Why don't the hydrolytic enzymes Within lysosomes destroy each other?

Biology
1 answer:
Firdavs [7]2 years ago
8 0

Answer:

A lysosome is a membrane-bound cell organelle that contains digestive enzymes.  They break down excess or worn-out cell parts. They may be used to destroy invading viruses and bacteria. If the cell is damaged beyond repair, lysosomes can help it to self-destruct in a process called programmed cell death, or apoptosis.

To test the quality of water sources in her area, Shameka collects five samples from each water source and tests the quality of
Neporo4naja [7]

Of the steps included in the scientific method, Shameka is performing step five, which is to<u> test your hypothesis by performing an experiment</u>.

The scientific method is the globally accepted process by which to make scientific claims. This method includes seven steps which are:

  1. Ask a question
  2. Do research
  3. Create a hypothesis
  4. Design an experiment to test the hypothesis
  5. Perform the experiment
  6. Study the results and make a conclusion
  7. Communicate the results to your peers.

The question states that Shameka is <u>gathering samples from nearby water sources</u>, therefore she is in the process of testing her hypothesis through experimentation, which corresponds to step 5 of the scientific design.

Black eyes are dominant to orange eyes, and green skin is dominant to white skin. Sam, a MendAlien with black eyes and green ski
Anna [14]
<h2>The correct answer is explained below:</h2>

Explanation:

  • According to the given question,
  • For eye color, let the black color be represented by B allele and orange color be represented by b allele. Black is dominant over orange.
  • For skin color, let the green skin be represented by G allele and white skin be represented by g allele. Green is dominant over white.
  • The phenotype of Sam is black eyes and green skin so his genotype can be BBGG or BbGg. It is also said that one of his parents has phenotype orange eyes and white skin. That parent's genotype must be bbgg.
  • Hence, the genotype of Sam must be BbGg.
  • Carole has the phenotype of orange eyes and white skin. Her genotype would bbgg.
  • The gametes produced by Sam are: BG, Bg, bG, bg.
  • The gametes produced by Carole are: bg.
  • Mating them we get,

           BG                    Bg                   bG                       bg

bg      BbGg               Bbgg               bbGg                   bbgg

  (Black/ Green) (Black/ White) (Orange/Green)  (Orange/ White)

  • The genotypes and phenotypes (Eye color/ Skin color) obtained are represented above.
  • The phenotypes (Eye color/ Skin color) obtained are in the following ratio:

(Black/ Green) : (Black/ White) : (Orange/Green) : (Orange/ White) = 1 : 1 : 1 : 1

Assuming no crossing over between the gene in question and the centromere, during what phase of meiosis do alleles segregate?
choli [55]

Answer:

During Anaphase stage

Explanation:

Meiosis is the type of cell division employed during gamete formation when each resulting gamete (daughter cell) has their chromosomal number reduced by half. Meiosis occurs in a two step division; Meiosis I and II. Meiosis I involves the separation of homologous chromosomes (similar but non-identical chromosomes received from each parent) while Meiosis II involves separation of sister chromatids (replicated chromosomes).

Alleles are present on the chromosomes which segregate or separate during the anaphase stage. Alleles received from each parent are separated in Anaphase I of meiosis I, which the identical replicated alleles are separated in anaphase of meiosis II.

What considerations determine if an animal excretes nitrogenous waste as ammonia, uric acid, or urea
Evgesh-ka [11]
