What form is energy stored in at the end of photosynthesis?A. Water energy
B. Solar energy
C. Electron energy
D. Chemical energy

Answers

Answer 1

Answer:

Answer:

D. Chemical energy is the correct answer.

Explanation:

Chemical energy form is energy stored in at the end of photosynthesis.

At the end of photosynthesis energy from the sunlight is stored in the chemical energy.

Photosynthesis is a process through which organisms that contain chlorophyll pigment converts sunlight energy into chemical energy.

Plants produce food by photosynthesis utilizing light energy and chemical energy is that stores energy.

Answer 2

Answer: D. Chemical energy
The plant converts solar energy into food for the plants. doing this would be a chemical reaction. At the end of photosynthesis there would be chemical energy. :)

DNA profiling

Answers

A couple of the methods of molecular biotechnology are cloning and recombinant DNA.

Answer:

All

Explanation:

The study of molecular basis (study of protein and nucleic acid) of any biological activity through intervention of laboratory technology is termed as molecular biotechnology

There are several methods of molecular biotechnology such as -

a) DNA cloning

b) Bacterial transformation

c) Chromosome integration

d) DNA polymerase & synthesis

e) Molecular hybridization

f) Polymerase Chain Reaction (PCR)

g) Expression cloning

h) Gel electrophoresis

i) Macromolecule blotting and probing

j) Arrays

Etc.

Hence, all are methods of molecular biotechnology

Michelle wants to classify an organism that she is studying in lab. The organism is multicellular, makes its own food, and is unable to move around its environment. The organism that Michelle is studying can most likely be classified into Domain _______.

Answers

The domain in which this organism is included is Eukarya. As the name indicates, Eukarya domain includes all the organisms which are made up of eukaryotic cells. Eukaryotic cells are kind of cells which have well defined nucleus and membrane bound organelles.

Further, this domain named Eukarya comprises 4 kingdoms which are mentioned as under:

1) Plantae

2) Animalia

3) Fungi

4) Protista

These 4 kingdoms include several organisms of varying characteristics but an organism having the mentioned characteristics i.e. multicellular, makes its own food, and is unable to move around its environment is specifically included in Kingdom Plantae.

It's domain is eukarya. And it's kingdom is Archaeplastida or plantae.

Actin and myosin, found mostly in muscles cells, are made up of which type of macromolecule?Nucleotides
Proteins
Lipids

Answers

Answer: Proteins

Actin belongs to a family of globular multifunctional protein and myosin is a belongs a family of motor proteins. Both actin and myosin combines to form microfilaments. These are found in the eukaryotic cells. In humans and animals the combination of actin and myosin is responsible for contraction and relaxation of muscles in the presence of ATP.

Final answer:

Actin and myosin, which are primarily found in muscle cells, are macromolecules made up of proteins. These proteins are critical in muscle movement and function.

Explanation:

Actin and myosin are made up of proteins. Proteins are one of the macromolecules vital for building and repairing tissue. In the context of muscle cells, actin and myosin play a pivotal role. They interact to cause muscle contraction, a process vital for movement. Actin is a thin filament while myosin is a thicker one, and they slide past each other to cause the contraction of the muscle. Therefore, proteins have a substantial role in muscle movement and function.
