Chromosomes determine all inherited traits because they are made up of DNA.
What are the functions of chromosomes?Chromosomes allow DNA to be accurately copied during these cell divisions. So one more time. Chromosomes are found in the nuclei of our cells and allow DNA to be accurately copied during cell division. This ensures that our inner workings proceed smoothly and efficiently.
The main function of chromosomes is to carry the DNA and transfer the genetic information from parents to offspring. Chromosomes play an important role during cell division. They protect the DNA from getting tangled and damaged.
Chromosome are the thread-like structures intermingled with each other in the nucleus. They carry genes that help in the transfer of characters from the parents to the offspring and thus play an important role in the inheritance of characters.

Which statement describes how this ecosystem is likely to change after many years of ecological succession? A The variety of fish species will increase. B The number of plants will increase. C The level of the water will increase. D The elevation of the hills will increase
Answer: C) The level of water will increase.
Explanation:
Since the water is in the center of the trees, it will rise because of the shape of the ground. Water is a destructive force, so it will break down the soil and ground. This means the trees and plants will also go away, and the pond will expand to an even bigger body of water. The answer is C) The level of water will increase.

Is it yes or no? I’ll brainliest u if u get it right!
Answer:
No
Explanation:
I think No. because matter can neither be created nor destroyed...chemical change cannot alter the number of atoms in a given reaction. The atoms can only rearrange so that it can yield a new molecule/compound but the number of atoms should stay the same.

How is a population impacted when biological diversity is increased?
Does an increase in biodiversity always affect an ecosystem positively? Why or why not?
Are there any environmental factors that could impact species diversity in your neighborhood? Explain.
Answer:
Question one: Greater biodiversity in ecosystems, species, and individuals leads to greater stability. For example, species with high genetic diversity and many populations that are adapted to a wide variety of conditions are more likely to be able to weather disturbances, disease, and climate change. Question two: If those resources limit growth, then increasing functional richness should lead to greater total productivity and decreased loss of resources from the ecosystem. Facilitative interactions among species could also lead to increases in ecosystem pools or process rates as species or functional richness increases. Question three: Important direct drivers affecting biodiversity are habitat change, climate change, invasive species, overexploitation, and pollution.

a layer of sandstone is found on top of a layer of shale. what most likely happened in this area?
a. sea level stayed the same
b. sea level dropped
c. sea level rose
The most possible outcome of the given scenario is dropping of sea level. The correct option is b.
What is sandstone?The layers of rocks are related because they contain fossils. Others are formed by mountain erosion and weathering, and the particles are transported and deposited in the sedimentary basin, where they are cemented over hundreds of years to form layers.
Sandstones are siliciclastic sedimentary rocks with sand-sized grain. The framework's main mineral constituents are quartz, feldspar, and rock fragments.
Sandstone is made up of ancient stream, deltaic, and beach deposits. Sandstone is used in a variety of applications, including steel furnace liners, building stone, and so on.
Because a sandstone layer is found on top of a shale layer, the most likely outcome of the given scenario is a drop in sea level.
Thus, the correct option is b.

Which statement best explains how the mass of an atom is organized?
Most of the mass is contained in the nucleus.
The mass is spread evenly throughout the whole atom.
The mass is spread evenly throughout the electron cloud.
Most of the mass is contained in the electron cloud.
Answer: A
Explanation: most of the mass contained in the nucleus.
Most of the mass of an atom is contained in the nucleus. So the correct option is A.
What is atomic mass?The amount of matter that is contained in an atom is defined as the atomic mass of an atom. In mathematical terms, atomic mass is 1/12th of the mass of a carbon-12 atom. This is assigned an atomic mass of 12 units.
The unit for measuring atomic mass is called Dalton after the English scientist John Dalton.
Atomic mass is expressed as the sum of the mass of protons and neutrons. Protons are positively charged particles and neutrons are particles with no charge.
Atomic mass is expressed as the mass of protons and neutrons because protons and neutrons are present in the nucleus. Thus, it is said that most of the mass of the atom is concentrated in the nucleus.
The mass of electrons is comparatively less than the mass of protons and neutrons combined. Also, electrons are present in the atomic shells of the atom.
Therefore the correct option is A.

1. Water flows from a stream to a lake.
2. Gravity moves rocks to another location.
3. Lions use energy to catch other animals for food.
4. Bears dig big holes in the ground to protect their young.
Answer: D
Explanation:
Bears are living so they are biosphere while the rocks they and Are interacting with are geosphere so it’s biosphere interacting with geosphere hence, D because two spheres interact and gravity isn’t a sphere water is interacting with hydrosphere which arent different so tis basically hydrosphere with hydro and lions use energy is just biosphere with biosphere and last one makes sense cuz it’s two different bio and geo!
