are genetic disorders always inherited? why or why not?

Answers

Answer:

They are not always inherited.

Explanation:

The reason a person gets genetic disorders is because of a mutation in a gene. This will affect the person from birth. This gene cannot always be passed on through the next generation, but it will stay as a possibility because the child still acquires the genes of the parent. These mutated genes could have a possibility of not being dominant, therefore making it recessive. So it is NOT always inherited.

Answer:Genetic disorders 'may or may not be inherited' based on if the body has 'developed antibodies' over time with 'evolution'' .

Explanation: A genetic disorder does not always have to be inherited if the body of the human has developed required antibodies and with proper lifestyle genetic disorder can be curbed. However if person keeps following normal lifestyle and does not take any steps to avoid the rise of genetic disorder they are more prone to the disorders

compare and contrast hormonal regulation during pregnancy and hormonal regulation during the menstrual cycle.

Answers

Answer: In summary, hormonal regulation during pregnancy and the menstrual cycle share some similarities, but differ in their goals, hormones involved, hormonal feedback loops, and timing.

Explanation: Hormonal regulation during pregnancy and the menstrual cycle are both complex processes involving several hormones, but they differ in their overall goals and mechanisms. Here are some key differences:

Goals: The primary goal of hormonal regulation during pregnancy is to maintain the pregnancy and support the growth and development of the fetus. In contrast, the primary goal of hormonal regulation during the menstrual cycle is to prepare the body for a possible pregnancy.

Hormones involved: Both processes involve the hormones estrogen and progesterone, but the levels and roles of these hormones are different. During pregnancy, the placenta produces high levels of estrogen and progesterone, which help maintain the pregnancy and prepare the body for childbirth. During the menstrual cycle, estrogen and progesterone are produced by the ovaries, and their levels fluctuate throughout the cycle.

Hormonal feedback loops: Hormonal regulation during pregnancy involves a positive feedback loop, in which rising levels of hormones signal the body to produce even more hormones to maintain the pregnancy. In contrast, hormonal regulation during the menstrual cycle involves a negative feedback loop, in which rising levels of hormones signal the body to reduce hormone production.

Timing: Hormonal regulation during pregnancy is a continuous process that lasts for nine months, while hormonal regulation during the menstrual cycle occurs on a monthly basis.

The main hormones involved and the general goals of hormonal management during pregnancy and the menstrual cycle are different.

                Pregnancy: Human chorionic gonadotropin (hCG), a hormone generated by the placenta, is the main hormone involved in pregnancy. Hormonal control during pregnancy serves to support the foetus' growth and development, preserve the uterine lining, and stop menstruation. Progesterone and oestrogen, among other hormones, are essential in sustaining pregnancy because they help the foetus develop and prepare the body for childbirth.

             

               Menstrual Cycle: Hormones such follicle-stimulating hormone (FSH), luteinizing hormone (LH), oestrogen, and progesterone control the menstrual cycle. Menstruation, the follicular phase, ovulation, and the luteal phase are some of the various phases that make up the cycle. Hormonal control during the menstrual cycle serves to prime the uterus for prospective implantation and fertilisation. Throughout the cycle, levels of oestrogen and progesterone rise and fall, affecting the uterine lining's thickening and shedding.

Why is important for commercial fishermen to have special fishing licenses and be limited to fishing during only certain seasons?

Answers

Answer: it is important to have a fishing license because the law doesnt want people fishing for big fish they want to keep it at a size and weight

Explanation:

i am a fisher man ik

It is important for commercial fishermen to have a special fishing license because that way researchers can track how many licenses they give. This way the fishermen don’t wipe out all of the fish. They have limits so it is easier to track the fish population. Without limits people would keep fishing and more people would do it. This would affect the whole fishing population and the whole food chain would go hay wire. That then effects us and what do you know? We have little to no food to eat. Let alone the animals.

Hope this helps! Always remember to get your fishing license if you are 16 or older!

Does the pattern in a food chain support the conclusion that climate change is caused by human activity and deforestion? Why or Why not?

Answers

Answer: No, it does not directly.

Explanation:

The pattern in a food chain cannot directly support the conclusion that climate change is caused by human activity and deforestation, as food chains only describe the transfer of energy and nutrients between different organisms in an ecosystem. However, the impacts of climate change and deforestation can disrupt food chains and have cascading effects on ecosystems, which can ultimately lead to the extinction of certain species and the loss of biodiversity.

Human activities, such as burning fossil fuels, deforestation, and agricultural practices, contribute to the emission of greenhouse gases, which trap heat in the atmosphere and cause global temperatures to rise. This increase in temperature can have a range of effects, including changes in precipitation patterns, rising sea levels, and more frequent and intense extreme weather events.

These changes can disrupt the habitats and food sources of many species, causing declines in their populations and even extinction in some cases. For example, deforestation can lead to the loss of habitat for many species, including those that are important components of food chains. Additionally, changes in precipitation patterns can affect the growth of plants and the availability of food for herbivores, which can then impact the populations of predators that depend on these herbivores for food.

In summary, while the pattern in a food chain itself does not provide direct evidence for the causes of climate change, the disruption of food chains and ecosystems due to human activities and deforestation can contribute to climate change and its impacts.

No, a food chain's pattern does not conclusively prove that human activity and deforestation are to blame for climate change.

            The pattern in a food chain does not necessarily prove that human activity and deforestation are to blame for climate change. Natural processes, greenhouse gas emissions, changes in land use, and other factors are only a few of the many influences on the complex phenomenon known as climate change. While human actions like burning fossil fuels can raise greenhouse gas concentrations and deforestation can lessen carbon sinks and release stored carbon into the atmosphere, these factors cannot simply be attributed to the pattern in a food chain.

         A thorough examination of the diverse scientific facts and evidence from numerous disciplines, such as atmospheric sciences, climatology, and earth sciences, is necessary to comprehend and handle climate change.
