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.)
Answers
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!

C. A Chameleon changing color when entering a different environment.
D. An organism dying because it is not adapted to its habitat.
Answers
Answer: B
Explanation: because it adapt to its environment to survive
The development of an organ system like a vascular system over a long period of time in plants is an example of evolution. Thus option A is correct.
What is evolution?Evolution is a series of events that have taken place in several years to make the species more advanced for the environment due to the introduction of multiple mutations in the genetic sequence.
During evolution, plants have gained the genetic mutation that codes for the vascular system which provide support and transports water in plants. So option A is correct.

Do the spinal nerves include the sensory or motor neurons? Where do these neurons enter or exit the spinal cord?
Answers
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.

Describe the intermolecular interaction of the surface carboxylate groups of a micelle and the surrounding water.
Answers
Answer:
Hydrophilic portions are outside and hydrophobic regions are inside
Explanation:
A micelle is an assembly of amphiphilic molecules formed in a liquid solution, generally an aqueous solution. Micelles are formed due to the packing (aggregation-like) behavior in which single-tail lipids are organized in a bilayer. A typical micelle in aqueous solution forms a spheric assembly where carboxylate ions are organized in a mode that hydrophilic head regions enter in contact with the surrounding water, while hydrophobic (lipophilic) portions are disposed inside the micelle.
Mutations in which of the following cells would get passed on to the next generation?
I. sperm
II. Skin cell
III. Egg
IV. Neuron
A. II, III, and IV
B. III only
C.I and III
D. I, III, and IV
Answers
Answer:
C. I and III
Explanation:
A mutation needs to occur in a gamete cell in order to be passed down to the next generation.
If it occurs in a somatic (body) cell, the mutation will only be present in that organism.
On the other hand, in a gamete cell, the mutation will pass down because gamete cells are directly involved in the genetic makeup of the offspring.
So, since sperm and egg cells are gametes, mutations in those cells would get passed on.
The correct answer is C. I and III
Explain what, if any, is the issue facing DNA polymerase in regards to its 5’->3’ activity when replicating DNA.
Answers
Answer:
The two strands of DNA are replicated in different ways
Explanation:
DNA replication is a process that occurs during the S phase of the cell cycle that consists of making two identical copies of the double-stranded DNA molecule, which subsequently are distributed in the daughter cells during cell division. During this process, DNA polymerase can add nucleotides in 5' to 3' direction, but not in 3' to 5' direction. In consequence, the DNA strand that has 3’ to 5’ directionality can be synthesized directly, while the DNA template strand that has 5’ to 3’ directionality can't be synthesized in a continuous manner and thereby it is created by adding small DNA fragments, which are known as Okazaki fragments (150-200 nucleotides in size).

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
Answers
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.

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.
