where can the DNA of bacteria be found​

Answers

Answer:

The DNA of most bacteria is contained in a single circular molecule, called the bacterial chromosome. The chromosome, along with several proteins and RNA molecules, forms an irregularly shaped structure called the nucleoid. This sits in the cytoplasm of the bacterial cell.

As the trait is dominant and controlled by a single gene, the mutation must have occurred on both
diploid copies. True or false?

Answers

The answer is false.

Human gets benefits from biodiversity such as food material, pollination of crops, medicines, etc. Hence, all options are correct.

What is biodiversity?

Biodiversity refers to the varieties of flora, fauna, fungi, bacteria, and all types of microorganisms in our ecosystem. There are billions of species of organisms present on the earth. The highest biodiversity is found in the ocean.

There are many benefits of biodiversity such as the risk of flood reduction because plants stop erosion, food produced by the producers, pollination of crops by pollinating agents, recreation, and raw natural materials like wood, vegetables, spices, and medicines derived from plants.

Human gets all these benefits from biodiversity. Therefore, all options are correct.

The image shows the path of a ball that’s thrown.
At positions (A,B,C, or D) and (D,E,F, or G), kinetic energy is maximum. At position (B,C,D,or E), potential energy is maximum.

Answers

At position (A) and (G), kinetic energy is maximum. At Position (D), potential energy is maximum.

At point A and G kinetic energy will be maximum while Potential energy is maximum at point D.

Kinetic energy (KE) is initially provided to the ball while it is still in contact with the throwing hand. Once the ball leaves the hand there is no input of energy. As the ball rises the KE is transformed to gravitational potential energy (GPE). This GPE is effectively stored in the height of the ball.Now, when the ball falls back to the ground its potential energy is transformed into kinetic energy, which will continue increasing as it gains momentum, until it finally collides with a surface.

Which of the following means a hormone that aids in growth of gonads?
Glycogenesis
Thyrotoxic
Pancreatitis
Gonadotropin

Answers

Answer:

thyrootoxic

Explanation:

The hormone which aids in the growth of gonads  is Gonadotropin. The correct option is gonadotropin.

Gonadotropins are  defined as the hormones which  play an important  role in the growth and development of gonads. The gonads refer to the male and female reproductive organs, such as the testes and ovaries. Gonadotropins stimulate the production of sex hormones and even  regulate the reproductive processes. These homones are essential for the normal functioning of the reproductive system.

Gonadotropins are  classified as glycoprotein hormones  which are secreted by gonadotropic cells of the anterior pituitary which is present in vertebrates.This family includes the mammalian hormones follicle-stimulating hormone (FSH) and luteinizing hormone (LH), the chorionic gonadotropins, human chorionic gonadotropin (hCG) and equine chorionic gonadotropin (eCG),as well as at least two forms of fish gonadotropins.

Thus, the correct option is gonadotropin.

Which type of tissue carries messages?
A. Nervous tissue
B. Connective tissue
C. Muscle tissue
D. Epithelial tissue
SUBN

Answers

Answer:

Nervous tissue

Nervous tissue is responsible for carrying messages throughout the body. It is made up of specialized cells called neurons, which are able to transmit electrical signals. These signals allow the body to respond to stimuli and coordinate its movements. Hence option A is correct.

Connective tissue provides support and structure to the body. It is made up of cells that are embedded in a matrix of fibers. The fibers can be made of collagen, elastin, or other proteins. Connective tissue can be found in many different parts of the body, including the bones, muscles, and skin.

Muscle tissue is responsible for movement. It is made up of cells that can contract and relax. There are three types of muscle tissue: skeletal muscle, smooth muscle, and cardiac muscle.

Skeletal muscle is attached to bones and is responsible for voluntary movement. Smooth muscle is found in the walls of internal organs and is responsible for involuntary movement. Cardiac muscle is found in the heart and is responsible for pumping blood.

Epithelial tissue covers the body and lines internal organs. It is made up of cells that are tightly packed together. Epithelial tissue protects the body from infection and helps to regulate body temperature.
