Answer:
is the site where lipids destined for other cellular compartments are manufactured.
Explanation:
This is because smooth endoplasmic recticulum is an organelles found in eukaryotic organisms that lack membrane bound ribosomes and are found in cells that has much lipids like ovaries, testes, oil glands in the skin e.t.c. They are important in the synthesis of lipids is the site where lipids , Phospholipids, steroid hormones.
They also play a major role in detoxification of harmful metabolic by products and metabolic processes of calcium ions within the cell

A set of 23 chromosomes in a human cell
contains 3.2 billion pairs of DNA bases in
sequence. On average, about how many pairs
of bases are in each chromosome?
Explanation:
The human genome contains approximately 3 billion of these base pairs, which reside in the 23 pairs of chromosomes within the nucleus of all our cells. Each chromosome contains hundreds to thousands of genes, which carry the instructions for making proteins.The human genome contains approximately 3 billion of these base pairs, which reside in the 23 pairs of chromosomes within the nucleus of all our cells. Each chromosome contains hundreds to thousands of genes, which carry the instructions for making proteins.
What is chromosome ?
A chromosome is a thread-like structure present in the nucleus of cells such as plant, animal and human cells and it is made of a molecule of DNA (Deoxyribonucleic acid) and histone proteins.
It is composed of three components, DNA, proteins and RNA, amount of the DNA content ranges from 30 to 40 %, the amount of proteins from 50 to 65%, and small amount of RNA from 1 to 10%.
Two types of protein present in DNA such as histone and non-histones proteins, histone constitute large amount (90% of total protein), whereas non-histone is present in small amount (around 10% of total protein).
The histone protein is basic, whereas, the DNA is acidic, so it can be neutralized; DNA in chromosome is present in two forms such as Euchromatin and Heterochromatin.

Action Potential: Relative refractory period
In a neuron, there is a period of time called the absolute refractory period where it is impossible for an action potential to
begin. This corresponds to the change in membrane potential from +30 to -70 mV, or the repolarization phase. Towards the
end of the repolarizing phase, there is a relative refractory period where it is difficult, but not impossible, for another action
potential to begin. Using the time slider function, which of the following segments in the neuron would correspond to a
relative refractory period?
A second action potential can be triggered during the relative refractory phase, but it will need a stronger stimulus to do so than the first time. Refractory times are brought on by the inactivation gate of the Na+ channel.
What Action Potential related to Relative refractory period?The axon has a tougher time producing successive action potentials during this time period, which is referred to as the refractory period, as a result of these transient alterations.
As a result, the refractory period restricts the quantity of action potentials that a certain nerve cell can generate in a given amount of action potentials time.
If enough powerful stimuli are applied to the neuron after the absolute refractory time, Na+ channels start to recover from inactivation and the neuron may respond once again by generating action potentials.
Therefore, A stimulus that is stronger than usual is required to generate neuronal activation during the relative refractory period.

Paleoclimatic analysis has generated a claim that there is a possible correlation between an extinction event around 29 million years ago that allowed grasslands to become abundant and the adaptive radiation of several groups of butterflies.
Which of the following proposes the best alternative hypothesis for the claim?
A- Climate analysis conducted by sampling pollen preserved in amber shows an increase in grass pollen 29 million years ago, but there is no significant difference between speciation rate, as well as species richness with regard to butterflies, before and after 29 million years ago.
B- Climate analysis conducted by sampling pollen preserved in amber shows an increase in grass pollen 29 million years ago, which indicates there was an increase in grasslands that correlates to an increase in butterfly speciation during the same time period.
C- There is a correlation between the rapid and wide-ranging decrease in species richness of insects in general 29 million years ago and the increase in species richness and diversity among the butterfly population during the same time period.
D- Evidence of rapid speciation among butterfly species 29 million years ago is evenly distributed among all environments of that period.

In this phase the sister chromatids line up on the _______ plate through a push and pull motion as they connect to the microtubule spindle fibers emanating from the ________. The third phase of Mitosis is________ . In this phase the________ (sister chromatids or homologous chromosomes) are pulled apart. The fourth phase of Mitosis is_______ . In this phase the nuclear ________starts to reform and the DNA de-condenses.
MITOSIS:
This question is describing the process of mitosis, a kind of cell division that results in two genetically identical daughter cells. Mitosis consists of four stages namely: prophase, metaphase, anaphase, and telophase etc. PROPHASE is the first stage of mitosis where DNA condenses down into CHROMOSOMES, and the duplicated separate.METAPHASE is characterized by the lining up of sister chromatids at the CELL PLATE through a push and pull motion as they connect to the microtubule spindle fibers emanating from the CENTROSOME. ANAPHASE is the third stage of mitosis in which duplicated chromosome/sister chromatids are pulled apart into opposite poles. The fourth stage is TELOPHASE where the NUCLEAR MEMBRANE starts to reform and the DNA de-condenses.Learn more at: https://brainly.com/question/3327479?referrer=searchResults
