the ability to change over time in response to the environment
Explanation:
Sensory neurons are considered to be efferent neurons because they take information from organs to the brain and the spinal cord.
a. True
b. False
True or false. Some genetic variations arise from mutations, which are changes in the hereditary material.
Answer:
True.
Explanation:
These genetic variations and mutations are hereditary.
They need to be hereditary to be inherited to the offspring since these changes are genetic.
These changes are in the hereditary material.
Hope this is correct, have a great day.
Over time, three types of cells derived from this single-celled animal have emerged with specialized functions and they interact as a multicellular organism.
Type 1: Launches the toxin-loaded vesicles. Non-motile
Type 2: Detects the toxin, moves, and hunts the prey.
Type 3: Engulfs the bacteria, breaks them down, and stores the parts. Non-motile
Required:
What organelles do each type have?
Answer:
Golgi bodies, endoplasmic reticulum and lysosomes.
Explanation:
Many vesicles are formed in the Golgi bodies and the endoplasmic reticulum, that is responsible for the transportation of materials from one part of the cell to another. Endoplasmic reticulum is the organelle that launches the toxin-loaded vesicles or in other words it is responsible for detoxification i. e. removal of toxic substances from the cell. Lysosomes is the organelle that act against the microorganisms such as bacteria , virus etc.

Explanation:
The following genotypes of two independently assorting autosomal genes determine coat color in rats:
A—B—(gray); A—bb (yellow); aaB—(black); aabb (cream)
A third gene pair on a separate autosome determines whether or not any color will be produced. The CC and Cc genotypes allow color according to the expression of the A and B alleles. However, the cc genotype results in albino rats regardless of the A and B alleles present. Determine the F1 phenotypic ratio of the following crosses:
a. AAbbCC x aaBBcc
b. AaBBcc x AABbcc
c. AaBbCc x AaBbcc.
Answer:
a) 100% Gray
b) 100% albino

How does extinction affect evolution?
It speeds up the evolution of other species.
o it slows down the evolution of other species.
O it completely stops the evolution of a species.
It has no effect on evolution.
Answer:
It completely stops the evolution of a species
Explanation:
Because if the species does not continue to live their will be no growth or develop so it cant evolve.
Answer:
It completely stops the evolution of a species
Explanation:
What is the velocity of a car traveling north, 100 meters in 25 seconds? Explain how you got that answer
Answer:
4 meters/second (4 m/s)
Explanation:
velocity=distance/time
distance= 100 meters
time= 25 seconds
v=100m/25sec = 4 meters/second (4 m/s)
How do changes in the environment affect an ecosystem ?
(5-7 sentences)
Answer:
There are many ways the environment changes an ecosystem. First, temperature can completely affect an ecosystem. This is important because if an ecosystem gets too warm or cold, the organisms living in there can die off since they aren't made to live in severe conditions. Secondly, weather can also affect an ecosystem by raining, wind, or natural disasters. This is important to an ecosystem because if it rains too much in an ecosystem that needs to stay dry, than the organisms could die. Finally, migration could also affect an ecosystem. Even though this seems odd, it surprisingly changes a whole ecosystem. If predators migrate to the ecosystem, than the organisms are at risk because they are prey and could be eaten. Clearly, an ecosystem can be affected by many things.

Answer:
Cells make up tissues, tissues make up organs, and organs make up organ systems. The function of an organ system depends on the integrated activity of its organs. For instance, digestive system organs cooperate to process food.
Explanation:
Answer:
Cells make up tissues, tissues make up organs, and organs make up organ systems.
Explanation:
The cell is a fundamental component of all organisms. A group of cells that have the same structure and function make up a tissue. There are four types of tissues in our body: muscular, connective, nerve, and epithelial. Several types of tissue connect into an organ. The organs collectivley make an organ system. The 12 systems in the body are nervous, digestive, cardiovascular, muscular, skeletal, endocrine, urinary, immune, integumentary, respiratory, excretory, and reproductive.
