What makes mitochondrial DNA useful as a molecular clock? (2 points)
It is only found in select organisms, making it easier to compare relationships between species that have it.
A large portion of the DNA ring is not vital to structure or function, allowing it to accumulate neutral mutations.
Its rate of mutation increases over time as organisms continue to evolve and differentiate from each other.
A slow mutation rate makes it useful for determining evolutionary relationships between ancient species.

Answer:
Mitochondrial DNA is useful as a molecular clock because it displays uniparental inheritance

The diagrams show what happens to the shape of a plant cell place in distilled water. Explain why the cell swells and becomes turgid. Name the process involved.
Answers
Answer:
the name of the process should be osmosis
Explanation: Reason being that plant cells are hypertonic because they have a cell sap so when they are pout in distilled water which is a hypotonic solution, it then absorbs water by osmosis and swells up and become turgid. But they do not burst because they have a cell wall that develops a wall pressure that balances the turgor pressure exerted by turgid cells

Here's a visual to to the changes in temperature as altitude increases:
how many layers are in earth atmosphere ?
The Earth’s atmosphere is layered and each layer of the atmosphere has its own specific traits. The atmosphere of Earth is divided into four layers as Troposphere, Stratosphere, Mesosphere and Thermosphere
Generally, temperatures decrease with increasing height because the atmosphere distributes itself according to gravity. In the troposphere, the temperature generally decreases with altitude. The reason is the troposphere's gases absorb very little of the incoming solar radiation.
Troposphere - temperature decreases with altitude
Mesosphere - temperature decreases with altitude
The temperature increases with increasing altitude in the stratosphere because there’s a high concentration of ozone molecules.
Stratosphere - temperature increases with altitude
Thermosphere - temperature increases with altitude

A baker activates yeast cells with hot water, and adds sugar as their source of food. As the yeast begin their metabolic processes, the bowl it is in is covered with plastic so that no oxygen can get to them. At this point, the yeast will __ *
1 point
a. produce far more ATP than is necessary in response to the lack of oxygen
b. continue to go through aerobic respiration if enough sugar is present
c. die since all living organisms need oxygen to survive.
d. perform anaerobic respiration in the absence of oxygen
Answers
Answer:
The correct answer would be - option D. perform anaerobic respiration in the absence of oxygen.
Explanation:
Yeast is a facultative anaerobic single-cell organism that can live without oxygen. If yeast cells did not get the oxygen they use anaerobic respiration to get the energy.
If the baker activates these cells and stops them to get oxygen the yeast cells have to switch to anaerobic respiration to survive and produces ethanol and releases carbon dioxide.

ribosome ->lysosome -> ER -> released
Answers
Answer:
ribosome -> ER -> Golgi -> released
Explanation:
Ribosomes are where proteins are created, ribosomes are located on the rough endoplasmic reticulum (RER). From the ER, proteins will be transported to the Golgi Complex for packaging, transport, and release. The answers with lysosome can be ignored because lysosomes break down waste materials of the cell. Therefore the answer is ribosome -> ER -> Golgi -> released.

1. Flowers must rely on vectors to move pollen. These vectors can include wind, water, birds, insects, butterflies, bats, and other animals that visit flowers. We call animals or insects that transfer pollen from plant to plant “pollinators”.
2. Germination:When a seed falls on the ground, it needs warmth and water in order to germinate; some seeds also need light. Dicots have seed coats that soften with moisture. After being planted in the soil for a few days, the seed absorbs water and swells until the seed coat splits.
The botanist wanted to produce a generation of snapdragons that all had pink flowers.
State the phenotypes of the parent plants that the botanist would need to cross.
Explain your answer.
Answers
Answer:
He would need to cross one homzygous red (RR) and homzygous white (rr)
Explanation:
Flower color in snapdragons is controlled by a gene whose alleles exhibits incomplete dominance. The allele for red coloration (R) is incompletely dominant over the allele for white coloration (r). The intermediate phenotype that is produced in an heterozygous state (Rr) is PINK.
According to this question, a botanist wanted to produce a generation of snapdragons that all had pink flowers (Rr). This means that in order to do this, the botanist would need to cross a red snapdragon plant (RR) and a white snapdragon plant (rr) to produce an 100% Pink (Rr) snapdragon in the F1 generation.

Point mutation is a kind of mutation that involves a single nucleotide base. Generally, mutation is any alteration that occurs to the genetic sequence of an organism, however, point mutation involves only one base of the numerous in the sequence.
Point mutation can be an insertion, substitution, deletion etc, but it is the gene mutation that would have the smallest impact on a protein's amino acid sequence. This is because the change to the genetic sequence involves a single base.

What is blood?
Answers
Answer:
1. The main physiological role of red blood cells (RBCs), or erythrocytes is to transport of gases (O2, CO2) from the lung to the tissues and to maintain systemic acid/base equilibria. In addition, RBCs are well equipped with antioxidant systems, which essentially contribute to their function and integrity.
2. In humans, it includes plasma (the liquid portion), blood cells (which come in both red and white varieties), and cell fragments called platelets. Plasma is the main component of blood and consists mostly of water, with proteins, ions, nutrients, and wastes mixed in.
3.Blood is a body fluid in humans and other animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells.

“How might an energy requirement affect an individual who has a cancerous tumour?”
Answers
Answer:
Cellular respiration describes the series of steps that cells use to break down sugar and other chemicals to get the energy we need to function. Energy is stored in the bonds of glucose (like a stretched rubber band), and when glucose is broken down, much of that energy is released. Some of it is captured in a form that can be used to do work in cells - a molecule called adenosine triphosphate or ATP. The energy that is not captured in ATP is usually given off as heat (one of the things that helps us maintain our normal body temperature).
