calculate the surface area of a sphere with a radius of 2 meters
Answer:
16[tex]\pi[/tex]
Explanation:
the surface area of a sphere is 4[tex]\pi[/tex]r^2
so r as 2 would mean the surface area is 16[tex]\pi[/tex] or about 50.265 meters squared.

As trees grow over time, the trees form new cells in circles called annual growth rings. These rings show the amount of
wood produced during one growing season or year, as well as the effects of different environmental conditions on the
tree. The figure shows the growth rings for two different types of trees growing in the same forest area
Due to differences in age and growth rate of the trees, the growth rings for two different types of trees growing in the same forest area may vary.
What are annual growth rings?Annual growth rings are rings of cells which form as trees grow over time and these rings represent the amount of wood produced during on growing season.
Annual growth rings provides estimates of the age of trees.
Distinct annual growth rings are formed in trees growing in temperate regions where there are sharp climatic variations.
The diameter and thickness of growth rings of different trees vary since trees grow and different rates.
Therefore, the growth rings for two different types of trees growing in the same forest area may vary due to differences in age and growth rate of the trees.

Two brown eyed parent have two childron with blue eyes. Give the genotypes of
each family member.
Albinism (lack of pigment) in humans is caused by a recessive gene. If normal
parents have an albino child, what is the probability that their next child will be
normal for pigment color?
Image result for Two brown eyed parent have two children with blue eyes. Give the genotypes of each family member.
The only way to present blue eyes is to inherit two copies of the blue-eyed gene. However, brown-eyed parents can pass a recessive blue-eyed gene. Therefore, two brown-eyed partners can birth a blue-eyed baby.

Answer:
I would say habitat planner and land planner
Explanation:
I picked habitat planner and land planner to do because I am an artist and a designer and I know how to put things together properly and for people to be like "Wow this is a beautiful piece right here" I would make it beautiful for the person's eyes when doing this you need to think about how a person might look at it I would want them to gasp and stare astonished and amazing and I could do that I've been practicing design for awhile now so If I were to pick these two things it is what I would do and also I really like nature and designing things with nature that others haven't thought about because it shows my creativity and ability to look beyond the point of just seeing.
If I could choose any career in ecology, I would pursue a career as a habitat planner.
Who is a habitat planner?This profession would allow me to contribute to the conservation and restoration of natural habitats, ensuring the well-being of various species and ecosystems. As a habitat planner, I would have the opportunity to assess existing habitats, develop conservation strategies, and collaborate with stakeholders to implement effective management plans.

Advantage: altering a component in the cell walls, causing the contents of the fungal cells to flow out and the cells to perish. inhibiting fungal cells from multiplying and expanding.
Disadvantage: An allergic response may cause swelling of your face, neck, or tongue, as well as breathing difficulties. a severe skin reaction, such as blistering or peeling. Loss of appetite, vomiting, nausea, jaundice, dark urine or pale feces, weariness, or weakness are all symptoms of liver impairment.
Antifungal medicines are used to treat fungal infections, which most commonly affect your skin, hair and nails.
You can get some antifungal medicines from a pharmacy without needing a GP prescription.
Some fungal infections can grow inside the body and need to be treated in hospital.
Antifungal medicines work by either:
killing the fungus
preventing the fungus from growing
Before taking antifungal medicines, speak to a pharmacist or GP about:
any existing conditions or allergies that may affect your treatment for fungal infection
the possible side effects of antifungal medicines
whether the antifungal medicine may interact with other medicines you may already be taking
whether your antifungal medicine is suitable to take during pregnancy or while breastfeeding – many are not suitable
You can also check the patient information leaflet that comes with your antifungal medicine for more information.

Brown coat color rabbits possess the dominant allele B, and white coat color rabbits possess the recessive allele b. If the frequency of the allele for white coat color is 0.04, what is the frequency of the dominant allele in the population?
Assuming Hardy-Weinberg equilbrium, we have
p + q = 1
where p = frequency of dominant allele and q = frequency of recessive allele. So
p = 1 - q = 1 - 0.04 = 0.96
Consequently we have
• p² = 0.9216 = frequency of hom ozygous domininant genotype
• pq = 0.0768 = frequency of heterozygous genotype
• q² = 0.0016 = frequency of hom ozygous recessive genotype
since
p² + 2pq + q² = 1

what happens if too much water is reabsorbed into the blood from the material in the large intestine and the problems this can cause.
Answer:
More ADH will be released, which results in water being reabsorbed and small volume of concentrated urine will be produced. If a person has consumed a large volume of water and has not lost much water by sweating, then too much water might be detected in the blood plasma by the hypothalamus.
Explanation:
If too much water is reabsorbed into the blood from the material in the large intestine, it can lead to dehydration.
The large intestine is responsible for absorbing water and electrolytes from the indigestible material that remains after digestion in the small intestine. Under normal circumstances, the amount of water that is reabsorbed is carefully regulated to ensure that the body stays hydrated and that the consistency of the stool is appropriate.
However, if too much water is reabsorbed, it can lead to dehydration, which can cause a variety of symptoms and problems. These may include:
Dry mouth and thirstDark yellow urineDry skinHeadachesFatigueConstipationDizziness or lightheadednessIncreased heart rateDehydration can be caused by a variety of factors, including not drinking enough fluids, sweating excessively, or having diarrhea. It is important to drink enough fluids and replace lost electrolytes to prevent dehydration. In severe cases, dehydration may require medical treatment.
