A factory uses lake water as a system coolant, then returns the water, causing thermal pollution. Why is this a problem?A. The water returning to the lake carries chemicals from the factory.B. The water returning to the lake carries coolant toxins with it.C. The water returning to the lake carries pathogens from the factory.D. The water returning to the lake reduces oxygen levels in the lake.
Answers
Thermal pollution directly affects only the temperature of the lake. Hence, neither chemicals, toxins nor pathogens are added to the lake by the factory. However, high temperatures may deacrease the amount of dissolved oxygen in the water. Thus, the correct answer is D.

3.3 The inheritance of fur colour in cats is sex-linked. The tortoise-shell colour of cats is a combination of black and orange fur.

Answers
Answer:
The inheritance of fur color in cats is indeed sex-linked. The tortoise-shell color is a combination of black and orange fur. The allele for black fur is represented by X³ and the allele for orange fur is represented by Xº. When a female cat with a tortoise-shell color mates with an orange male cat, the genetic cross can be represented as follows:
Xº Y
X³ X³Xº X³Y
Xº XºXº XºY
The proportion of the F₁ phenotypes would be 1:1 for females (50% tortoise-shell and 50% orange) and 1:1 for males (50% black and 50% orange).
Male kittens can never have the tortoise-shell color because they only inherit one X chromosome from their mother. Since the alleles for black and orange fur are both located on the X chromosome, male kittens can only inherit one or the other, but not both.
Female kittens can have the tortoise-shell color because they inherit one X chromosome from each parent. If they inherit the X³ allele from one parent and the Xº allele from the other parent, they will have both black and orange fur, resulting in a tortoise-shell color.

Answers
Answer:
Explanation:
Preventive measures can be used to mitigate land-use problems by implementing policies and practices that focus on sustainable land management, conservation, and responsible development. This can include measures such as land-use zoning, environmental impact assessments, sustainable agricultural practices, afforestation, protected areas, and promoting public awareness and education about responsible land use. By proactively addressing potential issues and promoting sustainable practices, preventive measures help minimize negative impacts on land resources, ecosystems, and communities.

Chemical changes result in a new substance, but keep in mind that no new atoms are created. Existing atoms rearrange as chemical bonds break and new bonds form. That’s what creates the new substance.

40 divisions on the scale of an eyepiece graticule correspond to 16 small divisions on the stage micrometer. Each small division on the stage micrometer = 10 μm. 4 cells fit across 40 divisions of the eyepiece graticule. The length of each cell is: A 10 μm Β 40 μm C 40 mm D 10 mm
Answers
The length of each cell in the eyepiece division is option B which is 40 μm
Eyepiece division calculation.
In a microscope, the eyepiece graticule is a scale located in the eyepiece that helps to measure the size of microscopic objects. The stage micrometer, on the other hand, is a calibrated scale on the microscope stage that is used to calibrate the eyepiece graticule.
To determine the value of each eyepiece division on the stage micrometer, we use the following formula:
Value of each eyepiece division = (Value of each stage micrometer division) x (Number of stage micrometer divisions per eyepiece division)
The calculation can be done using the formula:
Length of one eyepiece division = (Length of one stage micrometer division) x (Number of stage micrometer divisions per eyepiece division)
Length of one eyepiece division = 10 μm x (16/40) = 4 μm
Since 4 cells fit across 40 divisions of the eyepiece graticule, the length of each cell is:
Length of each cell = Length of one eyepiece division x 4 = 4 μm x 4 = 16 μm
Therefore, the answer is B) 40 μm by calculating the value of each micrometer.

interpret what data means about the otter’s role in the kelp forest. what is the percent fish in diet? (otters present) what is the percent fish in diet? (otters absent) what is the percent of invertebrates in diet? (otters present) what is the percent of invertebrates in diet? (otters absent)
Answers
In general, otters play a crucial role in maintaining the health of kelp forests. They are considered a keystone species because they feed on sea urchins, which are known to graze on kelp.
Without otters, sea urchin populations can grow unchecked and damage the kelp forest ecosystem. By keeping sea urchin populations under control, otters help maintain the balance between kelp and other organisms in the ecosystem.
The percentage of fish and invertebrates in the otter's diet can vary depending on their location and availability of prey. Otters are known to be opportunistic feeders and will consume a variety of prey depending on what is available. Studies have shown that otters can consume a range of invertebrates, including crabs, clams, and snails, as well as fish species such as rockfish and herring.
In general, when otters are present, there may be a lower percentage of sea urchins and a higher percentage of fish and invertebrates in the ecosystem.
Conversely, when otters are absent, the sea urchin population may grow unchecked, leading to a decline in kelp and potentially impacting other species that rely on the kelp forest ecosystem.

If a corn plant had Yellow kernels and a smooth seed shape, what could it's possible genotype be? Choose all that apply
Answers
Corn kernels' color and shape are coded by diallelic genes expressing complete dominance. The genotype of individuals carrying Yellow kernels and a smooth shape phenotype can be either ppSS or ppSs.
What is complete dominance?
Complete dominance refers to the inheritance pattern in which the dominant allele of a gene completely masks the expression of the recessive allele.
The presence of at least one dominant allele is enough to express the dominant trait. This becomes evident in heterozygous individuals.
In the exposed example, two traits are involved. One of them is the kernel color and the other one is the kernel shape.
Genes coding for each of the traits express complete dominance,
P codes for purple and is dominant over p that codes for yellow.S codes for smooth and is dominant over s that codes for wrinkled.If a corn plant had Yellow kernels and a smooth seed shape, it is expressing the recessive phenotype for color (pp) and the dominant phenotype for shape (SS or Ss), so the possible genotypes are,

The purpose of the lab is to identify the structures of the digestive and circulatory systems in a rat.
How to explain the informationThe digestive system of a rat is similar to that of other mammals. It consists of the mouth, esophagus, stomach, small intestine, large intestine, and rectum. The mouth is where food is chewed and mixed with saliva.
The esophagus is a muscular tube that carries food from the mouth to the stomach. The stomach is a muscular sac that churns food and mixes it with gastric juices. The small intestine is a long, coiled tube that absorbs nutrients from food. The large intestine absorbs water from food and stores waste products. The rectum is a muscular tube that carries waste products from the large intestine to the anus.
The gallbladder is absent in rats because they have a different diet than other mammals. Rats eat mostly plant matter, which does not require as much bile for digestion as a diet that is high in protein. Bile is a fluid that is produced by the liver and stored in the gallbladder. It helps to break down fats in food.

The statement that best describes the population size between 1990 and 2011 is many increases and decreases but declined overall. Thus, the correct option for this question is B.
What is Population?The population may be defined as the group of individuals belonging to the same species living in the same area at a definite time. The size, density, dispersion, abundance, birth rate, death rate, etc. are the characteristics of the population. These characteristics are also known as demographic factors.
The gray fox is a species of carnivorous mammal of the Canidae family distributed by the American continent, from the south of Canada to Venezuela. Gray foxes are hunted, it is not as common as in other types of foxes, since the degree of their coats is perceived as inferior in quality.
