Answer:
The atom, the basic building block of matter, consists of a core nucleus surrounded by negatively charged electrons. Inside the atom nucleus contains a mixture of positively charged protons, and electrically neutral neutrons. All atomic electrons bind to the nucleus through electromagnetic force. A ground of electrons bound together will form individual molecules. An atom with an equal number of protons and electrons will hold neutral. An ion has positive or negative charge, either through a lack of electrons or an electron excess. The number of protons determines the formation of chemical elements, while as the number of neutrons determines the element's isotope. Most of the atom's mass has a concentration compacted within its nucleus; however, protons and neutrons hold about the same mass. Electrons bound to atoms hold a percentage of stable energy levels, otherwise known as orbitals, which undergo transitory processes through absorbing or omitting photons with equal energy levels. Electrons determine an element's chemical properties, thus influencing an atom's magnetic properties.

gene is a segment of DNA on a chromosome. How are genes related to the proteins made by a cell?
Answer:
The DNA in genes is transcribed into RNA and translated into proteins
Explanation:
The sequence of DNA in a gene is transcribed into a messenger RNA (mRNA). This sequence of this mRNA is translated into a sequence of amino acids that form a protein.
The sequence of DNA in a gene directly affects the amino acids, and therefore the structure and function of, a protein.
Answer:
The structure of the genes in a cell determines the structure of the proteins made by the cell.

What describes G and why they face the watery inside and outside of the cell
Answer:
Because they are hydrophilic
Explanation:
The cell membrane is made up of a phospholipid bilayer. The phospholipid bilayer is made up of an arrangement of phosphate heads, which are (attracted to water) hydrophilic, and fatty acid tails, which are hydrophobic. (repelled by water).
Because they are attracted to water, the phosphate heads face the outside of the cell, where the water is

Explanation:
what makes angiosperm more advance than gymnosperm
Answer& Explanation:
Angiosperm is more advanced due to the mechanism of protection it has since developed as opposed to its predecessor, gymnosperm. Angiosperms could be deemed the inventors of animal-mediated pollination or dispersal, whereas gymnosperms mostly depend on wind-mediated pollination (which is far more of a gamble than animal mediated).
1) Angiosperms seeds are enclosed in fruits, which increases the chances of dispersal by either wind, water, or animals. Animals can eat the fruit and disperse the seeds via feces or by brushing the fruit off of their fur coats new areas of the terrain.
2)The development of flowers. Flowers are especially important because depending on the flower it can attract a set species of animals in order for pollination to occur. That species of animal could only focus on those few flowers and would allow the female part of the flower to receive pollen (produced by the male part of the flower) from all over the place. This theory is also applicable to animal mediated fruit dispersal.

Cytokinesis – division of the cytoplasm resulting in two identical d_______________ cells.
Answer: daughter
Explanation: Cytokinesis results in the division of cytoplasm in a parental cell, creating 2 identical daughter cells.
Hope this helps!
Cytokinesis, the division of the cytoplasm resulting in two identical daughter cells, is caused by the mitosis process, as here the two daughter cells get an equal amount of the genetic contents.
What is the significance of cytokinesis in mitosis?It is very important in mitosis because it aids in the division of two cells from one cell during the cell division process and results in the formation of two genetically identical daughter cells; without cytokinesis, the chromosomes would remain in the same cell, resulting in mutation as multinucleated cells are formed in such a process.
Hence, cytokinesis, the division of the cytoplasm resulting in two identical daughter cells, is caused by the mitosis process, as here the two daughter cells get an equal amount of the genetic contents.

Using information from the diagram, state one reason why the movement in the third image represents active transport
Answer:
A protein or ion has passed through the "pump" or carrier proteins and move within the cell.
Nvm short and sweet ;)
Further info..
To move substances against a concentration or an electrochemical gradient, the cell must use energy. This energy is harvested from ATP that is generated through cellular metabolism. Active transport mechanisms, collectively called pumps or carrier proteins, work against electrochemical gradients. With the exception of ions, small substances constantly pass through plasma membranes. Active transport maintains concentrations of ions and other substances needed by living cells in the face of these passive changes. Much of a cell’s supply of metabolic energy may be spent maintaining these processes. Because active transport mechanisms depend on cellular metabolism for energy, they are sensitive to many metabolic poisons that interfere with the supply of ATP.
How do limiting factors determine the carrying capacity of an ecosystem ?
Answer:
Limiting factors determine carrying capacity. The availability of abiotic factors (such as water, oxygen, and space) and biotic factors (such as food) dictates how many organisms can live in an ecosystem. Carrying capacity is also impacted by the availability of decomposers.
Explanation:
Carrying capacity is determined by limiting variables. Limiting factors can be divided into two categories: those that depend on the density and those that don't.
What are the limiting factors?Limiting factors can be divided into two categories: those that depend on the density and those that don't. These names are accurate in their meanings.
No matter how big or little, expanding or contracting, the population is affected by density-independent causes. For instance, regardless of the density of any one population, a wildfire that burns through a dense forest in the Everglades has a significant effect on every population in the area.
The majority of density-independent limiting variables fall into the abiotic (nonliving) group, which includes wildfire. Hurricanes, pollution, and seasonal climate extremes are other density-independent variables.
Therefore, Carrying capacity is determined by limiting variables. Limiting factors can be divided into two categories: those that depend on the density and those that don't.

Geese fly in a v-like formation when migrating. Which statement is evidence that supports advantages of this group behavior? (4 points)
A) Birds can work together to find food and shelter.
B) Birds conserve energy and reduce wind resistance.
C) Birds need to move faster to avoid being seen by predators.
D) Birds can compete for mates when they fly together.
Answer:
B
Have a nice day :D
Birds conserve energy and reduce wind resistance when they fly in V-like formation.
Why Geese fly in a V-like formation?Flying in a v-like formation allows geese to conserve energy and reduce wind resistance as they migrate. The lead goose breaks the wind for the rest of the group, which allows the other geese to fly more efficiently and use less energy. This group behavior helps the geese to cover long distances during migration, as they are able to fly for longer periods of time without tiring.
The other options do not provide evidence of advantages of this group behavior. Option A) may be true, but it is not specific to flying in a v-like formation. Option C) is not necessarily related to group behavior, as geese may need to move faster for other reasons. Option D) is not relevant to the topic of migration.

In one plant species petal color follows INCOMPLETE DOMINANCE. If there
are alleles for both red and white plants, what would a heterozygous plant's
phenotype be?
Red
Pink
White
Red and White
Answer:
Pink
Explanation:
Incomplete dominance is when one allele is not entirely dominant over the other. The resulting phenotype of the heterozygote is intermediate between the two alleles. That means the flowers would be pink.
Red - no, this would be true if red was dominant to white
Pink - yes, this is an intermediate phenotype
White - no, this would be true if white was dominant over red.
Red and White - no, this would be true if the alleles were co-dominant and both equally but independently expressed.
