Answer:
Nervous system messages travel through neurons as electrical signals.
Explanation:
When these signals reach the end of a neuron, they stimulate the release of chemicals called neurotransmitters. Neurotransmitters travel across synapses, spaces between neurons or between neurons and other body tissues and cells.

Explanation:
A can of antifreeze spills near a clump of Dryopteris dilatata, a type of fern. The chemical seeps into the ground, endangering the plant's roots. The plant roots grow as far away from the chemical as possible to absorb only fresh water and minerals.
During this process, the roots primarily work in conjunction with which system? a) The immune system to defend against the toxic chemicals
b) The vascular system to reduce the absorption and transport of toxic chemicals
c) The reproductive system to make more root cells
d) The digestive system to create enzymes that break down the toxic chemicals
Answer:D
Explanation:
I got it right on my test
Dryopteris dilatata is in family Dryopteridaceae. The movement of plant away from spill the roots primarily work in conjunction with vascular system to reduce the absorption and transport of toxic chemicals.
What is Dryopteris dilatata?Dryopteris dilatata is a fern mainly located in deciduous or semi-evergreen family, native of Europe.
It can be grown in most cool, moist and light shaded areas. It is also called as broad buckler-fern.
As to avoid antifreeze spills, the plant roots grow far away from the area of spill. During this process roots primarily work with vascular system to reduce absorption and transport of toxic chemicals.
Thus, the correct option is b.

Which is an example of genetic diversity? PLS HELP temperate rain forest and a tropical rain forest bees, jack rabbits, diamondback rattlesnakes bacteria, garter snakes, tigers variations in a flock of starlings
Answer:
temperate rain forest and a tropical rain forest bees.
Explanation:
The temperate rain forest and a tropical rain forest bees is the example of genetic diversity because the same organisms has different features which allows them to live in different climatic conditions due to their variation in genetics. The environment of temperate rain forest is different from tropical rain forest so the bees specie that live in both environment are different from one another in their genetic makeup and which is an example of genetic diversity.
3. What is the scientific term for a group of interacting individuals of the same type, living in the same area at the same time?
Answer: The scientific name is called POPULATION.
Explanation:
In basic ecological studies, POPULATION is defined as a group of interacting individual of the same type or species, living in the same area or habitat and at the same time.
Furthermore, to study a population of organisms, the different characteristics seen include:
--> Population size: This is important as it affects the survival of a given species in a habitat. A small population may be easily wiped out by events such a fire but a large population stands a better chance of survival.
--> Population frequency: This is simply how often the species occurs at different sites in a habitat.
--> Population density: this is the average number of individuals of a species per unit area of the habitat.
--> Percentage cover: This is the area of ground occupied by a given species in its habitat.
--> Distribution: This is the way in which individuals of a particular population are arranged in a habitat. They may be clumped, evenly spaced or randomly spaced.

beak shape, camouflage, and webbed feet are all examples of which type of adaptation
Answer:
beak shape: used to help an animal eat food like tearing apart food or either cracking nuts.
Camouflage: the color or shape of an animals body helps it blend into its envierment.
weebbed feet: help animal's propel themselves through the water with ease. This can help the animal swim faster to
catch prey or escape a predator. Also, if an animal has to swim long distances,
webbed feet can help it save energy so it can swim farther.

how are adaptation and variation similar?
Answer:
Adaptations are physical or behavioral traits that make an organism better suited to its environment. Heritable variation comes from random mutations. Random mutations are the initial cause of new heritable traits. For example, a rabbit can't choose to have a different fur color.

To measure a population’s baseline genetic state, it must have _____________ to be in Hardy-Weinberg equilibrium.
A) Gene Flow
B) Random Mating
C) Selection
D) Mutations
Answer:
Random mating
hope it helps!
There are five basic Hardy-Weinberg assumptions: no mutation, random mating, no gene flow, infinite population size, and no selection. If the assumptions are not met for a gene, the population may evolve for that gene (the gene's allele frequencies may change).
To measure a population’s baseline genetic state, it must have random mating to be in Hardy-Weinberg equilibrium (Option B).
The Hardy-Weinberg principle state that the genetic variation in a population will remain constant across generations in the absence of different evolutionary forces.The Hardy-Weinberg assumptions include random mating, no mutation, no gene flow, infinite population size, and absence of selection.In consequence, random mating acts to prevent any change in the allele frequencies.In conclusion, to measure a population’s baseline genetic state, it must have random mating to be in Hardy-Weinberg equilibrium (Option B).

Whích statement is best supported by the diagram?
А.
Species T and Species U are related to species X
B. Species X evolved later than Species U but before Species s.
С.
Species T is the ancestor of Species S.
D
Species U and V evolved from Species S.
Answer:
4
Explanation:
The statement that is best supported by the image is that species T and species U are related to species X.
What is evolution?Is the gradual development of new forms of organisms from their ancestral forms.
In the image, X is the ancestor of T, U, V, and S. Thus T, U, V, and S are related by common ancestry.
Thus, it is correct to say that T and U are related to species X.
However, it is incorrect to say that X evolved later or species U and V evolved from S.

What is a scientific theory? The sentences above help to describe a scientific theory. One sentence is not quite
accurate though. Choose the sentence that needs to be modified and make the necessary modification so it may be
included in the description of a theory.
A)
D. A scientific theory has a simple basis: an experiment done to test a
hypothesis.
B)
C. Theories are descriptions, often mathematical descriptions of natural
phenomenon;
A. A scientific theory is based on a scientific investigation that supports a
hypothesis.
D)
B. When new information does not support a scientific theory, the theory
may be revised or sometimes rejected.
Answer:
Original sentence: When new information does not support a scientific theory, the theory may be revised or sometimes rejected.
New changed sentence: When the results of the experiment do not support a hypothesis, the hypothesis must be revised or rejected to state a new scientific theory.
Explanation:
The scientific theory is a conceptual framework used to explain facts or phenomena and to make predictions.
The theory is fundamental to science because it allows scientists to organize and understand observations.
The construction of a theory begins with a hypothesis. The scientist believes that a phenomenon occurs in a certain way, so he/she performs observations under the scientific method to prove that his/her hypothesis is valid or not valid. The systematization of the observations and the empirical data collected might derive from a scientific theory that explains the analyzed phenomenon.
A scientific theory is a knowledge that has been contrasted in several ways.
