Adrenergic receptors Select one: a. can be activated by the release of epinephrine. b. have two structural forms - muscarinic and nicotinic. c. when activated stimulate skeletal muscles to contract. d. can be found in both the sympathetic and parasympathetic divisions. e. are activated by the release of acetylcholine.
Answer:
The correct answer is a. can be activated by the release of epinephrine.
Explanation:
Epinephrine is a hormone and neurotransmitter naturally secreted by the body through the adrenal glands, synthesized and stored in the adrenal medulla and released into the systemic circulation. Epinephrine is a non-selective adrenergic agonist, stimulating alpha1-, alpha2, beta1, and beta2-adrenergic receptors. The systemic actions of catecholamines are mediated by the binding of these compounds to plasma membrane receptors, of the GPCR type widely distributed throughout the body and known as adrenergic receptors, which are activated by the catecholamines adrenaline (epinephrine) and noradrenaline . These receptors cause different effects depending on the G protein subtypes to which they are associated and the signal transduction mechanism linked to the specific G protein.

Which of the following can cause evolution to occur? (Select all that apply)
Mutation
If organisms choose a mate for a specific reason
People moving into or out of an area
If the population shrinks
Answer:
MutationIf organisms choose a mate for a specific reasonPeople moving into or out of an areaIf the population shrinksExplanation:
These factors are the "forces of evolution." There are four such forces: mutation, gene flow, genetic drift, and natural selection.
These are the factors that can cause evolution to occur:
MutationIf organisms choose a mate for a specific reasonPeople moving into or out of an areaIf the population shrinksThe most important feature that permits a gene to act as a molecular clock is The most important feature that permits a gene to act as a molecular clock is having a reliable average rate of mutation. having a larger proportion of exonic DNA than of intronic DNA. its being acted upon by natural selection. having a large number of base pairs. its recent origin by a gene duplication event
Answer:
The answer is "The first choice".
Explanation:
The hypothesis of such a molecular clock says because DNA and protein sequences develop at a pace generally constant over time as well as between different organisms. The whole idea is thus incredibly beneficial and for estimation of the historical periods, if the molecular biological hypothesis is valid, then the most significant feature enabling DNA to act as a molecular clock it has a reliable mean mutation.

Reproduction for dolphins and badgers and people is more complicated because
A. we have to apply for a license before we can reproduce
B. have to find a partner
C. go through the cellular process of MITOSIS to produce sex cells.
Answer:
B. have to find a partner
Explanation:
When two badgers get together and fall in love, a sperm cell from the father which contains a copy of half of his DNA, only half, combines with the egg cell of the mother, which contains half a copy of her DNA. The result is a brand new cell with all the information to divide and grow up into a brand new badger. The new child matures to be similar to our parents, but also unique, because she developed some traits from her mother’s DNA, and some from her father. Her new combination of traits can be passed on to her children, and again.
Which of the following best describes the genetic material a person receives from his or her father?

Which of the following statements is MOST accurate: Group of answer choices Animals evolved during the Cambrian Explosion because the Earth was organized into a supercontinent called Pangea Animals evolved during the Cambrian Explosion because oxygen on Earth had become abundant Animals evolved during the Cambrian Explosion because the Earth had just recovered from an asteroid impact Animals evolved during the Cambrian Explosion because carbon dioxide on Earth had become abundant
Answer:
Animals evolved during the Cambrian Explosion because oxygen on Earth had become abundant.
Explanation:
Photosynthesis could be responsible for the rise in the amount of oxygen in the seas and atmosphere near the beginning of the Cambrian. This rise of oxygen concentration allowing the evolution of larger animals having complex respiratory and circulatory systems. So we can conclude that evolution in the physical and genetical characteristics of animals occur during the Cambrian Explosion.
what do you mean by photo synthesis
Answer:
photosynthesis is the process in which plants take sunlight water and soil then convert it to sugars that it uses for food

What are the characteristic of a cell?
Answer:
All cells have a cell membrane, cytoplasm, and DNA. cells differ in how their genetic information is contained. All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these characteristics serve to define life.

which feature of stem cells enable them to replace cells in tissues such as skin?
The feature of stem cell which enable them to replace cell in tissues are that they can divide indefinitely to generate new cells and they can convert into the different types of cells that make up the body as they divide.
What is a stem cell ?A stem cell is a cell that has the unique capacity to grow into different types of cells in the body.
They may be utilised in the future to replace cells and tissues that have been damaged or destroyed owing to illness.
Stem cells are classified into three types which are Embryonic stem cells, Adult stem cells, Induced pluripotent stem cells.
Embryonic stem cells provide new cells to an embryo as it grows and develops into a newborn.
Adult stem cells generate new cells as an organism matures and replace damaged ones.
Induced stem cells are stem cells created in the laboratory by scientists.
