The alleles for eye color in fruit flies involves one allele that might contain the sequence CCAT. Assume that this allele produces red eyes in a fruit fly, because the allele produces a protein that makes red pigment. Assume that another allele of this gene has a slightly different sequence in the middle: CAAT, instead of CCAT.Which of the statements below is true about the alleles for eye color in fruit flies? Which of the statements below is true about the alleles for eye color in fruit flies? A) The alleles for eye color produce the same phenotype. B) The small change in the DNA sequence causes the allele to produce a different protein, resulting in the production of white eyes instead of red eyes in the fruit fly.

Which example illustrates commensalism and NOT mutualism? A) Hippo dung is eaten by a large species of catfish native to African lakes. The catfish typically follow the hippo herds.

B) Cattle have protozoa living in their gut that digest cellulose. The cows are able to feed on grass, while the protozoa are sheltered inside the cow.

C) Oxpeckers remove parasitic fly larvae from the skin of buffalo. In exchange, they are protected from predatory cats, who will not challenge a buffalo.

D) Ants 'farm' aphid insects like cattle. Aphids suck the sap out of trees, which ants also feed on. In turn, the ants sting predators that attack the aphids.

Answers

It is answer A, the hippo is not benefitting from the catfish, therefore it is not mutualism.


the answer is A hope it helped.

The motion of objects can be quite complex. The motion of this frog is an example, Suppose that the frog moves from one lily pad to the other in 1 second 1 m Describe the motion of the frog as it makes one round trip between the two lily pads Use the terms speed, velocity, displacement, and distance in your answer​

Answers

The speed of the frog is understood to be 1m/sec.and the velocity is that through which a frog can turn and jump in a different direction in 1 sec the distance is 1 m. This returning back to the original position represents no displacement.

What is Displacement?

Displacement may be defined as the rate of change in the position of an object. It is a vector quantity and has a direction and magnitude. It is represented as an arrow that points from the starting position to the final position.

Velocity is a vector expression of the displacement that an object or particle undergoes with respect to time. The standard unit of velocity magnitude (also known as speed ) is the meter per second (m/s).

Speed may be defined as the rate of change of position of an object in any direction. It is measured as the ratio of distance to the time in which the distance was covered. It is a scalar quantity as it has only direction and no magnitude.

Why forest hold great important for prevalence of sustainable development​

Answers

Answer:

Forests hold great importance for the prevalence of sustainable development due to several reasons:

1. Biodiversity: Forests are home to a wide variety of plant and animal species, making them crucial for maintaining biodiversity. Biodiversity is essential for ecosystem stability, as different species play unique roles in ecological processes such as pollination, nutrient cycling, and pest control. Preserving forests helps protect these species and their habitats, ensuring the long-term health and resilience of ecosystems.

2. Carbon Sequestration: Forests act as carbon sinks by absorbing and storing carbon dioxide from the atmosphere through the process of photosynthesis. This helps mitigate climate change by reducing the concentration of greenhouse gases in the atmosphere. Forest conservation and reforestation efforts play a vital role in climate change mitigation strategies, helping to stabilize global temperatures and prevent further environmental degradation.

3. Water Regulation: Forests play a crucial role in regulating the water cycle. Trees absorb water from the soil and release it back into the atmosphere through a process called transpiration. This helps maintain moisture levels and regulate rainfall patterns. Forests also act as natural filters, preventing soil erosion and filtering pollutants, thus improving water quality in rivers and streams. Access to clean water is essential for sustainable development, and forests play a critical role in maintaining water resources.

4. Socioeconomic Benefits: Forests provide numerous socioeconomic benefits to local communities and economies. They serve as a source of timber, non-timber forest products, and medicinal plants, supporting livelihoods and economic development. Forests also attract tourism, generating revenue and employment opportunities. By promoting sustainable forest management practices, communities can derive benefits from forests while ensuring their long-term conservation.

5. Cultural and Spiritual Value: Forests have cultural and spiritual significance for many communities around the world. They are often regarded as sacred spaces and play a vital role in cultural practices, traditional knowledge, and spiritual beliefs. Preserving forests helps safeguard these cultural heritage values, fostering a sense of identity and connection to the land.

Explanation: so in summary due to their role in maintaining biodiversity, carbon sequestration, water regulation, providing socioeconomic benefits, and cultural significance. Protecting and managing forests sustainably is essential to ensure a balance between human needs and environmental conservation, promoting a more sustainable and resilient future for generations to come.

Each tip (sp 1-4) represents a different species of ant. Species 1 is the outgroup. Of species 3 and 4 possessed a Thymine a nucleotide position 45, while species 1, and 2 possessed an Adenine, then what kind of character is the A nucleotide at position 45?A. Convergent.B. Homoplasious.C. Derived.D. Ancestral.

Answers

In this case, the type of character is the A nucleotide at position 45 is - C. Derived.

The derived characters or traits are that arose in the most recent common ancestor and passed on the lineage. It can be referred to as traits that are not present in older ancestors but in recent lineage.

  • in this case, the presence of nucleotide at position 45 in species 1, and 2 are shows ancestor character as it is not present in Of species 3 and 4 possessed a Thymine a nucleotide position 45 are derived.
  • Convergent evolution occurs when the trait is evolved independently in two groups, which is not present here.
  • Homoplasoius traits are those which are not found in the common ancestor also incorrect as it is not the case here.

Thus, the type of character is the A nucleotide at position 45 is - C. Derived.

Answer:

C. Derived

Explanation:

Derived kind of character is the A nucleotide at position 45.

Derived character:  Derived kind of character is one that evolved in the lineage and  leading up to a clade and that sets members of that clade apart from other individuals

Example of a derived character:  the loss of a tail, a trait that first appeared in an ancestor of apes and man.

Why do we need to destarch a plant

Answers

in photosynthesis experiment, the effect of the light will be observe during the starch production- thus you need to have a plant without a starch to observe if the starch is produced during photosynthesis. Letting the leaves of the plant deprived from light for 48 hours will be forced to use its reserved starch making the storage of the starch decrease.
