if a person is heterozygous for cystic fibrosis is married to someone who actually has the disease. What are the chances that their child will have CF?

Answers

Answer 1

Answer:

50%

Explanation:

CF is a recessive trait.  That means that an individual must have two copies of the recessive allele in their genotype in order to express the trait.  That means that the parent with CF has genotype cc, while the parent who is heterozygous, and does not express the trait, has genotype Cc.  Using a Punnett square to demonstrate the cross of these two parents will produce a probability of 50% heterozygous and 50% positive for CF.

Which of the following is NOT a result of global warming?

(societal conflicts)

(sea-level rise)

(loss of biodiversity)

(ozone depletion)

Answers

Ozone depletion is NOT a direct result of global warming. While both global warming and ozone depletion are environmental concerns, they are caused by different factors and have distinct impacts.

Global warming is primarily caused by the increased concentration of greenhouse gases in the atmosphere, trapping heat and leading to a rise in global temperatures. It results in a wide range of consequences, including the melting of polar ice caps, rising sea levels, extreme weather events, shifts in ecosystems, and the potential loss of biodiversity as species struggle to adapt to changing conditions.

On the other hand, ozone depletion is mainly caused by the release of certain chemicals known as ozone-depleting substances (ODS) such as chlorofluorocarbons (CFCs) and halons. These substances break down ozone molecules in the stratosphere, leading to the thinning of the ozone layer. Ozone depletion primarily affects the stratospheric ozone layer, which shields the Earth from harmful ultraviolet (UV) radiation. The thinning of the ozone layer can have detrimental effects on human health, ecosystems, and agricultural productivity.

Therefore, while global warming and ozone depletion are both significant environmental issues, ozone depletion is not a direct result of global warming.

DNA polymerase adds nucleotides at the 3' primer end of the DNA. This DNA polymerase checks the newly added base has correctly paired with the base in the template strand or not. Based on this it adds the new nucleotide.

What is nucleotide?

Nucleotide is the nucleoside with a phosphate group. It generally stack or link with each other to make a polynucleotide chain.

DNA polymerase adds these nucleotides one by one to the 3' primer end on the DNA strand.

Write a paragraph explaining how genetic variation, reproductive strategies and environmental pressures have impacted the survival of populations. Identify a specific example for each in your discussion.

Answers

Answer: Genetics and Pressures

Explanation:

For natural selection to occur, a population must have a wide variety of individuals with different traits. For example, natural selection would not influence fish body color if all individuals in a population were exactly the same color. Variation of scale color can help a fish species have a higher chance of survival by confusing predators as to what species they are.

Reproductive strategies represent a set of behavioral, morphological, and physiological adaptations that facilitate access to potential mates, improve the chances of mating and fertilization, and enhance infant survival. Male peacocks have bright, big tail feathers, for example, to attract females. If an organism has a high appeal, this will make them more likely to be able to meet and continue the survival of the species.

Environmental pressures, such as plant death, could influence the survival of herbivorous organisms. Say a small land creature consisted off grass, and an epidemic killed all the grass in their region. They would either die off, or they would evolve to find different types of food. The former could reduce population, while the latter could increase it.

Answer:

Explanation:

a biological taxon is spatially arranged. The geographic limits of a particular taxon's distribution is its range, often represented as shaded areas on a map. Patterns of distribution change depending on the scale at which they are viewed, from the arrangement of individuals within a small family unit, to patterns within a population, or the distribution of the entire species as a whole (range). Species distribution is not to be confused with dispersal, which is the movement of individuals away from their region of origin or from a population center of high density.
