On one cactus species, the red flowers are dominant over white flowers. If you crossed two heterozygous cacti, what would be the probability of having offspring with red flowers?
Answers
Answer:
3/4
Explanation:
This question involves a single gene coding for flower color in cactus plant. The allele for red flowers (R) are dominant over the allele for white flowers (r). This means that a cactus that is heterozygous (Rr) for the Gene will possess a red phenotype.
In this cross, two heterozygous cacti are crossed. The following gametes will be produced by each heterozygous parent: R and r. Using these gametes in a punnet square, the following genotype of offsprings will be produced;
RR, Rr, Rr, and rr
RR, Rr and Rr are Red flowers (3/4)
rr are white flowers (1/4)
Therefore, the probability of having offspring with red flowers is 3/4.

The birds would either go hungry or have to find something else to eat.

How do cells maintain homeostasis without using energy
Answers
Answer:
Form the cell membrane around food to create a vacuole that is kept separate from the rest of the cytoplasm while enzymes break down the food.
Cells maintain homeostasis without using energy by relying on passive transport processes.
Passive transport mechanisms do not require the input of cellular energy (ATP) and instead rely on the inherent kinetic energy of molecules and the concentration gradients of substances.
One common example of passive transport is simple diffusion, where molecules move from an area of higher concentration to an area of lower concentration until equilibrium is reached.
Similarly, facilitated diffusion utilizes protein channels or carriers to facilitate the movement of specific molecules across the cell membrane without energy expenditure.
Osmosis is another passive process where water molecules move across a selectively permeable membrane to balance the concentration of solutes on both sides.
By utilizing these passive mechanisms, cells can maintain a stable internal environment and achieve homeostasis without the need for energy expenditure.

5. What is the response of an ectotherm, such as a lizard, when it encounters cold temperatures?
It will move to a warmer spot.
It will remain in the cold environment.
It will run toward the stimulus.
It will become hungry.
Answers
Answer:
It will move to a warmer spot.
Explanation:
An ectothermic animal, also known as a "cold-blooded" animal, is one that cannot regulate its body temperature, so its body temperature varies depending on the environment.
Many ectotherms live in environments that require little regulation, such as the ocean because the ambient temperature tends to stay the same.
