Answer: gametes
Explanation: During meiosis one cell divides twice to form four daughter cells. These four daughter cells only have half the number of chromosomes of the parent cell – they are haploid. Meiosis produces our cells or gametes (eggs in females and sperm in males)

How is the reproductive rate of marine mammals
related to their status in regards to extinction?
Answer:
The fewer fish the less that can reproduce.
Explanation:
marine mammals with a slower reproductive rate are especially sensitive to disturbance , environmental changes and anthropogenic sources of stress because when populations of these organisms decline, recovery is especially slow . it takes a significant amount of time for these animals to reach reproductive maturity and they are commonly heavily invested in raising only one or two young ones every two to three years on average . therefore , populations of marine mammals with slow reproduction are in imminent danger when multiple sources of envirnmental pressure are acting in tandem over an extended period of time . The fewer fish the less that can reproduce.
More the reproductive rate, lesser the extinction and lesser the reproductive rate, more is the extinction.
What is reproductive rate?
The reproduction rate measures the conditions under which generations are replaced. This calculation can be made taking account of mortality (net reproduction rate) or without mortality (gross reproduction rate).
What is extinction?Extinction is a situation in which something no longer exists.
When the reproductive rate of marine mammals will be less, they will not be able to cover up the loss/death of their species caused by any reason and will ultimately lead to extinction.

Which type of vessels have a pulset A capillaries B lymph vessels C veins Darteries
Answer:
D:Arteries
Explanation:
Arteries carry oxygenated blood away from the heart to the tissues of the body. Veins carry blood depleted of oxygen from the same tissues back to the heart. The arteries are the vessels with the "pulse," a rhythmic pushing of the blood in the heart followed by a refilling of the heart chamber.
Malabsorption of some minerals, including _____ often occurs because the minerals form soaps with the unabsorbed fatty acids.
Malabsorption of some minerals, including calcium, magnesium, and zinc often occurs because the minerals form soaps with the unabsorbed fatty acids.
Deficiency of mineralsMinerals are parts of the nutrients made in the body or gotten from food sources that are essential for the maintenance of health and growth.
Examples of minerals are calcium, magnesium, and zinc which are capable of forming soap with fatty acids in a reaction called saponification.
Therefore when they are unabsorbed in the body, minerals form soaps with the unabsorbed fatty acids.

Describe the effect of adding trytophan to a culture of E. coli
Answer: High tryptophan: The tryptophan binds to the trp repressor and causes it to change shape, converting into its active (DNA-binding) form. The trp repressor with the bound tryptophan attaches to the operator, blocking RNA polymerase from binding to the promoter and preventing transcription of the operon.
Explanation:
Elisabeth is an oceanographer. On which of the following research expeditions would she travel from the photic zone to the aphotic zone?
A.) A snorkel trip from the intertidal zone to 55 feet off the beach
B.) A scuba trip from the surface down 100 feet
C.) A submersible traveling from the ocean surface to the abyss
D.) A research vessel from the beach to the open ocean
A research expedition traveling from the photic zone to the aphotic zone, is a submersible traveling from the surface of the ocean to the abyss.
What is aphotic zone and photic zone?Depending on the lighting, the waters are divided into:
PHOTIC ZONE → up to 200 m deep. DYSPHOTIC ZONE → between 200 m and 400 m deep. APHOTOTIC ZONE → below 400 m depth.With this information, we can conclude that a research expedition traveling from the photic zone to the aphotic zone, is a submersible traveling from the surface of the ocean to the abyss.

Water, compost , and chemical fertilizers is the best for maintaining the long-term health of farm soil.
What do you mean by chemical fertilizers?Chemical fertilizers, such as urea, diammonium phosphate (DAP), and single superphosphate (SSP), are used to maintain the shortage of nitrogen, phosphorus, and potassium in the soil.
Most fertilizers that are commonly used in agriculture contain the three basic plant nutrients: nitrogen, phosphorus, and potassium. Some fertilizers also contain certain "micronutrients," such as zinc and other metals, that are necessary for plant growth.
Chemical fertilizers will nourish your plant, but the minerals will not linger in your soil. By creating rich, nutrient-dense soil with organic materials, your lawn will have a better chance of thriving on its own tapping into stored minerals when needed.

if we have red veins and red blood how do we have blue veins in our bodies FIRST ONE TO ANSWER AND EXPLAIN GETS BRAINILEST PLEASE HELP
Answer:
The colors we see are the result of which wavelengths of light are reflected back to our eyes. Veins appear blue because blue light is reflected back to our eyes.
Blue light does not penetrate human tissue as deeply as red light does. As a result, veins that are close to the surface of the skin will be more likely to reflect blue light back to the eye.”
In short, our veins appear blue because of a trick that light plays on our eyes and how the light interacts with our body and skin. All color works this way as light is a combination of all colors and when it reflects off of certain materials, it absorbs some colors and bounces back others to our eyes.
