The half-life of a radioactive element, such as carbon-14, is the time it takes for half of the atoms of the element to decay. How many half-life periods have passed if a fossil contains 1 32 of the original amount of carbon-14?
Answer:
This half-life represents the time in which the number of radioactive nuclei falls to 1/2 of its starting value. Activity, being proportional to the number of active nuclei, also has the same half-life. Life of all the radioactive elements is infinite. Radioactive decay constant 'λ', of different elements different.

Explain how the lungs are adapted for diffusion of gases
Answer:
well u know how we breath air in its the same as gas so your lungs are used to narcotics like smoking and vaping and stuff
Explanation:
Answer: Gas exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. As shown below, inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli.
Explanation: The alveoli are adapted to make gas exchange in lungs happen easily and efficiently. they give the lungs a really big surface area. they have moist, thin walls (just one cell thick) they have a lot of tiny blood vessels called capillaries.
Please help me really quick
Answer:
gas particles are very losely packed then liquid
What are the target cells for the human Growth Hormone?
Answer:
Once released into the circulation, GH binds and activates the cell-surface GHR, as well as the related prolactin receptor in target tissues such as liver, muscle, bone, and adipose tissue
Explanation:
Direct effects are the result of growth hormone binding its receptor on target cells. Fat cells (adipocytes), for example, have growth hormone receptors, and growth hormone stimulates them to break down triglyceride and supresses their ability to take up and accumulate circulating lipids.
Answer:liver, muscle, bone, and adipose tissue I think

All cells have the SAME genes. True/False
Provide an example of this in humans: answer here
Answer:
Almost all of the cells in your body share the same DNA so false deku here! :3
Explanation:
Answer:
False.
Explanation:
All cells do NOT have the same genes due to genetic variation. The reason we have different genes for different cells is to allow the cells to do different things, otherwise all cells would perform the same function.

the roots of the gorse plant have bacteria that turn nitrogen gas into nitrate ions. Explain why nitrate ions are needed by the gores plant
Answer:
Nitrate ions are needed by the gores plant for photosynthesis and for producing proteins
Explanation:
Nitrates ion are essential for producing amino acid which in turn is used for producing proteins. Nitrates is taken up by plants through the roots. Nitrates is vey essential for the photosynthesis of the plants. Without nitrate a plant cannot carry out photosynthesis and hence will not be able to produce food for itself and other living beings.

You are a genetic counselor. A couple comes to you for advice. The female is pregnant with their first child. Both have family histories with Tay-Sachs disease, which is a disorder that progressively destroys nerve cells, leading to loss of motor skills, vision, and hearing. The disease is an autosomal recessive pattern. Which of the following statements is true?
The child will likely have Tay-Sachs disease if both parents pass on the recessive alleles.
The child will likely have Tay-Sachs disease if both parents pass on the dominant alleles.
The child will only have Tay-Sachs disease if the mother passes on the recessive allele.
The child will likely have Tay-Sachs disease if the father passes on the dominant allele.
Answer:
The answer is B: The child will likely have Tay-Sachs disease if both parents pass on the dominant alleles.
Explanation:
Brainliest pls!!
Answer:
The child will likely have Tay-Sachs disease if both parents pass on the recessive alleles.
Explanation:
With autosomal recessive diseases, if the offspring recieves two recessive alleles, they will exhibit the trait.

Which of the following is required for a trait to become more common
over time in a population? *
There must be many varieties of the trait in the population.
The trait must allow members of the population to eat only some kinds of foods.
The trait must be the result of an immediate change in the environment.
The trait must give individuals an advantage in producing offspring that survive.
Answer:Natural selection is a process that causes heritable traits that are helpful for survival and reproduction to become more common, and harmful traits to become more rare. This occurs because organisms with advantageous traits pass on more copies of these heritable traits to the next generation.
Explanation:
Predict the results if promoters were not part of the transcription process. Please explain in detail!
Answer:
In genetics, a promoter is a protein-binding DNA sequence that initiates the transcription of a single RNA from the DNA downstream. This RNA can encode proteins, or it can have mobile functions, such as tRNA, mRNA, or rRNA. The promoter is near the starting site of gene transcription, upstream of the DNA (towards the 5 'region of the sense strands). The promoters can consist of about 100–1000 pairs

A Circulatory and reproductive
B Immune and circulatory

A. introducing a new species to an ecosystem
B. natural disasters
C. hibernation
D. migration
Answer:
hibernation
Explanation:
the rest definitely does
Answer:
C. hibernation
Explanation:
Exponential growth assumes that environmental factors like food, water supply, space, shelter, disease organisms, predators, weather conditions, and natural disasters do not affect the birth or death rate. As long as birth rate exceeds death rate (even slightly) population size will increase exponentially.
