Humans and gorillas have one different amino acid in their hemoglobin
sequence. What does this say about the evolution of these two species?
A. Gorillas recently evolved from humans.
B. They have no common ancestors.
C. They probably have
recent common ancestor.
O D. They are probably the same species.
SUBMIT
Answer:
they probably have a recent common ancestor
Explanation:
They probably have recent common ancestor. Therefore, option (C) is correct.
What is evolution?Evolution is the process by which species change over time, usually through natural selection. The theory of evolution is supported by a vast body of evidence from many fields, including genetics, paleontology, and comparative anatomy.
Evolution occurs because of changes in the genetic code of organisms, which can be caused by mutations, gene flow, genetic drift, and natural selection. Over time, these changes can accumulate and result in the development of new species from ancestral forms. Evolution is a slow process that occurs over many generations, and it has been responsible for the incredible diversity of life on Earth, from the simplest bacteria to the most complex animals and plants.
The fact that humans and gorillas have one different amino acid in their hemoglobin sequence suggests that they have a recent common ancestor. This is because the hemoglobin protein plays an essential role in carrying oxygen in the blood and is highly conserved across species that share a common ancestor.

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

where can the DNA of bacteria be found
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.
How are nerve cells adapted to carry electrical messages?
Answer:
"The axon, the long, thin part of the neurone along which the impulse passes, is covered in a fatty myelin sheath, which acts as an electrical insulator."
Explanation:

Which of the following are ways that humans benefit from biodiversity?
Choose all that apply:
Reduced risk of flooding
Food harvested from ecosystems
Raw natural materials, such as wood or rubber
Pollination of crops
Recreation
Medicines derived from plants
Answer: to be honest I would click all
Explanation: Humans benefit from biodiversity as a source of food, medicine, and raw materials. Biodiversity ecosystems provide benefits to humans, like cleaning water or pollination of crops. ... Marine ecosystems store large amounts of carbon.
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.
