Biology

katrin2010 [14]3 years ago
6 0
The Earth's atmosphere would have little or no oxygen. A by-product of photosynthesis is oxygen. Photosynthesis is the process by which green plants use energy from the sun to make their own food in the leaves. The process uses sun light, water and carbon dioxide to yield oxygen and simple sugars. The simple sugars are stored in form of starch for future use by the plants, while oxygen is either used for cellular respiration or released to the atmosphere. The process of photosynthesis adds oxygen to the atmosphere and uses carbon dioxide from the atmosphere.

Plants use carbohydrates to build things such as cellulose. How do plants acquire these building blocks to build mass?
koban [17]
I believe the correct response would be C. Plants acquire carbohydrates by producing them through the process of photosynthesis. This allows plants to then use the formed carbohydrates to build structural polymers, such as cellulose.

The surge in luteinizing hormone that occurs during the middle of the ovarian cycle triggers
avanturin [10]
<h2>Ovulation   </h2>

Explanation:

In women, luteinizing hormone carries out different roles in the two halves of the menstrual cycle

  • In week one to two of the cycle, luteinizing hormone is required to stimulate the ovarian follicles in the ovary to produce the female sex hormone, oestradiol
  • Around day 14 of the cycle, a surge in  luteinizing hormone levels causes the ovarian follicle to tear and release a mature oocyte (egg) from the ovary, a process called ovulation
  • For the remainder of the cycle (weeks three to four), the remnants of the ovarian follicle forms a corpus luteum
  • Luteinizing hormone stimulates the corpus luteum to produce progesterone, which is required to support the early stages of pregnancy, if fertilization occurs

Why is it important for geologists to use both relative and absolute ages to determine the age of rocks?
uysha [10]

Answer:

to help and determine the exact age of the rocks

Explanation:

The study of rocks strata is known as stratigraphy. It is useful and helps the scientist and the researcher to study the earth's crust and its past.

Scientist could age the rock using two methods. They are :

Relative ages

Absolute ages

Early scientist could determine the exact age of the rock of the earth's crust. They use to find the relative ages of the layers of the rocks and then determine how one rock layer is older or younger than the other. But with advancement and development of carbon dating, scientist could tell the exact age of the rocks found on the earth's crust.

The Scientists uses the relative as well as the absolute dating technique to date the rock layers. They organize the rock layers based on their age and scale from the oldest to the youngest on a geologic time scale. So an exact date of the rocks can be determine by using the two methods of relative age and the absolute age.

A non native species of fish is introduced into a lake. which would most likely prevent this fish from becoming an invasive spec
satela [25.4K]
The factor that will prevent the species from becoming an invasive one is predation.

If the species of fish introduced is an apex predator, there will be no organisms present to keep the population of the fish in check. Moreover, if the introduced species has a selective advantage over those that it shares the same niche with, then it is more likely to oust these species from the food chain by consuming all of their resources.
