Force-velocity: how does the speed of the movement change with the load?

Biology

neonofarm [45]3 years ago

Answer:

The Force vs Speed F-V, relationship assumes that at a given velocity, the muscles (load) are generating the maximum force possible.

Explanation:

This is because, as the external load (i.e. mass) increases, the maximal velocity that such load achieves decreases. The load-velocity relationship assumes that the movement velocity is the maximum possible for the given load.

What is the result of a mutation during meiosis?

galina1969 [7]

Answer:

A mutation is a change in the nucleotide sequence of the DNA in a cell. ... Mutations can occur before, during, and after mitosis and meiosis. If a mutation occurs in cells that will make gametes by meiosis or during meiosis itself, it can be passed on to offspring and contribute to the genetic variability of the population.

The directions for each amino acid in a polypeptide are indicated by a codon that consists of ________ nucleotide(s) in an RNA m

ipn [44]

Answer:

3 nucleotides in an RNA molecule.

Explanation:

Protein synthesis in the cell produced by RIBOSOMES requires a lot of energy and it's has the highest mass in living organisms. Protein synthesis involve the process where Messenger RNA (MRNA) message is converted to a polypeptide product. The transcription in the cell produced messenger RNA. The translation of mRNA template converts nucleotide-based genetic information into a protein product. The protein sequences contain about 20 Ami o acids and each amino acids is defined by three nucleotides sequence which is called triplet codon. The relationship between nucleotides codon And amino acids is called genetic code

After phosphates and nitrates have entered a water

frosja888 [35]

After phosphates and nitrates enter a water system, the steps of eutrophication include the rapid growth of algae, death of underwater plant species, depletion of oxygen in the water, and the death of fishes and invertebrates. The correct option would be B.

Eutrophication refers to the excessive enrichment of water bodies by nutrients such as phosphates and nitrates thereby facilitating the rapid growth of some aquatic species with negative effects.

Once a water body becomes excessively enriched with phosphates and nitrates, the following is a sequence of events that follows:

Algal bloom: the nutrients facilitate the rapid growth of algae
The bloom of algal species results in the death of underwater plants as a result of inadequate light.
The death of the underwater plants and the accompanying microbial activities in decomposing them cause oxygen levels in the water to drop.
Reduction in oxygen level causes fishes and other water invertebrates to die due to hypoxia

Therefore, the correct steps of eutrophication according to the illustration is IV, II, I, and III.

Number the following steps for the reproductive system of a self pollinating flowering plant in order from 1 to 5. Use the parts

Leviafan [203]

Answer:

3 Pollen tube forms and grows through the style

5 Sperm fertilizes the egg

1 Pollen is released from the anther

4 The pollen tube reaches the ovule within the ovary

2 Pollen sticks to the stigma

Explanation:

The process of double fertilization entails the fertilization of the egg by one sperm and that of two polar nuclei to produce the triploid endosperm tissue that nourishes embryo.

* The image describes the process in detail.
