Plants absorb the sun's energy. The plants are then eaten by animals and absorbed by animals. ... Name two ways in which the Earth system relies on energy from the sun? Plants use solar energy as their power source and energy reflected by Earth's surface warms the Earth's atmosphere creating winds.

Answer: The answers seem correct.

1. Active transport - the process in which energy is used to move the particles of a substance against a concentration gradient from a region where they are in lower concentration to a region whey are in higher concentration.

2. The answer chosen for #2 makes sense because energy is usually needed when you putting effort into doing an activity that includes some type of force. That means ions are using energy to be moved against the concentration gradient.

3. Volume makes sense for the last question since the cells are using a space (volume) to move material in and out by diffusion. The other options besides volume are unreasonable.

Tallness ( T) is dominant to dwarfness (t), while red (R) flower color is dominant to white (r). The heterozygous condition resu
Tju [1.3M]

Answer:

All the offspring have genotype RrTt

Phenotype is Pink and tall snapdragon

Explanation:

Given

Tallness ( T) is dominant to dwarfness (t)

Red (R) flower color is dominant to white (r)

It is given that heterozygous condition results in pink (Rr) flower color which means that the allels for color of flower show co dominance

Genotype of dwarf red snapdragon is RRtt

Genotype of a plant homozygous for tallness and white flowers is rrTT

The punnet square representing the cross between RRtt and rrTT is as given below-

Rt     Rt         Rt     Rt

rT RrTt      RrTt RrTt    RrTt

rT RrTt      RrTt RrTt    RrTt

rT RrTt      RrTt RrTt    RrTt

rT RrTt      RrTt RrTt    RrTt  

Thus all the offspring have genotype RrTt

Phenotype is Pink and tall snapdragon

What three distinct elements make up the cytoskeleton in eukaryotic cells?
natita [175]

Answer:

Microfilaments, Intermediate filaments and microtubules

Explanation:

Three distinct elements make up the cytoskeleton in eukaryotic cells are:

1. Microfilaments or actin filaments which are composed of actin proteins. The functions of those filaments are: muscle contraction (myosin heads move “walk” on actin filaments), the movement of the cell,  intracellular transport, maintaince of the cell shape..

2. Intermediate filaments which can be made of vimentins, keratin, lamin, desmin… Their functions are: the maintenance of cell shape, anchoring organelles, structural components of the nuclear lamina, cell-cell and cell-matrix junctions…

3. Microtubules are filaments polymers of alpha and beta tubulin. Their roles are in intracellular transport (associated with motor protein dyneins and kinesins),  formation of the axoneme of cilia and flagella, formation of the mitotic spindle.

Why is it beneficial for female peacocks to choose to mate with a male peacock with a full colorful trains?
vesna_86 [32]

Answer:

Peahens often choose males for the quality of their trains -- the quantity, size, and distribution of the colorful eyespots. Experiments show that offspring of males with more eyespots are bigger at birth and better at surviving in the wild than offspring of birds with fewer eyespots.
