Offspring sometimes look like their parents because??
Answer:
They inherit the genes from their parents
Explanation:
Answer: So children look like combinations of their parents because they are. Each parent gives half of their genetic material to their children. The combination makes a unique combination of their parents genes. The scientific study of how traits are passed from parents to children is called 'genetics'.
What do osmosis and diffusion have in common?
A.) Both permit molecules of any kind, whether solute or solvent, to cross the bilayer membrane.
B.) Both require the additional energy provided by an energy carrying molecule, like ATP, to allow molecules to pass through the membrane.
C.) Both processes occur through a semipermeable membrane called a concentration gradient.
D.) Both are the net movement of randomly moving molecules that makes concentration nearly equal on both sides of a bilayer membrane.
Answer:
C.) Both processes occur through a semipermeable membrane called a concentration gradient
Explanation:
A. They only let certain things in and out of the membrane
B. They are passive transportors, meaning they do not use ATP or energy
D. They do not randomly move molecules. The concentrations are not equal. It should be from a high concentration to a low concentration.

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).

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.

How does the surface area-to-volume ratio of a small cell compare to that of a large cell?
I'll mark brainliest pleaseeeeeeeeee
Answer:
SA:V ratio
Explanation:
When an object/cell is very small, it has a large surface area to volume ratio, while a large object/ cell has a small surface area to volume ratio. When a cell grows, its volume increases at a greater rate than its surface area, therefore it's SA: V ratio decreases.

What evidence have you discovered to explain how Mendel’s experiments showed that traits in offspring are inherited?
Answer:PLZ MARK ME THE BRANISET
By examining large sample sizes, Mendel showed that his crosses behaved reproducibly according to the laws of probability, and that the traits were inherited as independent events. Two rules in probability can be used to find the expected proportions of offspring of different traits from different crosses.
To find the probability of two or more independent events occurring together, apply the product rule and multiply the probabilities of the individual events. The use of the word “and” suggests the appropriate application of the product rule. To find the probability of two or more events occurring in combination, apply the sum rule and add their individual probabilities together. The use of the word “or” suggests the appropriate application of the sum rule.

This gardener started with much smaller plants in this park. Over time, the garden has grown into a large display of brilliant flowers. What would you tell the gardener to explain how the plants have grown and flourished so successfully?
This is because
1.they are in the right habitat for those kinds of plants
2.the gardener is taking care of them like watering them and not watering when they are about to die or rarely watering them, and always giving them the right amount of water
3.the placement of the plants helps to, they are given the perfect amount of sun and nutrients from the ground
The photosynthetically active eukaryotes and living organisms that produce food are called plants.
The reasons which tell about how plants have grown are:
The planted plants are suitable for the area and are best to be grown in that habitat. They are acclimatized to the soil and can grow in that area due to conditions favourable to them.The factors like watering the right amount and proper sunlight are the reasons that help the plant to grow. The use of nutrients and the soil quality helps the plant to grow fast and flourish well.To learn more about plantation follow the link:
