Explanation:

When a flower takes sunlight and turns it into food for the plant

Answer:

Photosynthesis is the process is which plants and other organisms transform light energy into chemical energy.

Explanation:

Example :

How plants convert energy from water, air, and sunlight into energy to grow. The water from the plants leaves evaporates through the stomata, and taking its place, is carbon dioxide. Which is what plants need to make food.

An offshore oil platform houses a drill for drilling oil. The drill descends from the platform and enters the ocean. At the bottom of the ocean, the
drill starts to dig into the rock. It continues drilling into the rock for another 7,000 feet and then stops. Where does the drill stop?

in the biosphere
in the geosphere
in the atmosphere
in the hydrosphere

Answers

Answer:

in the geosphere

Explanation:

The drill will eventually stop within the geosphere.

The biosphere is the region of the earth populated by living organisms. The geosphere is the region of the earth made up of solid rock The atmosphere is the gaseous part of the earth. The hydrosphere is the liquid part of the earth or where water dominates the earth.

The drill pierces through the geosphere as it initially passes through the hydrosphere. Eventually, the drill stops within the geosphere.

Answers

Answer:

Doppler Red-Shift Evidence

Explanation:

The Doppler red-shift of light observed from distant stars and galaxies gives evidence that the universe is expanding (moving away from a central point). This allows for Big Bang Theory, because after a “bang” occurs all of the matter moves away from the point of origin.

1.How can we trace the lines of descent between species?


Answers

Looking at the features of past species you can determine how old and what differences they have from fossils.

We can trace the lines of descent between species by three methods that are comparative anatomy, comparative embryology, and molecular genetics.

What is phylogenetics?

Phylogenetics is the study of evolutionary relationships among biological entities – often species, individuals or genes (which may be referred to as taxa).

Pleiotropy is a tough word, not going to lie. It really just means that one gene can control several different traits. Marfan syndrome is an example of a genetic disorder where the presence of one gene causes many different traits to appear. Some evidence suggests that President Abraham Lincoln could have had Marfan's, but the absolute best example (in my opinion) is Peter Mayhew (the original actor that played Chewbacca!) who was over 7 feet tall! What are some (list at least 3) of the phenotypic traits for an individual who has the Marfan genotype?

Answers

Answer:

An example of a condition that exhibits genetic heterogeneity is ... Polygenic means. the traits are determined by more than one gene.

Explanation:

The element which is responsible for this is the Cilia. The form found in a human's respiratory system are known as Motile Cilia and basically act as brooms on the respiratory epithelium lining the respiratory tract. Huge waves of Motile Cilia communicate with one another in order to be able to effectively clean up all dirt and mucus from the lungs in a very organized and unified manner. This helps maintain our respiratory system running as effectively as possible.

[tex]\huge\textbf{Cellular Respiration:}[/tex]

Cellular respiration is the process through which cells convert sugars into energy. The energy comes from the fuel molecules such as Glucose(sugar) or Lipids(fats). In cellular respiration, Glucose molecule is dismantled in the presence of oxygen. The bonds between the glucose break forming a simpler molecule and energy is released in small amounts. Some of the energy is stored by cell in the form of ATP while rest is lost as heat. So, ATP is formed from glucose through endergonic and exergonic reactions. The aerobic breakdown of glucose molecule accompanying synthesis of ATP is called celluar respiration. Carbon dioxide and water are produced as Waste Products.
