Researchers have found that mitochondria and chloroplasts in eukaryotic cells have their own DNA. This DNA is different from the DNA in a eukaryotic cell's nucleus. Chloroplasts and mitochondria use their own DNA and ribosomes to make some organelle-specific proteins.

What statement is best supported by this information?

A.
Modern cells could exist without mitochondria and chloroplasts.
B.
Early prokaryotic cells engulfed eukaryotic cells, which later became mitochondria and chloroplasts.
C.
Early eukaryotic cells engulfed prokaryotic cells, which later became mitochondria and chloroplasts.
D.
Mitochondria and chloroplasts could exist outside of modern cells.

Answer:

It is Alkene..........

Answer:

Alkenes

Explanation:

Alkene is a hydrocarbon chain that has a carbon to carbon double. Alkenes are considered 'acyclic' because it has one carbon to carbon double. Since they contain less than a maximum number of hydrogen atoms they are unsaturated.

The diagram shows four pairs of chromosomes from the karyotype of a normal human male.
Select the pair of sex chromosomes.

Answers

Answer:

According to the karyotype image, the sex chromosomes of a normal human male are those of the last picture, where both are different.

Explanation:

The sex chromosomes are those that determine the sex in a species, as in the human being and other species X and Y. XY chromosomes determine the male sex while the XX sex pair corresponds to the female sex.

In humans, the chromosomes are grouped by pairs with the same characteristics, that is, most pairs of chromosomes are identical. The only exception is represented by the male human sex chromosomes X and Y. This difference in the sex chromosomes causes the different sex chromosomes (picture) to be called heterogametic.

What energy carriers can enter the electron transport chain in mitochondria to generate ATP?

Answers

Answer: The electron transport chain consists of complexes which are the proton pump for the hydrogen ions across the mitochondrial membrane which allows the synthesis of the ATP (energy currency).

Explanation:

The electron transport chain occurs in the mitochondria. ATP synthase present in the inner mitochondrial membrane is a carrier of electron. FADH2 AND NADH two molecules supply high energy electrons from the citric acid cycle from the electron transport chain at complex I (NADH coenzyme Q reductase) and II (succinate dehydrogenase)respectively.

Turner syndrome occurs in females who instead of having two X chromosomes have either only one X chromosome or a fragmented X chromosome. Klinefelter syndrome occurs in males who have multiple X chromosomes. Consider the karyotype.

male with Turner syndrome
male with Klinefelter syndrome
female with Turner syndrome
female with Klinefelter syndrome

Answers

Answer:

male with Klinefelter syndrome

Explanation:

When people run quickly, they can sweat profusely. Their muscles undergo movement, and the loss of energy takes place. Based on this
description, in which two ways is energy conserved when people run?
-Heat energy is released from the body to the surroundings.
-Heat energy is taken from the surroundings to the body.
-Chemical energy is converted to mechanical energy that's used for muscle movements.
-Radiant energy is converted to mechanical energy that's used for muscle movements.
-Heat energy is converted to mechanical energy that's used for muscle movements.

Answers

Heat energy is released from the body to the surroundings and Chemical energy is converted to mechanical energy that's used for muscle movements are the  two ways in which energy is conserved when people run.

To do the things you do every day, you need energy. When you eat food, your body can use the chemical energy in the food to move your muscles, allowing you to breathe, walk, run, jump, lift things, and do everything else necessary for survival.

The chemical energy in food is converted into mechanical energy by moving muscles.

Chemical energy in the form of glucose in our food is converted into mechanical energy in the human body during movements such as running or lifting heavy objects. The muscles act as a transducer, converting chemical energy to mechanical energy through muscle contraction.

What are the locations and end products for the processes of transcription and
translation?

Answers

Answer: The transcription is the process of production of mRNA molecules from each separate strand of DNA individually and the translation is the production of protein by using the genetic information present in the mRNA.

Explanation:

The process of transcription occurs inside the nucleus of the cell in the eukaryotic cell typically not in prokaryotic cell whereas the translation process occurs in the cytoplasm with the help of ribosome.

mRNA is the product of transcription whereas the polypeptide chain of amino acids is the production of the translation in which further forms the protein.
