A. What kind of weather is associated with a low-pressure area?

B. What happens to the air of the low pressure areas that leads to this type of weather?

Answers

Answer:

A.) Low-pressure systems are usually associated with clouds and precipitation that minimize temperature changes throughout the day

B.) The slightly inward moving air in low pressure causes air to converge and since it can’t move downward because of the surface, the air is forced upward, leading to condensation and precipitation

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.

Why does each offspring get 2 alleles for a trait?

Answers

During meiosis, chromosome pairs are split apart and distributed into cells called gametes. Each gamete contains a single copy of every chromosome, and each chromosome contains one allele for every gene. Therefore, each allele for a given gene is packaged into a separate gamete.

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

                         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.

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.

The input of sewage, fertilizer runoff, and animal waste can cause the formation of Choose one: A. an algal bloom. B. nutrient-poor soil C. fertile farmland. D. an artesian well.

Answers

Answer:

An algal bloom.

Explanation:

The input of sewage, fertilizer runoff, and animal waste can cause the formation of an algal bloom (abundances of cyanobacteria)  because of the excess nutrients (nitrogen or phosphorus). If there are too much nutrients in the water (caused by the sewage, fertilizer runoff, and animal waste) it creates a perfect environment for excess growth, being an algal bloom. Algal blooms are toxic and are known to be harmful to the animals that rely on this source for their survival and humans as well.
