how gravity plays a role in the parts of the water cycle shown in this model.
Answer:
look dear i will explain
Explanation: It pulls precipitation down from clouds and pulls water down hill . gravity also moves air and ocean water. Gravity pulls denser air and water downwards,forcing less dense air and water o move upwards.
okay hope it works
Hit like
Answer:
Gravity causes precipitation in the clouds to fall to Earth. On the ground, gravity influences surface runoff, as water travels from higher to lower elevations. Gravity also influences groundwater because it pulls elements toward the center of Earth. Water, under the influence of gravity, seeps into the ground to form groundwater.

You classified organisms based on anatomical structure and development. Scientists also use DNA to classify organisms. Considering the basic process of evolution, why do you think it’s important to also consider DNA and gene patterns during the classification of organisms?
Answer:
By studying genetics and DNA, we can get the best idea of how species are related to each other, and therefore how to classify them. The genetic code of a species is not fixed, however. It changes over time! This is why we also need to factor in evolution.

Which of the following is not a function of the digestive system? Select one: A. mechanical processing B. absorption C. secretion D. ingestion E. filtration
Answer: option E.
Filtration.
Explanation:
Digestive system consist of the gastrointestinal tracts, organs that help to breakdown large complex consumed food into to small pieces which can easily be absorbed by the body.
Filtration is not a function of digestive system because it play a major role in circulatory system which help in movement of solutes out of the capillary into interstitial fluid by separating the bigger particles from the smaller particles, filtering out nitrogenous waste and regulating salt concentration .
Do the spinal nerves include the sensory or motor neurons? Where do these neurons enter or exit the spinal cord?
Answer:
hd
Explanation:
The spinal nerves include the sensory or motor neurons sensory neuron → brain → motor neuron → muscles.
What are neurons?Neurons are nerve cells that are specialized to process and transmit information. The brain then processes the information obtained from the sensory neuron and sends another signal trough the motor neuron carrying the message to the muscle.
The spinal cord acts as a nerve center between the brain and the rest of our body and it contains motor neurons that transmits nerve signals from the motor cortex to the body, and the spinal cord also receives all of the sensory information from the periphery of our bodies.
Motor neurons are also known as efferent neurons, they are part of the central nervous system that transmit impulses from the brain or spinal cord to the effector organ (muscles or glands).
Therefore, The spinal nerves include the sensory or motor neurons sensory neuron → brain → motor neuron → muscles.

gene controls if the stripes are thick or thin. Thin (T) is dominant over
thick (t). If two snakes heterozygous for this gene are crossed, what will
be the genotype(s) of their offspring? You may need to use a Punnett
square to answer the question.
Question Progress
OA. TT and Tt
B. TT, Tt, and tt
C. TT and tt
D. All Tt
The genetic attributes of the organism are determined by the genotype. The cross of the heterozygous genes in Coral snakes results in offsprings with TT, Tt, and tt. Thus, option B is correct.
What are genes?Genes are the functional and physical basis of the inheritance that passes from generation to offspring with various traits and attributes. The gene contains a recessive and a dominant allele.
Heterozygous genes are represented as Tt as it contains one dominant and one recessive allele. The cross between the two heterozygous (Tt) Coral snakes is attached to the image below.
From the cross, it can be seen that 75 % of the coral snakes have thin strips while the 25 % of the species have thick strips. The ratios are:
Genotype = 1 : 2 : 1
Phenotype = 1 : 3
Therefore, option b. the genotype(s) of the offspring will be TT, Tt, and tt.

a) preparing meals using solar cookers.
b) switching from wood to burning crop waste as a fuel source.
c) adding more windows to houses as a source of ventilation.
d) passing a green tax to make homeowners pay for their pollution.
e) providing asthma inhalers to children under the age of 12 years.
Answer:
preparing meals using solar cookers.
Explanation:
solar cookers radiates at low rates.Therefore the most of the nutrients in the foods are conserved.Thus most micro nutrients for biochemical activities are retained. Vitamins which can not withstand high temperature are preserved.
Most importantly carcinogens which are usually associated with high heat foods are avoided ,when cook with low heat of solar cookers
The solar cooker is smoke free,therefore irritation of the lungs,lung cancer associated with high heat cookers is avoided.
Specifically,local Mayan women exposed to high heat smoke cookers, suffers lung cancer,and those with pregnancy gives to infants with low birth weights. Children exposed to theses high heat also experienced acute lower respiratory infections.
Thus the smokeless,low heat solar cooker is safer.
2. Calculate the rate of population increase for the whales and the seals from the data in table 2, trial 1. What does this rate represent?
Hint: From the point of zero change on the graph to the highest population achieved is a change in time of 100 months. (Refer to the science skills practice in the lesson for the correct formula for the rate of population change.)
Answer:
There are no tables but it should be a bell curve. as a population of whales rise the population of seals will decrease, eventually creating a plateau in the whale population. shortly after the plateau in the whale population the whale population will begin to decline ( as food becomes less available) causing the seal population will begin to rise and restabilize. this pattern should continue cyclically creating a wave function on a graph!

In a population of flowers growing in a meadow, C1 and C2 are autosomal codominant alleles that control flower color. The alleles are polymorphic in the population, with f (C1) = 0.8 and f (C2) = 0.2. Flowers that are C1C1 are yellow, orange flowers are C1C2, and C2C2 flowers are red. A storm blows a new species of hungry insects into the meadow, and they begin to eat yellow and orange flowers but not red flowers. The predation exerts strong natural selection on the flower population, resulting in relative fitness values of C1C1 = 0.30, C1C2 = 0.60, and C2C2 = 1.0.
Required:
a. What is the C1C2 genotype frequency among the progeny of predation survivors?
b. What is the C2C2 genotype frequency among the progeny of predation survivors?

Using specific examples, discuss the roles of negative and positive feedback processes that maintain homeostasis.
Answer:
Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values, known as set points. In contrast to negative feedback loops, positive feedback loops amplify their initiating stimuli, in other words, they move the system away from its starting state.
If a mother is affected by an X-linked dominant condition and the father is not, which children can inherit the condition?
only males
neither males nor females
both males and females
only females
Answer:
both males and females
Explanation:
The sex chromosomes in male and female humans are X and Y chromosomes. X-linked traits are those traits which are associated with the X- chromosome.
According to the question, the trait is passed on a X-linked dominant condition, which means that the possession or not of the condition is dependent on the presence of the dominant X-chromosome. The dominant X-chromosome will always express itself even when in an heterozygous state with a normal X-chromosome i.e Xx. Hence, only a individual recessive for the X-chromosome will be normal.
A mother that is affected by the X-dominant condition will either possess a; XX or Xx genotype while a father that is normal (not affected) will possess a (xY) genotype. Since the mother passes one of her X chromosomes to her sons and the other to her daughters, both male and female children will be affected by the condition.
N.B: If the mother is heterozygous for the affected X-chromosome (Xx), half of her sons and half of her daughters will inherit the condition but if the mother contains two dominant X-chromosomes (XX), all of her sons and daughters will inherit the condition.
