Answer:
sex cells with 23 chromosomes: 22 autosomes and one sex chromosome.
Explanation:
Sex cells are the gametes and are products of meiosis. These cells have haploid chromosome number. Human sex cells are sperms and egg which serve as male and female gamete respectively. Human sex cells have n = 23 chromosomes. Out of total 23 chromosomes, 22 chromosomes are autosomes while one is the sex chromosome (either X or Y chromosome). Deviation from this pattern can cause any genetic disorder.

The sea otter acts as a keystone species in the kelp (giant seaweed) forests of the ocean in the Pacific Northwest. Sea otters feed on sea urchins, which in turn feed on kelp. Crabs, snails, and geese also depend on kelp for food, and many types of fish use the kelp to hide from predators. Sea otter populations are declining in some areas because of increased predation by orca whales. What effect will the decline in sea otters likely have on the kelp community
Hello~
The decline of otters with cause in increases in the population of sea kelp!

Answer:
Las estructuras y organelas que son exclusivas de las células eucariotas vegetales son: la pared celular, los cloroplastos, las vacuolas y los plastidios. Cada una de estas estructuras tiene distintas funciones.
Explanation:
Las células eucariotas vegetales tienen otro tipo de estructuras y organelas ya que tienen otro tipo de procesos, entre los cuales se encuentra la fotosíntesis.
Funciones:
Pared Celular: protege la membrana plasmática y toda la estructura celular. Tiene plasmodesmos a través de los cuales ingresan sustancias.
Vacuolas: almacenan sales, agua y productos residuales
Plastidios: le dan distintas características a las plantas. Algunos almacenan sustancias, otros definen su color.

An underground water supply has a depth of 200 m of water. Water seeps in at the rate of 4 cm / year . Water is pumped out at the rate of 1m / year . How long will this water supply last? To find the net water loss from an underground water supply, subtract the amount that seeps into the water sup ply from the amount removed from the water supply. How long will the water supply last if water seeps in at the rate of 10 cm / year and is removed at the rate of 10 cm / year ?
Answer:
208 years.
Explanation:
The water supply last for 208 years if the water seeps in at the rate of 4 cm / year and water is pumped out at the rate of 1m / year. The water supply last forever if water seeps in at the rate of 10 cm / year and is removed at the rate of 10 cm / year because the same amount of water enters the underground which can be pumped from the soil. If more water is extracted from the soil as compared to it seeps, so with the passage of time water concentration in the soil decreases and in the last it disappeared.

How will distinguish between natural and artificial fibres by observing the smell produced when burnt?
its not biology it's chemistry
Answer:
Natural fiber smell like paper whereas artificial fiber smells like an acid.
Explanation:
We can distinguish between natural and artificial fibers by observing the smell produced when burnt because both produces different types of smell when burnt. When the artificial fibers are burn, it produces acid or chemical like odor and leaving a plastic like bead while on the other hand, when the natural fiber burn, it produces smell of burning paper or hair and leaving ash of soft and grey colour. Natural organic fibers burn rapidly with a yellow flame.

C. A dicot
D. moss
process of how a seed grows into a plant
Answer: As it takes up more water, the seed expands and the seed coat cracks open. The embryo inside the seed is made up of a small shoot and a small root. The root is the first to emerge from the seed. As it grows, it anchors the plant to the ground, and begins absorbing water through the root.

a population of animals is split in half by a river before speciation is completed the two halves are rejoined when a drought causes the river to run dry how would this impact the two populations
A. speciation would still occur because the two halves would be too different genetically to interbreed.
B. traits that had developed through mutation would still exist only in one of the halves.
C. the two halves would be reproductively isolated.
D. individuals could now freely mate, and gene flow would increase. (this took so long to write please clap)
Answer:
D. Individuals could now freely mate, and gene flow would increase.
Explanation:
Since genes/traits are passed on from parent to offspring the gene flow would definitely increase. Since the population of animals is now brought back together by the drought, they now have more mates resulting in more and different genes combining. Therefore, the gene flow would increase.

The respiratory center rhythmically sends neural output to the diaphragm and ____________ muscles to regulate quiet breathing. The respiratory center is stimulated to alter breathing rate and depth by ____________ input from ____________ in the brain. Additional input comes from peripheral receptors, including ____________ within the carotid and aortic bodies, ____________ of the mucosal lining of the respiratory tract, ____________ of the lungs and visceral pleura, and ____________ of the joints. Breathing can be consciously controlled by the ____________ , which bypasses the respiratory center to directly stimulate lower motor neurons.
Answer:
The respiratory center rhythmically sends neural output to the diaphragm and external intercostal muscles to regulate quiet breathing. The respiratory center is stimulated to alter breathing rate and depth by sensory input from central chemoreceptors in the brain. Additional input comes from peripheral receptors, including chemoreceptors within the carotid and aortic bodies, irritant receptors of the mucosal lining of the respiratory tract, stretch receptors of the lungs and visceral pleura, and proprioceptors of the joints. Breathing can be consciously controlled by the cerebral cortex, which bypasses the respiratory center to directly stimulate lower motor neurons.

Why is it important for a cell to be able to turn a gene off?
Answer:
Gene regulation is an important part of normal development. Genes are turned on and off in different patterns during development to make a brain cell look and act different from a liver cell or a muscle cell, for example. Gene regulation also allows cells to react quickly to changes in their environments.

What would happen if the American bullfrog went extinct? NO LINKS!!!!!!!!!!!!!!!!!!
Answer: The death of frogs would send a ripple through the ecosystem. The number of animals that eat the frogs will die off, then the animals that eat them will go hungry, and their populations will be devastated as well. This would just keep going up the food chain
Explanation:
Invasive bullfrogs upset the balance of predator-prey interactions and competition for food and shelter, but they also may be worsening another ecological disaster in the amphibian world. ... The invasive American Bullfrog can act as a vector, harboring this fungus, with no ill effects, and spread it to other amphibians

When limiting factors exhibit pressure on a population, what happens to the growth graph?
Answer:
Anything that limits carrying capacity = exhibits pressure on a population
These include:
- food resources
- shelter
- population density (space)
- predation
What happens to the growth graph is that it starts leveling off and not growing at as fast of a rate. It fluctuates around the carrying capacity, k. Look at a logistic population model for more info, and your growth graph will resemble exactly that
