How do oxbow lakes form? A. It is formed as lakes grow larger due to erosion and begins to look like an ox. B. It is formed when a bend in a river is cut off to form a lake. C. It is formed when a delta grows large enough to cut off a river to form a lake. D. It is formed when a dam stops the flow of a river and creates a lake.

Answers

Answer:

Oxbow lake is formed when a bend in a river is cut off to form a lake.

Explanation:

OPTON A - It is formed as lakes grow larger due to erosion and begins to look like an ox.

This statement is incorrect , as the shape of the oxbow lake is not like an ox , it is a horse-shoe shaped lake .

OPTION B - It is formed when a bend in a river is cut off to form a lake.

This statement is correct , as An oxbow lake is a U-shaped lake that forms to create a free-standing body of water when a large meander of a river is cut off.

OPTION C - It is formed when a delta grows large enough to cut off a river to form a lake.

This statement is also wrong, as a river delta is specified by this statement.

OPTION D - It is formed when a dam stops the flow of a river and creates a lake.

This statement is also false, since the creation of a reservoir is established by this statement.

FORMATION OF OXBOW LAKE -:The neck of the meander gets narrower and narrower progressively. The curve gradually grows so close that the river slices through the neck of the meander to take a new, straighter path. Sediment locks the end of the old loop over time. This leaves a region of water that is different, called an oxbow lake.

Hence , the correct option is B.

Bbbb

The mass of an atom is contained primarily in its _____. A. Electron Shell B. Nucleus C. Proton D. Size

Answers

The mass of the atom is contained mainly in the nucleus itself. The nucleus is composed of a number of protons and neutrons which are positively charged and neutrally charged sub particle components. The nucleus are surrounded by electrons.

The mass of an atom is contained primarily in its NUCLEUS.
An atom is made up of three sub particles, which are proton, neutrons and electrons. The proton and the neutrons are located in the nucleus of the atom while the electron are located outside the nucleus where they move about in continuous motion around the nucleus. The proton and the neutrons, which are located in the nucleus have the same relative mass of 1, which has been estimated to be about 2,000 times bigger than that of the electron, which has a relative mass of 0.0005. This shows that, the mass of an atom is located primarily in its nucleus.

What observation led researchers to propose that chloroplasts evolved from cyanobacteria? A) Both produce proteins. B) Both contain mitochondria. C) Both provide structure to cells. D) Both perform photosynthesis.

Answers

(D) Both perform photosynthesis is the observation that led researchers to propose that chloroplasts evolved from cyanobacteria.
Chloroplasts is the area where photosynthesis takes place. It is a green organelle in a plant cell. Pigments called the chloros in a chlorophyll are needed for the photosynthesis.
Cyanobacteria or blue-gree algae contains a blue photosynthetic pigment and a chlorophyll for photosynthesis.

Protists use all of the following methods to obtain energy except A. photosynthesis/ B. ingesting food/ C. converting atmospheric nitrogen/ D. absorbing food.

Answers

Protists consist of various types of organisms. They can either be autotrophs or heterotrophs. Autotrophs meaning, they can produce their own source of energy through the process of photosynthesis. Heterotrophs, when they obtain their energy through ingestion or absorption from other sources. So in the given question, the method of energy that protists do not do is option C. converting atmospheric nitrogen.

Algae, which are protists, can obtain energy through photosynthesis. Protists which primarily obtain food in heterotrophic methods such as ingesting and absorbing for nutrition. However, protists cannot obtain food through nitrogen fixation since all nitrogen fixers are prokaryotic and protists are eukaryotic organisms.

Answers

The process in which bacteria convert nitrogen gas into a usable form is **c. Fixation.** Nitrogen fixation is a vital step in the nitrogen cycle, where atmospheric nitrogen gas (N2) is converted into ammonia (NH3) or related compounds that plants can use for growth.
