Cell membrane i think as I remember
Explanation:
Cuando los niveles de testosterona están bajos, la hormona liberadora de gonadotrofina (GnRH) es liberada por el hipotálamo que a su vez estimula la glándula pituitaria para liberar LH. Esta última hormona estimula los testículos para sintetizar la testosterona.
An ecosystem is a self supporting system in which there is a flow of materials and energy.
<h3>What is an ecosystem?</h3>
An ecosystem is a self supporting system in which there is a flow of materials and energy.
Let us now see the role of each organism in the small ecosystem.
- flower - producer
- butterfly - primary consumer
- bird - secondary consumer
- earthworm - decomposer

Answer:
<u><em>The correct options are:</em></u>
<u><em>All traits are inherited.</em></u>
<u><em>Offspring inherit one allele for a gene from each parent.</em></u>
<u><em>An offspring with two identical alleles for a trait is homozygous.</em></u>
Explanation:
- In the biological world, a trait can be described as a genetic characteristic which makes up an organism. Every organism has a particular set of traits.
- Traits are inherited from parents, however they can be influenced by the environment.
- The alleles of a gene make up the genotype and the influencing phenotype. An organism acquires one allele for the gene pair from each parent.
- When both the alleles of a gene pair are similar, the organism is said to be homozygous for the trait. If both the alleles of a gene pair are different, the organism is said to be heterozygous for the trait.
Water and sodium ions are reabsorbed in the proximal tubule in a relationship that results in a decrease in tubular fluid volume that is isotonic to plasma.
<h3>What do you mean by Proximal tubule?</h3>
A Proximal tubule may be defined as the portion of the nephron that lies in between Bowman's capsule and the loop of Henle.
The major function of the proximal tubule is to reabsorption of sugar, sodium, chloride ions, and water from the glomerular filtrate. It decreases the volume of tubular fluid.
Therefore, water and sodium ions are reabsorbed in the proximal tubule in a relationship that results in a decrease in tubular fluid volume that is isotonic to plasma.
