Clouds water cycle pls tell me :)
Answer:
Clouds exist in the atmosphere because of rising air. As air rises and cools the water in it can "condense out", forming clouds. Since clouds drift over the landscape, they are one of the ways that water moves geographically around the globe in the water cycle.

Explanation:
Your friend Joe has a younger brother Sam and two older sisters. Sam has a strange disorder that has caused his hair to turn green. The doctor says that this is caused by a single gene that is inherited, and that boys are more likely to have green hair then girls. However Joe, his sisters, and both of his parents have normal hair color. Joe does not know much biology and is confused. Explain to Joe how his brother's condition could have arisen even though Joe has normal hair. Then discuss the likelihood that a) Joe, and b) Sam will have children with green hair. Assume that they both marry women with normal hair color. You will need to include information on meiosis and transmission of genes to assure that Joe understands. HINT: As part of your answer, indicate the percent of girls vs. boys that you predict would have green hair if fathered by Joe vs. Sam.
Answer:
The correct answer is - it is due to the case of sex-linked recessive disorder.
Explanation:
It is pointed out by the doctor that Sam has a condition due to recessive allele and it is given that boys have this condition more than girls which suggests that it is a sex-linked recessive disorder. This comes from their parents but it is given that the father has normal hair which means the father has no recessive allele, then it must come from the mother even mother has not this condition but she could be a carrier for this trait.
Joe and his sister do not have this condition as they get the normal dominant allele from mother and father.
The chances of being a carrier by his sisters are 50%. If Joe marries
IF Joe marries a non-carrier woman, he will have all normal children with no green hair. IF Joe marries a normal hair color carrier women then there would 25% chances of being diseased offspring and 50% chances of being a carrier, and if women is completely normal then all offspring will be normal.
carrier woman, his children will have a 25% chance of being green-haired. A 25% chance of being
IF Sam marries a normal woman, the children will have a 25% chance of being a carrier, a 25% chance of being green-haired, and a 50% chance of being normal.

The four main forces that drive evolution are mutation, natural selection, genetic drift, and gene flow. All of these forces can cause a change in what?
Answer:
Allele frequencies
Explanation:
The only component that is transmitted from generation to generation is the genetic material (genes), the fact that an individual leaves more descendants implies that their genetic variants (alleles) will be more represented in the next generation. The frequencies of the different alleles will change from one generation to another, and this change will be irreversible when the set of genes in the population is considered, since it is highly unlikely that a previous configuration will be returned in all gene variants. Hence, from a population point of view, evolution is ultimately a cumulative and irreversible change in the proportions of different gene variants in populations. The agents that change the allele (or gene) frequencies of populations, that is, factors of evolution, are mutation, genetic drift, migration, and natural selection. Mutation is a factor that increases genetic diversity. Natural selection is the process by which the gene frequencies involved with certain traits vary from generation to generation, since some variants of the trait have a greater capacity than others to survive and produce offspring. The mutation rate of a gene or DNA sequence is the frequency at which new mutations occur in that gene or sequence in each generation. In each generation there is a gene raffle during the transmission of gametes from parents to children which is known as genetic drift. In the absence of gene flow, gene drift will also lead to local differences in allele frequencies.

calculate power when work is 20 J and time is 2 s
Answer:
10W
Explanation:
Power is the "ability to make work over time", so to get the power, just divide work by time.
20J/2s = 10 J/s = 10W
Answer:
10 watts
Explanation:
Power= work done/time
Power= 20J/2s
Power= 10 watts
Give reason why the permeability of both the membrane is same for fatty acid?
Answer:
Because of the amphipathicity and conical molecular shape of fatty acids.
Explanation
They can efficiently incorporate into lipid membranes and disturb membrane integrity, chain packing, and lateral pressure profile. These phenomena affect both model membranes as well as biological membranes. We investigated the feasibility of exploiting fatty acids as permeability enhancers in drug delivery systems for enhancing drug release from liposomal carriers and drug uptake by target cells. Saturated fatty acids, with acyl chain length from C8 to C20, were tested using model drug delivery liposomes of 1,2- dipalmitoyl-sn-glycerol-3-phosphocholine (DPPC) and the breast cancer MCF-7 cell line as a model cell. A calcein release assay demonstrated a reduction in the membrane permeability barrier of the DPPC, proportionally to the length of the fatty acid. Differential scanning calorimetry (DSC) and dynamic light scattering (DLS) experiments revealed that C12 to C20 fatty acids could stabilize DPPC liposomal bilayers and induce large structures, probably due to liposome aggregation and bilayer morphological changes. On the other hand, the short fatty acids C8 and C10 tend to destabilize the bilayers and only moderately cause the formation of large structures. The effect of fatty acids on DPPC liposomes was not completely transferrable to the MCF-7 cell line. Using cytotoxicity assays, the cells were relatively insensitive to the fatty acids at apoptotic sub-millimolar concentrations. Increasing the fatty acid concentration to few millimolar substantially reduced the viability of the cells, most likely via the induction of necrosis and cell lysis. A bioluminescence living-cell-based luciferase assay showed that saturated fatty acids in sub-cytotoxic concentrations could not reduce the permeability barrier of cell membranes. Our results confirm that the membrane perturbing effect of fatty acids on model membranes cannot simply be carried over to biological membranes of live cells.

Which traits do you think are very strictly determined by your genetic make-up (genotype)?
Answer:
Reproduction, growth and development, regulation, homeostasis, and energy processing.
Explanation:
Reproduction, growth and development, regulation, homeostasis, and energy processing are the traits or characteristics that are determined by the genotype. These traits are under the control of genes of an organisms and can be changed if the change in the genes occurs while on the other hand, the physical characteristics of an organisms are determined by phenotype means phenotype is responsible for the appearance of an organisms.

Which statement correctly
compares humidity in warm and cold air?
A. Warm air holds less moisture than cold air.
B. Warm air will always hold the same amount of moisture as cold air.
C. Warm air can hold more moisture than cold air.
D. Neither warm or cold air can contain water vapor.
Answer:I believe it is c, it makes the most sense to me. I apologize if I’m wrong
Explanation:
The statement which correctly compares humidity in warm and cold air is that warm air can hold more moisture than cold air. Thus, the correct option for this question is C.
What is Humidity?Humidity may be defined as the amount of water vapor present in the atmosphere of living organisms or an ecosystem. If there is a lot of water vapor in the air, the humidity will be high. The higher the humidity, the wetter it feels outside. On weather reports, humidity is usually explained as relative humidity.
High humidity levels are more likely found in warm air. This is because warm air holds more water at higher temperatures. Due to this, warm air has the capacity to hold a lot of moisture.
But on contrary, fewer humidity levels are more likely found in cold air. This is because cold air holds less water at lower temperatures. Due to this, cold air does not have the capacity to hold a lot of moisture.
Therefore, the statement which correctly compares humidity in warm and cold air is that warm air can hold more moisture than cold air. Thus, the correct option for this question is C.
