the age of fossils can sometimes be determined by radiometric dating, which is based on the constant rate of decay of radioactive isotopes. the time required for half of a radioactive isotope to decay is called the half-life of that isotope. for example, the isotope carbon-14 has a half-life of 5,730 years.

Answers

Answer 1

Answer:

17,190 years Radiometric dating is a technique for determining the age of fossils that is based on the fact that specific radioactive isotopes decay at a constant rate.

Describe why enzymes are important in all living organisms?

Answers

Answer:

Enzymes are important because they make the chemical reactions in cells happen quickly.

Enzymes, by speeding up biological reactions, ensure that all necessary activities in a cell can take place simultaneously and prevent one particular activity from overtaking the entire cell or organism. This is possible because enzymes allow chemicals to react more specifically with only certain substances rather than reacting indiscriminately with any number of different substances within cells.

The most famous example of this enzyme effect is when stomach acid reacts with pepsin that turns food into a liquid. The body then uses this liquid for absorption through the intestines where nutrients are then used throughout the body. It's important for people to have enough enzymes in order to digest their food fully however if

how will climate change affect the habitat distribution for the baltimore oriole?

Answers

Climate change has a great effect on the habitat distribution of Baltimore orioles bird.

Climate change will adversely affected the habitat distribution of Baltimore orioles because climate change causes heat waves, wildfires and intense downpours which is harmful for Baltimore orioles.

The climate changes will limit the populations of ranges of Baltimore oriole as well as changes the habitat. These Baltimore orioles moved to other places where the climate is favourable so we can conclude that climate change has a great effect on the habitat distribution of Baltimore orioles bird.

What is the probability that a couple will have a type A child if the mother has Type
A blood and is heterozygous for the trait and the father has type AB blood?

Answers

Answer:

50%

Explanation:

To solve this, we'd need to use a Punnett square.  Since the mother has a heterozygous genotype and has an A-blood phenotype, we know that she is AO and the father is AB.

          A             B

A       AA           AB

O      AO           BO

According to this, the four possible blood types, with equal probability are: AA, AB, AO, and BO.  Both AA and AO genes will result in type-A blood, since A is dominant over O.  Therefore, there is a 2 in 4 (or 1 in 2, or 50%) chance of the child having type-A blood.

i got the answers off a quiz let

At the most basic level, schizophrenia is best conceptualized as a neurodevelopmental disorder.

It is characterized by a complex interplay of genetic, environmental, and neurobiological factors that disrupt brain development and function during early stages of life.

While the exact causes are not fully understood, research suggests that abnormalities in brain structure, neurotransmitter imbalances, and genetic predisposition contribute to the onset of schizophrenia.

These disruptions may affect cognitive processes, emotional regulation, and perception, leading to symptoms like delusions, hallucinations, disorganized thinking, and social withdrawal.

Understanding schizophrenia as a neurodevelopmental disorder highlights the importance of early detection, intervention, and holistic treatment approaches to improve outcomes and quality of life for individuals affected by this condition.

                         please mark as brainliest

In angiosperm double fertilization, one sperm nucleus fertilizes the egg to form the diploid zygote, and a second sperm nucleus fuses with the two nuclei in the central cell of the embryo sac.

The egg is the female gamete in an angiosperm. It is a haploid cell that contains one set of chromosomes. The zygote is the fertilized egg. It is a diploid cell that contains two sets of chromosomes. The zygote will eventually develop into an embryo. The central cell is a cell in the embryo sac that contains two haploid nuclei.

Double fertilization is a unique feature of angiosperms. It is a type of fertilization in which two sperm nuclei fertilize two different cells in the embryo sac. The first sperm nucleus fertilizes the egg to form the zygote. The second sperm nucleus fuses with the two nuclei in the central cell to form a triploid cell. This triploid cell will eventually develop into the endosperm, which is a food reserve for the developing embryo.
