Use the word bank below to complete the passage below describing mitosis and meiosis. All words will be used at least once and most words will be used more than once.A) diploidB) mitosisC) meiosisD) sister chromatidsE) haploidF) homologous chromosomes1) A male giant panda has 42 chromosomes in its skin cells. This represents the _________ chromosome number. As the animal's old skin cells die and slough off, cells nearby divide through _________ to produce more skin cells. 2) Germ cells within the animal's testicles undergo _________ to replicate themselves and _________ to produce sperm. 3) The cells produced by mitosis in this panda have a _________ chromosome number and are produced after _________ are pulled apart into separate daughter cells.4) The cells produced by meiosis I in this panda have a _________ chromosome number and are produced after _________ have been pulled apart into separate daughter cells. 5) The cells produced by meiosis II in this animal have a _________ chromosome number and are produced after _________ have been pulled apart into separate daughter cells.
Answer:
1. diploid ,Mitosis
2. mitosis, meiosis
3. diploid, sister chromatids
4. haploid, homologous chromosome
5. haploid, sister chromatids
Explanation:
1. The Giant Panda has 42 chromosomes but these chromosomes exist in the form of homologous pairs therefore the Panda are diploid organisms. The somatic cells of the Panda undergo mitosis like skin cells.
2. The Germ cells are present in the testicles of the Panda which makes an exact copy of themselves by mitosis but these germ cells undergo meiosis to produce sperms.
3. The Mitotic division forms two daughter cells with the same genetic material because the sister chromatids of homologous chromosomes move to the opposite pole.
4. The meiosis I am also known as reductional division as the homologous chromosome separate and move to opposite poles during meiosis I and the ploidy changes from diploid to haploid.
5. During meiosis II, the sister chromatids of a chromosome separate and move to the opposite poles as a result of this the haploid cells are formed.
A student plays football outside on a hot day and lost a significant amount of water in sweat. How will this affect his blood volume?
A.Blood volume decreases
B. Blood volume stays the same
C. Blood volume increases
Answer:
A.Blood volume decreases
Explanation:
Blood volume refers to the fluid substances including blood circulating in the body via blood vessels. The blood volume must be optimal in order to ensure that every organ in the body gets an ample amount of blood. One of the things that can result in alteration of the normal blood volume is DEHYDRATION, which is the loss of water from the body.
Dehydration decreases the blood volume because the water content in the blood becomes decreased as water is lost, which would have detrimental effects on the body because the blood pressure (force at which blood flows) will be reduced.
This is the case of the student in this question that loses a significant amount of water as sweat when he undergoes exercise in a hot weather condition. The loss of water will result in the decrement of his blood volume.

The deforested land will not be able to support large trees again.
Some species will develop adaptations to survive in the deforested land.
Some populations will migrate out of the deforested area.
Some animals will instantly adapt to the deforested environment.
Answer:
Some species will develop adaptations to survive in the deforested land.
Some populations will migrate out of the deforested area.
Explanation:
The deforested land will be able to support large trees eventually in the future, and animals cannot instantly adapt to anything.
Therefore, the most logical answers are populations will migrate to forest lands and species will eventually develop adaptations to help them in the newly deforested land.

Why do you think scouts could hear better through the solid ground rather than
through the air?
Answer:
Sound travels better through solids than through air.
Explanation:
Think about being in the pool: you can hear a lot of things, albeit muffled a little. Or think about tapping a really long pole, and someone standing far away can hear the vibration or the noise while touching the pole.
Solids are more tightly packed together. Sound needs a medium to travel though, and anything with densely packed atoms is better than loosely packed. The hierarchy is solid > liquid > air. Kinda funny that we do most of our talking through air.

Consumers differ from producers in that unlike producers, consumers .b. cannot make their own food.
Producers can make their own food and energy, but consumers are different. Living things that have to hunt, gather and eat their food are called consumers. Consumers have to eat to gain energy or they will die. There are four types of consumers:
omnivores, carnivores, herbivoresdecomposers.How do consumers differ from producers?The producers generate food for themselves and others; consumers do not produce anything, instead eating producers, other consumers or both. Organisms that eat only producers (i.e., plants) are called herbivores. Animals that eat only consumers (i.e., meat) are called carnivores.

DQ19: A pea plant must have exactly one of each of the following pairs of traits: Short (s) or tall (t); round (r) or wrinkled (w) seeds; yellow (y) or green (g) peas; and white (wh) or purple (p) flowers. For example, a pea plant can be short with wrinkled seeds, green peas and white flowers. How many different classifications of pea plants are possible
Answer:
There are 16 possible different classifications of pea plants.
Explanation:
In order to get the number of classifications, you must multiply all the possibilities by each other in each trait. This is, each trait has two states (short or tall, round or wrinkled, yellow or green, white or purple) and are referred to as "pair of traits". These must be multiplied with the other pairs of traits. So, the number of different classifications of pea plants is:
the number of high states x number of shape states x number of peas color sates x number of flower color states = 2 x 2 x 2 x 2 = 16.
Blood plays an important role in thermoregulation. Which of the following statements
about thermoregulation is NOT correct
A. Thermoregulation involves a balance between the production of heat and
the loss of heat.
B. The rate of heat loss is affected by the difference between temperature
of skin and external environment.
C. Internal conditions remain the same regardless of the external
conditions.
D. Heat loss from surface of the body is slower when the temperature
difference is higher.
E. Heat loss from the body deceases as more blood passes through the
skin.
Answer: C and E options not correct.
Explanation:
Thermoregulation itself is actually a branch of homeostasis. Homeostasis is defined as the internal regulation of body environment which includes the vital organs of the body such as the heart, liver, brain and contraction of skeletal muscles.
However, there are four routes of heat lost in the body. They are through convection, conduction, radiation, and evaporation. If skin temperature is greater than that of the surroundings, the body can lose heat by radiation and conduction. But, if the temperature of the surroundings is greater than that of the skin, the body actually gains heat by radiation and conduction. In such conditions, the only means by which the body can rid itself of heat is by evaporation. So, when the surrounding temperature is higher than the skin temperature, anything that prevents adequate evaporation will cause the internal body temperature to rise. Even during sports activities, evaporation becomes the main avenue of heat loss. Humidity itself, affects thermoregulation by limiting sweat evaporation and thus heat loss.
When fewer visual pigment molecules are available to absorb light (for example, when a person has a color weakness), which of the following nervous system responses occurs? A.Fewer signals of the weakly perceived color are sent to the brain. B.A normal number of signals of the weakly perceived color is sent to the brain, but each signal is less intense. C.The signals for the weakly perceived color are sent to the brain via other, more plentiful, pigments. D.Light molecules stimulate the cells to make additional pigment.
Answer:
A.Fewer signals of the weakly perceived color are sent to the brain.
Explanation: the brain is the seat of nervous coordination where nerve cells sends signals for processing. An individual with a weak color means a fewer signal for color production is sent to the brain this is due to low pigment it had hence fewer pigment molecule are available to absorb light. If the pigment is high the signal sent will also be high.

Determine whether each characteristic describes a nonvascular plant or a vascular plant.
are small when fully grown
are always seedless
can be large when fully grown
normally live in moist environments
may have seeds
can live farther from water
Answer:
Vascular plants:
Can be large when fully grown.
May have seeds.
Can live farther from water.
Nonvascular plants:
Are small when fully grown.
Are always seedless.
Normally live in moist environments.
Explanation:
Plants can be classified regarding their flowering and their vasculature. When taking vasculature into consideration, they can be classified as Vascular Plants or Nonvascular plants.
Vascular plants have separate tubular tissues that are used to transport food and water, while nonvascular plants do not have these tissues. For this reason, nonvascular plants have a much harder time controlling the water inside them, and that's why they need to live in humid environments in order to survive. Vascular plants, on the other hand, can live in places farther from water.
Since they do not have vasculature, nonvascular plants are short in length, which makes it easier to survive considering the lack of tubular structures made for transport that vascular plants have.
Nonvascular plants do not have a vasculature, which means they do not have roots, stems, leaves nor seeds.

Which type of inheritance best explains the child’s hair type?
A
codominance because the child’s hair type is a blend of the parental hair types
B
codominance because both the male and the female carry the gene for hair type
C
incomplete dominance because the child’s hair type is a blend of the parental hair types
D
incomplete dominance because both the male and the female carry the gene for hair type
Odpowiedź:
A) codominance because the child’s hair type is a blend of the parental hair types.
Wyjaśnienie:
AA - curly hair
aa - straight hair
Aa - qualities AA + qualities aa = Wavy hair
The type of inheritance that best explains the child’s hair type is codominance because the child’s hair type is a blend of the parental hair types. The correct option is A.
What is inheritance?Inheritance is the transfer of genes and characteristics from the parent generation to the offspring. It is done in sexual reproduction. The traits of the mother and the father are transferred into the child.
Codominance is a type of inheritance in which the traits of the father and the mother get blended and a third different type of trait is shown in the offspring.
Here, the father has straight hair, and the mother has wavy hair, but the male child shows the hair is wavy hair. This shows the process of codominance in the child.
AA - curly hair
aa - straight hair
Aa - qualities AA + qualities aa = Wavy hair.
Thus, the correct option is A. codominance because the child’s hair type is a blend of the parental hair types.
