0.25 recessive alleles are present in your overall population.
What are recessive alleles?In terms of genetics, the term "recessive" describes the connection between an observed trait and the two inherited forms of a gene associated with that feature.
Each gene has two alleles that an individual inherits from each parent. When a characteristic is recessive, both of the (recessive) alleles of the gene that causes the trait must be present for the trait to manifest. When there is only one copy of an allele, it has no effect at all.
This is in contrast to a dominant trait, which can only be expressed when one of the two alleles is present.
Therefore, 0.25 recessive alleles are present in your overall population.

5. Knowing that acid rain has a pH of 2-3, would you conclude that crop species with a narrow soil pH range are in trouble? Is acid rain a problem for plant species and crops?
Answers
Answer:
Yes
Explanation:
Unless the crops acidity range is that of the rain( which it wouldn't be) it would throw off the crops Ph balance and harm it.
Yes, crop species with a narrow soil pH range are potentially in trouble due to acid rain. Acid rain can have harmful effects on plant growth and productivity. The acidity of the rain can change the pH level of the soil, making it more acidic and less hospitable for plants.
What is acid rain?Acid rain is a type of rain or other precipitation that is unusually acidic and has elevated levels of hydrogen ions (low pH). It is caused by the release of sulfur dioxide (SO2) and nitrogen oxides (NOx) into the atmosphere, which then reacts with water vapor to form sulfuric acid and nitric acid.
These acids can fall back to the ground as acid rain or other forms of precipitation and can cause harm to plants, animals, and infrastructure. Acid rain can also contribute to soil and water pollution and can have negative impacts on human health.
Acidic soil can also release toxic substances, such as aluminum, which can further damage plant roots and reduce plant growth. In addition, acid rain can damage plant foliage directly, leading to reduced photosynthesis and reduced yields.
So, acid rain can be a significant problem for plant species and crops, particularly those with a narrow soil pH range.

Two parrots have different parents. One parrot has red chest feathers, and the other parrot has yellow chest feathers. Why do the parrots have different feather colors on their chest?
Answers
Answer:
Hereditary traits.
Explanation:
Since these two parrots (with two different parents), one with yellow feathers and the other one red, it would make sense that they inherited their traits from their parents.
Just as humans have different colors of hair. Parrots can have different chest colors. Both of these come from hereditary genes.

Describe the physiological process of hunger. Include a discussion about glucose, the hypothalamus, set point, ghrelin/leptin, and basal metabolic rate in your response. Then, describe the cultural and situational factors that influence hunger.
Answers
Answer:
Ghrelin is made in the stomach. It stimulates hunger by entering the brain and acting on the neurons in the hypothalamus to increase the activity of the hunger-causing nerve cells and reducing the activity of hunger-inhibiting cells. As the stomach empties, the release of ghrelin increases. Leptin is a protein produced by fat cells that is a hormone acting mainly in the regulation of appetite and fat storage. When your blood sugar levels are too low, your cells become starved for energy. At first, you might notice minor symptoms, such as hunger and headaches. However, if you don’t get your blood sugar levels up in time, you may be at risk for serious complications. Introducing more glucose into your body will help solve the problem of low blood sugar. Our hunger is influenced not only by our physical state but also by our memory of when we last ate and our expectation of when we should eat again, this is what the hypothalamus does. According to set point theory, after a time, your body will fight reduced calorie intake by sending signals (hunger indications) and slowing down your metabolism to attempt to bring you back to your normal set point. Basal Metabolic Rate is the number of calories required to keep your body functioning at rest. BMR is also known as your body's metabolism; therefore, any increase to your metabolic weight, such as exercise, will increase your BMR. Everyone's basal metabolic rate is different. Although we humans as a species prefer certain tastes (such as sweet and salty), we learn to satisfy those preferences with specific foods eaten in the context of our families and our culture. Some of our taste preferences, such as the avoidance of new foods or of foods that have made us ill, have survival value.

Ghrelin is made in the stomach. It stimulates hunger by entering the brain and acting on the neurons in the hypothalamus to increase the activity of the hunger-causing nerve cells and reducing the activity of hunger-inhibiting cells.
Which cells are responsible for hunger?
Ghrelin is a multifaceted gut hormone which activates its receptor, growth hormone secretagogue receptor (GHS-R). Ghrelin's hallmark functions are its stimulatory effects on food intake, fat deposition and growth hormone release. Ghrelin is famously known as the “hunger hormone”.
Moreover, when food is scarce, some brain cells begin to devour themselves, activating an appetite-stimulating molecule in the process. A brain region called the hypothalamus contains neurons that regulate feeding in response to nutritional signals.
Therefore, within the hypothalamus are nerve cells that, when activated, produce the sensation of hunger. They do so by producing two proteins that cause hunger: neuropeptide Y (NPY) and agouti-related peptide (AGRP). Quite close to these nerve cells is another set of nerves that powerfully inhibit hunger.

c Different genetic makeups (phenotypes) can lead to the same physical traits (genotype)
d Different genetic makeups (genotypes) can lead to the same physical traits (phenotype)
Answers
Answer:
I think it is C (Different genetic makeups can lead to the same traits.)
Explanation:
An organism's genotype is the combination of alleles found at a particular gene. The phenotype is how theses alleles are expressed to form a trait.
In a diploid organism there are two alleles for every gene. In simple Mendelian traits. one allele is dominant over the other, which is recessive. That means, that the phenotype displayed will be associated with the dominant allele whenever it is present.
phetotypes is physical looks. people look similar but have different genotypes you get what im saying, because one genotype gets masked over the other. like blond and black come together black will win but blond is still in genes so thats how this would work ;)

Meiosis reduces chromosome number and rearranges genetic information. Explain how reduction and rearrangement are accomplished in meiosis. Include at least 3 ways this happens.
Answers
Answer:
Following are the solution to the given question:
Explanation:
Reduction: Throughout Meiosis I, in mitosis, two pairs pair and separate and transfer towards opposites throughout prometaphase I. Before Metaphase ii they separate the chromosomes during Metaphase II. There's also no gene replication between meiotic division I and meiosis II, and the resultant genomes have lower genetic data (chromatids) than parent organisms.
Through meiosis, genomes are formed in homologous pairs, in mitosis I and II. The spontaneous arrangement of helices with both the plate is the dependent result. During prometaphase I and II, the genomes divide so each gamete earns one of every chromos form. In Interphase I, tetrad interaction occurs throughout chiasma, contributing to genetic diversity.
