Organisms in an ecosystem are interdependent. do you think humans have interdependent relationships with other organisms? explai
jeka94

Humans have an interdependent relationship with other organisms just like organisms in an ecosystem are interdependent.

<h3>How are organisms interdependent?</h3>

To be interdependent means that the involved parties are mutually dependent i.e. they are reliant on one another.

Living organisms in their natural habitat are dependent on one another for food, space, mate and other resources.

However, humans are also interdependent on other organisms for resources like food, raw materials. For example, we eat plant and flesh derived from other organisms.

How does waste move from kidneys to the bladder in the human excretory system?
Salsk061 [2.6K]

The kidneys filter the blood to remove wastes and produce urine. The ureters, urinary bladder, and urethra together form the urinary tract, which acts as a plumbing system to drain urine from the kidneys, store it, and then release it during urination.

Drag the numbers to put the following steps in the correct order.
deff fn [24]

Answer:

- In glycolysis, glucose is split into two pyruvate and makes some ATP

- The Krebs cycle produces ATP, NADH and CO2

- NADH gives electrons to the ETC

- As electrons move down the ETC, a H+ gradient is made

- H+ pass through the ATP synthase to make ATP

Explanation:

This question is describing the processes involved in cellular respiration. Cellular respiration is the way through which living cells synthesize energy (ATP) by breaking down sugar. Cellular respiration involves three major steps: glycolysis, Krebs cycle, and oxidative phosphorylation (electron transport chain).

- Glycolysis is the process whereby glucose is broken down into pyruvic acid or pyruvate with the synthesis of net 2 ATP molecules.

- Kreb's cycle produces ATP, NADH and CO2.

- NADH is an electron carrier that donates electrons to the Electron transport chain (ETC).

- Electrons move down the ETC to produce a proton (H+) gradient

- The proton (H+) passes through an enzyme called ATP synthase to make ATP from ADP molecule.

The A159E mutation causes an A amino acid to be replaced with an E amino acid (their structures are shown here). What type of mu
valentinak56 [21]

Answer:

Substitution

Explanation:

Mutations can simply be defined as change in the structure of a gene. Mutation can be of different types. These include, but not limited to:

  • Insertion: This involves the insertion of extra base pairs into a DNA
  • Deletion: Loss of DNA section
  • Substitution: When a nucleotide base gets substituted with another base.

<em>Substitution of a base can lead to coding of different amino acid and hence, protein. It can also lead to coding of the same amino acid, otherwise known as silent mutation. Base substitution can also lead to the amino-acid-coding codon becoming a stop codon, leading to an incomplete protein.</em>

The correct answer is substitution.
