lina2011 [118]2 years ago
5 0

Answer:

A gene mutation is an alteration of the nucleotide sequence of a gene. Gene mutations can be caused by errors in DNA replication during cell division by both mitosis and meiosis. In addition, gene mutations are caused by environmental factors such as UV and chemicals. These factors are called mutagens.

A Cotton shirt takes more time to dry as compared to a synthetic shirt. Why?<br><br>​
Salsk061 [2.6K]

Answer:

Due to absorption of more water.

Explanation:

A Cotton shirt takes more time to dry as compared to a synthetic shirt due to absorption of more water by the cotton fiber as compare to other fiber. Cotton absorbs much more water than other synthetic fibers, and attached to the molecules of cotton for longer period of time which means cotton fibers take more time to dry as compared to synthetic fiber which absorb little amount of water and loosely attached to the molecules of fiber.

Marianna [84]

Answer:

A. Oedema and ion imbalance

Explanation:

The proximal tubule is very important to the maintenance of homeostasis in the renal microenvironment. The alterations of the physiological functions will therefore distort the reabsorption of other ions. The blockage of sodium reabsorption into the channel will leads to an hypotonic internal environment. This will afterward leads to reduction of the reabsorption of water into the organ and increase the reabsorption of other ions into it. This will have clinical effect on the organism. Which is oedema of the extracellular surrounding of the tubules through accumulation of fluids and could lead to imbalance in neurological sense due to the imbalance in other ions.

Secondary succession could occur after a _______.
pychu [463]

Answer:

disturbance has destroyed population in a community

Explanation:

The secondary succession occurs after there has been some disturbance that has manged to badly damage or destroy the populations in a community. This basically means that after some catastrophic event that happened to a certain population or populations, other species moved in to colonize the freed space. There are countless examples of secondary succession in nature, and one of the best is when there is a strong volcanic eruption. The volcano manages to destroy the population of plants and animals in its close surroundings, but after the eruption ends, the space starts to be colonized by new plants and animals step by step until they create a new well functioning community.

Llana [10]

Answer:

The dominant phenotypes are Long flagella and one vacuole, and the recessive phenotypes are small flagella and two vacuoles.

Explanation:

As you can see in the attached table

1. For the size of the flagella we gave that:

- 241 organisms have long flagella

- 79 organisms have short flagella,

As there are more organisms with long flagella we can conclude that this is the dominant phenotype while the short flagella is the recessive phenotype.

2. For the number of vacuole we have:

- 247 organisms have one vacuole

- 73 organisms have two vacuole

As there are more organisms with one vacuole we can conclude that this is the dominant phenotype while having two vacuoles a is the recessive phenotype.

Then

Dominant phenotypes = Long flagella and one vacuole

Recessive phenotypes = Short flagella and two vacuoles
