Explanation:
Well, one could use a magnet to see if it's ferrous. One could melt it to check which type it is, use a metal detector, or just use their senses: If it dings or clinks like metal, and feels like it’s texture. If it polishes with metal polish, is reflective, can be shaped or shape when heated… It usually is a metal. If it rusts, or oxidizes, it is or contains metal. If it “smells" like metal, most likely, it is metal. Finally, if it walks like metal, and quacks like metal, most likely we have a metal

What concept suggests that small bacteria were engulfed by larger cells to become mitochondria and help to self flourish and become a eukaryotic cell
Answer:
Endosymbiotic theory
Explanation:
The concept that hypothesized that small bacteria were engulfed by larger cells to become the mitochondrion and eventually become a eukaryotic cell is known as symbiogenesis or the endosymbiotic theory.
The endosymbiotic theory argues that organelles like mitochondrion and the chloroplast found in modern-day eukaryotic cells were formerly prokaryotic microbes. These microbes got ingested by primitive, amoeba-like eukaryotic cells that were first formed but instead of dying, the engulfed microbes found a way to symbiotically coexist with their hosts, eventually forming the organelles - aerobic microbes forming the mitochondrion and photosynthetic microbes formed the chloroplast.

Answer:
A B and C but not D
Explanation:
Moving from a Hight concentration gradient to a low concentration gradient means moving from an area where a substance in quantity to an area where it is lower in quantity. D is the only one showing something to be moved against a concentration gradient because there are more squares inside the cell than outside the cell yet the squares are still being moved into the cell.

Which organelles must work together to provide food and energy to a plant cell?
Answer:
Mitochondria are the working organelles that keep the cell full of energy. In a plant cell, chloroplast makes sugar during the process of photosynthesis converting light energy into chemical energy stored in glucose.
Chloroplast and mitochondria are organelles that must work together to provide food and energy to a plant cell.
Plants are living organisms that are capable of nourishing themselves from inorganic substances.
The complex chemical process by which they manage to do so is called photosynthesis and it takes place in chloroplasts.
Chloroplasts are elliptical-shaped organelles - their number varies between 20 and 100 in each plant cell - found in leaves and possessing the enzymatic machinery necessary to transform solar energy into chemical energy and, finally, into food.
The plant cell needs energy to grow and multiply and the mitochondria provide most of this energy by performing the last stages of the breakdown of food molecules.
Its main function is to supply the electron carriers (ATP), a product of cellular respiration, which provide the energy that the cell needs.
Therefore, we can conclude that within the leaves of plants, in the chloroplasts of plant cells, the chemical process that transforms inorganic matter into food takes place and the mitochondria are the energy-producing organelles.

what would the chromosome to the right be called?
Answer:
The two identical chromosomes that result from DNA replication are referred to as sister chromatids. Sister chromatids are held together by proteins at a region of the chromosome called the centromere. Chromosomes undergo additional compaction at the beginning of mitosis.
Explanation:
Based on the position of centromere and length of chromosomal arms, the chromosomes are classified into 4 groups:
(1). Telocentric chromosomes.
(2). Acrocentric chromosomes.
(3). Sub-metacentric chromosomes.
(4). Metacentric chromosomes.

This map shows the counties in Montana that are prone to dam failure. If you were in charge of flood control in Montana, where would your biggest areas of concern be? What other data would you collect about these areas or about local weather patterns to help you make a flood-control plan for the state?
Answer:
The focus would be the western side of the state and several counties in the central part of the state because there are many high-risk dams in these areas. Knowing what communities and structures are located around these dams, the average precipitation rate, and projected rainfall totals would be helpful in designing a flood-control plan. Knowing the age and condition of each dam would be important for setting priorities in the plan.

Acid deposition may be also known as Acid rain. It includes the form of precipitation with several acidic components like nitric acid and sulfuric acid.
These precipitations finally falls on the earth from the atmosphere in the form of rain, snow, fog, etc., and are deposited on tall trees, buildings, and objects, and lose their natural beauty.
Therefore, the most likely cause of the effect shown in the given photograph is Acid deposition.
