Complete question:
Which survivorship curve best describes most marine organisms (few adults produce a large number of eggs and larvae).
Type IType IIType IIINone of the aboveAnswer:
Type III
Explanation:
There are three survivorship curves, each of them corresponding to different species according to their reproductive strategies.
Type I. Organisms do not tend to die when they are young or middle-aged, but they do when they are old. These species, in general, have a few descendants and parents provide much parental care to ensure their progeny to survival. Type II. Organisms that have more or less the same probabilities of dying in each age interval. These organisms can also have a few descendants and they can provide significant parental care. Type III. Only a few individuals survive their first period of life or their firsts years. However, the lucky ones to reach a certain age generally have a long life. These organisms have a lot of descendants at the same time, but they do not provide much parental care. This is the case of most marine organisms that produce a large number of eggs and larvae when they are adults, but they do not provide parental care.A particular triplet of bases in the template strand of a coding sequence of DNA is AAA.

Explanation:
A nerve impulse is an electrical charge running across a neuron. Explain why the simulation supports this explanation.
Answer:
Sudden reversal of the electrical charge across the membrane of resting neuron
Answer:
Stimulation of a neuron causes a change in the charge inside the cell from negative to positive. This change is caused by ions, which are atoms with an electrical charge, moving across the cell. This change within the cell is consistent with the definition of an electric charge.

If algae populations continue to decline, predict how this might impact the Great Barrier Reef food web.
Answer: the food web would crash.
Explanation: the great barrier reef's diversity would decline more and then the food web would crash since algae was the primary source, no ecosystem can live without a primary source to feed off of to gain energy and grow
Great barrier reef food web protects the coastline and is house to thousands of species. Algae is the primary producer on which the entire food web is based. If it continues to decline, ecosystem will crash.
The biggest coral reef in the world is the Great Barrier Reef. It is situated on Australia's northeastern coast. With a length of 1429 miles and more than 9,000 species, the Great Barrier Reef is enormous. One of the most biodiverse places on the globe, it. Over 3,000 different varieties of coral may be found on the Great Barrier Reef, yet despite supporting such a diverse range of life, the reef is threatened by climate change. Coral bleaching, which harms reefs and the creatures that dwell there, is being caused by changing temperatures and rising carbon dioxide levels.
A food web is a visual representation of how energy moves through an ecosystem. Food webs reveal which creatures in an environment devour one another. Trophic levels are divisions that can be made within food webs. Producers always come first in food webs.
Therefore, if algae (Primary producer) population continues to decline Great Barrier Reef food web will have a crash landing.

Looking at the image of the freshwater lake ecosystem in the reading, can you name biotic and abiotic factors in this specific ecosystem? What changes in this ecosystem would impact the biotic factors? A sample answer could include the following:
Biotic: Fish Crayfish Zooplankton Grasses
Abiotic: Sun Sedimentation Weather Changes:
Water pollution Air pollution Overfishing Dredging of the bottom of the lake
Answer:
Biotic factors include: Fish (phytoplankton-eater, zooplankton-eater, predator)
, Crayfish
, Zooplankton
, Grasses, phytoplankton, herbivorous insect, worms, etc.
Abiotic factors include: Sunlight, Rainfall, Sedimentation, Weather, Minerals, Temperature.
Changes that would impact the biotic factors include:
Water, air pollution
Human activities: such as overfishing, rechanneling of the water for purposes such as irrigation, domestic or industrial use, or dredging of the bottom of the lake.
Explanation:
An ecosystem is composed of biotic and abiotic factors. Abiotic factors are non-living environmental factors such as water, air, soil, sunlight, and minerals. In aquatic ecosystems, abiotic factors include substrate type, water depth, nutrient levels, temperature, salinity, and waterflow. Biotic factors are the living organisms in the ecosystem and they include animals, birds, plants, fungi, etc.
In the image of the freshwater lake ecosystem given,
Biotic factors include: Fish (phytoplankton-eater, zooplankton-eater, predator)
, Crayfish
, Zooplankton
, Grasses, phytoplankton, herbivorous insect, worms.
Abiotic factors include: Sunlight, Rainfall, Sedimentation, Weather, Minerals, Temperature.
Changes that would impact the biotic factors include:
Pollution: pollution such as water pollution and air pollution will adversely impact the biotic factors.
Human activities: such as overfishing, rechanneling of the water for purposes such as irrigation, domestic or industrial use, or dredging of the bottom of the lake.

On a scratch sheet of paper, complete the Punnett square of the cross between two heterozygous red-eyed flies (Rr). What color eyes will the offspring have?
Answer:
75% red, 25% other color (brown?)
Explanation:
A cross between two heterozygous red eye flies (Rr x Rr)
R r
R RR Rr
r Rr rr
The possible genotypes are RR, Rr, and rr. There are two possibilities of Rr.
Since the heterozygotes have red eyes, the red eye allele must be dominant. Therefore, RR and Rr genotypes will all have red eyes. That means 3/4 (75%) of offspring will have red eyes. 1/4 25% are h0m0zygous recessive (rr), and will therefore have the other eye color (question doesn't mention which colour this is, it is likely brown)
How do you know something is dead
Is this without equipment?
Depending on what organism you are talking about, animals that can be seen with the unaided eye you can tell that they are dead by studying their bodily movements such as the rise or falling of their chest.
Plants with the unaided eye, the best indicator is to take a branch or piece off and study the insides color, if it is green then mostly likely they are alive.
Now microscopic organisms are harder to say, it depends on what you are referring to.

How many chromosomes will be found in
each of the two new cells formed as a result
of mitotic cell division?
23 pairs of chromosomes will be found in each of the two new cells formed as a result of mitotic cell division.
WHAT IS MITOSIS:
Mitosis is a kind of cell division that results in the formation of two daughter cells with the same number of chromosomes as the parent cell. Mitosis is used for growth and tissue repair in living organisms. In mitosis, a parent cell divides into two new daughter cells, however, each cell possess the same number of chromosomes as the parent. In a somatic human cell, there are 23 pairs of chromosomes (46 chromosomes). If this cell undergoes mitotic division, then, there will be 23 pairs of chromosomes in each cell formed.Learn more: https://brainly.com/question/3327479?referrer=searchResults

Discussion Topic Worldwide, about twice as many people eat a plant-based diet as eat a meat-based diet. Aplant-based diet requires fewer resources to produce. It takes 28 calories of fossil-fuel energy to produce 1 calorie of protein from meat. In contrast, it takes only 3.3 calories of fossil-fuel energy to produce 1 calorie of protein from grain. With the population continuing to increase, some people believe it may be necessary to give up meat-based diets to ensure that there are enough resources to produce food for all Do you think that a plant-based or a meat-based diet is more nutritious, or are they both equally nutritious?
Why does a plant-based diet require fewer resources to produce? Do you think people should eat less meat? Why or why not?
Answer:
I think that they are both equally nutritious and that they give us the nutrition that we need. a plant- based diet uses less resources because they use less water to produce the food as it suppress all animal based products. I think people should eat less meat because sometimes people put unhealthy chemicals in food that can be harmful and not healthy as a source to people.
