During a schoolyard survey, students observe a litter of baby rabbits with brown and white offspring. Explain how it is possible for two brown furred rabbits to have a white furred offspring. Use evidence to support your answer.
help asap
Answer:
Its a recessive gene
Explanation:
It was passed down by their grandparents, or great grandparents
The two brown furred rabbits can produce white furred offspring if both parent stocks are heterogenous brown rabbits (Bb x Bb).
[tex]\frac{1}{4}[/tex] or 25% of the offspring will be white furred (bb) as shown in cross done with a Punnett Square (see attachment below for evidence).Recall:
A recessive trait will be expressed in an offspring if two copies of the recessive genes for a trait are present in the offspring.Let's assume the gene for brown fur is dominant over the gene for white fur.
Using B to represent gene for brown furb to present gene for white furTherefore, the two brown furred rabbits can produce white furred offspring if both parent stocks are heterogenous brown rabbits (Bb x Bb).
[tex]\frac{1}{4}[/tex] or 25% of the offspring will be white furred (bb) as shown in cross done with a Punnett Square (see attachment below for evidence).

The approximate date of the next full moon is to be considered as the July 23.
Calculation of the approximate date of the next full moon:Since two students want to go on a night hike so there should be full moon in July.
So if there is any third quarter moon on July 2
So here the date should be July 23 since it takes 21 days for the third quarter moon to get to a full moon.

Which group of plants lacks true roots, stems, and leaves?
A seedless vascular plants
B nonvascular plants
C nonflowering seed plants
D flowering plants
This quetion is from edgenutiy
The nonvascular plants are the group of plants that lacks true roots, stems, and leaves. The correct option is B.
What are non-vascular plants?Plants lacking a circulatory system made up of xylem and phloem are referred to as non-vascular plants.
They may instead have more basic tissues with tailored capabilities for the internal transfer of water.
Mosses, hornworts, and liverworts are examples of nonvascular plants. They don't have leaves, stems, or roots.
Nonvascular plants require a damp environment, are low-growing, and reproduce using spores.
The primary distinction between vascular and nonvascular plants is that the former have a vascular system for the transportation of food and water, whilst the latter lack circulatory tissues.
The majority of liverworts are quite rare in the park and need to be close to water to survive. Mosses and liverworts are tiny, non-vascular, primitive plants.
Thus, the correct option is B.

What is the primary function of this body system?
The brain, together with the neurological system that connects to it, is the most important organ system in the human body, even though your heart is also a key organ.
What is the role of body system?Blood containing oxygen is delivered to your bones via your circulatory system.
Your bones are actively creating new blood cells in the interim. Together, these mechanisms preserve internal equilibrium and stability, or “homeostasis.”
The body's action and functionality are controlled by the neurological and endocrine systems.
The respiratory, circulatory, and digestive systems team up to eliminate waste from the body while simultaneously taking in essential nutrients and substances.
Therefore, connecting and supporting is primary function of body system.

It is generally acknowledged that as human beings age, it becomes more difficult for them to lose weight, or even maintain their current weight. People find they have to eat less and/or exercise more to maintain a healthy weight.
Which is the most likely explanation of why weight loss/maintenance becomes more difficult as people age?
a). As humans age, they becomes less active and use their muscles less; therefore, less chemical energy is converted to thermal energy.
b). As humans age, the process of extracting energy from the food becomes less efficient, so more food is needed to provide the same amount of energy.
c). As humans age, they become injured more often and need to increase the amount of food they eat to make repairs to body tissue.
d). As humans age, the body does not convert chemical to thermal energy, so they do no burn off any calories when exercising.
