Explanation: angina is a type of chest pain that occurs due to decreased blood flow into the heart this can harm animals and people. there is also - - - arrhythmia,which is or an irregular heartbeat or heart rhythm,

- congenital heart disease, in which a problem with heart function or structure is present from birth.

-coronary artery disease, which affects the arteries that feed the heart muscle.

- Heart attack, or a sudden blockage to the heart’s blood flow and oxygen supply this can kill. heart failure, wherein the heart cannot contract or relax normally,

- dilated cardiomyopathy, a type of heart failure, in which the heart gets larger and cannot pump blood efficiently and the last one is

- hypertrophic cardiomyopathy, in which the heart muscle walls thicken and problems with the relaxation of the muscle, blood flow, and electrical instability develop

these are only a few that can harm or even kill a living thing like and animal or person these things are really harmful.

Which three statements are true about the energy flow in an ecosystem

Lady_Fox [76]

Ecosystem energy flow. Energy's life moves. The energy cycle is based on the flow of energy in an ecosystem through various trophic levels. The cycling energy and nutrients obtained from various external sources maintain our ecosystem.

The responses are A, B, and E. A) Because the sun provides the entire ecosystem with energy, it is a major source of energy. B) because photosynthesis is the process in which plants convert radiant energy from the sun into chemical energy to form sugar-known glucose. E) I believe because, as it moves throughout the ecosystem, the amount of energy at each trophic level decreases.

I hope this helped!!!

Which statements describe thigmotropism check all that apply

Finger [1]

Description of thigmotropism is given below.

Explanation:

1. Thigmotropism is a plant’s response to touch.It is a plant’s response to an external stimulus.It can occur quickly or slowly.Thigmotropism may involve the closing and opening of plant leaves.

2. Thigmonasty or thigmotropism can be define as the response of touch shown by the plants. Here, touch is the external stimulus. It can be define as the movement of the plant parts in response to the external stimulus that is contact or touch. It is also known as Haptotropism. The plant may change it's orientation, shape and size of the plant parts.

3,The thigmotropism can be positive or negative depending upon the visual response shown by the plants. The response shown by the plants is generally fast but may be slow. This response is shown by the plants in cases of danger of herbivory.Some plants like Mimosa pudica or touch me not plant shows thigmotropism by closing their leaves on touch

What is unusual about the genetically-inherited mitochondrial disease LHON as compared to the genetically-inherited disease sick

Schach [20]

Answer:

Explanation:

LHON (Leber Hereditary Optic Neuropathy): Is a disease that is characterized by loss of vision in young adults.

Sickle cell anemia: Is a disease characterized by production of abnormally shaped red blood cells, that is, not round in shape as normal but are 'sickle' shaped or elongated/crescent shaped.

Both diseases are heritable But LHON is caused by mutations existing in the mitochondrion thus only inherited maternally.

Sickle cell anemia is caused by mutations in the HBB gene which produces the beta subunit of hemoglobin. It is inherited from recessive genes of both parents.
