what do you think causes different phenotypes in organisms how does the phenotype depend on its genes (genotype)
Answer:
They difference in phenotypes is dependent on the genes. The more dominant gene will overpower a recessive gene, or if there are two recessive genes together, that will be the phenotype. When things are cross breaded they introduce different genotypes that allow for different looking phenotypes.
Example: Dominant blue flower (Bb) mixed with recessive yellow flower (bb)
B b
b Bb bb
b Bb bb
There is a 50/50 chance the offspring will be either blue or yellow
The differences in phenotypes are determined by genes. The more dominant gene will completely overwhelm a recessive gene, or if two recessive genes coexist, the phenotype will be that. When things are crossbred, unique genotypes are introduced, allowing for different-looking phenotypes.
What is phenotype?A "phenotype" is simply an observable trait. "Pheno" simply means "observe," and it derives from the same root as "phenomenon."
The differences in phenotypes are determined by genes. The more dominant gene will completely overwhelm a recessive gene, or if two recessive genes coexist, the phenotype will be that.
When things are crossbred, unique genotypes are introduced, allowing for different-looking phenotypes.
Thus, in this way, phenotype is dependent on genotype of the organism.

Yes or no and explain
Answer:
Yes, but the process is too slow
Explanation:
We pack almost everything in this material and plastic has become a very normal occurrence in the modern world. Each year, people used 1.6 million barrels of oil just to make plastic bottles.
On the other hand, nature takes about 1000 years to develop a single plastic object, while plastic material takes about 240 years.

restriction enzymes cut DNA at totally random places. true of false?
Answer:
False
Explanation:
Restriction enzymes, also called restriction endonucleases, are enzymes found in bacteria that cut DNA. They recognise target sequences and cut DNA at or near these sequences. These sequences are called restriction sites.
They act as a defense mechanism against invading pathogens. However, they are routinely used in molecular biology labs to perform DNA technologies such as genetic engineering.

two features of indirect democracy
Answer:
trump
Explanation:
There are two different types of cell transportation. Which of the following requires energy?
a. Facilitated Diffusion
b. Active Transport
c. Osmosis
d. Simple Diffusion
please help :))
Answer:
The type of cellular transport that requires energy is active transport (option b).
Explanation:
Active transport —unlike passive transport— involves the passage of molecules or substances through the membrane against a concentration gradient, a process that requires the use of energy.
In the case of active transport the energy for the process comes from the ATP molecule and the mechanism for this to be possible is by means of an ATPase incorporated into the transporter.
The transport of glucose and the sodium-potassium and calcium pumps are examples of this type of transport.
The other options are not correct because simple diffusion, facilitated diffusion and osmosis are passive transport mechanisms that do not require the use of energy.

Compare and contrast the TWO classes of "seeded "plants.
Answer:
The seed plants are often divided arbitrarily into two groups: the gymnosperms and the angiosperms. The basis for this distinction is that angiosperms produce flowers, while the gymnosperms do not.
Explanation:
The seed plants are often divided arbitrarily into two groups: the gymnosperms and the angiosperms. The basis for this distinction is that angiosperms produce flowers, while the gymnosperms do not. This is poor form, since it defines the gymnosperms by the absence of a character, and not by any features that the organisms actually share. The gymnosperms do share a number of features, but, as should be obvious from the above cladogram, they are not more closely related to each other than to the angiosperms (Anthophyta). The features shared by gymnosperms were likely present in the early ancestors of the flowering plants as well. It should also be noted that the "progymnosperms" are represented by a box of a different color, in order to make it clear that they are not actually seed plants, but rather are included here because they are believed to be the closest relatives of the seed plants.
Systematics within the seed plants is poorly understood. Part of the problem is that most of the major groups have gone extinct, and several of the groups alive today consist primarily of plants with highly derived morphologies. The above cladogram is based largely on the work of Jim Doyle, a professor at UC Davis, and Michael Donoghue, currently at Harvard, and is therefore somewhat preliminary. It includes some questionable groupings not explicitly supported in their papers.
6.L.14.4 Which is true of only animal cells?
A. Their cytoplasm contains organelles.
B. They do not have a rigid outermost layer.
C. The process of obtaining energy requires sugar.
D. They have organelles that are surrounded by membranes.
Only animal cells have the process of obtaining energy through sugar. Plants on the other hand undergo photosynthesis, which uses sunlight instead of sugar.
Hope this helps! Please correct me if I'm wrong :)
Answer:
B. They do not have a rigid outermost layer.
Explanation:
Several organisms, including bacteria and eukaryotes are heterotrophs- this means that they obtain energy through breaking down organic molecules like sugar, and amino acids made by producers.
Animal cells are eukaryotic; all eukayoted may be single-celled, or multicellular, and contain a nucleus containing genetic material along with membrane-bound organelles in their cytoplasms. Animal cells do not contain rigid cell walls, unlike other eukaryotic cell types like plant cells.
Where dose plastic come from?
Answer:
Plastics are derived from natural, organic materials such as cellulose, coal, natural gas, salt and, of course, crude oil. Crude oil is a complex mixture of thousands of compounds and needs to be processed before it can be used. The production of plastics begins with the distillation of crude oil in an oil refinery.

Answer:
C. The salt is dissolved by the water
Explanation:
When ionic compounds dissolve in water, the individual ions separate and get surrounded by water molecules—a process called solvation. Because the salt ions are charged, they dissolve much better in a polar solvent, which is also slightly more charged than a nonpolar solvent

Recall what you know about nervous tissue to answer the following questions. Nervous tissue can generate and conduct ____ signals that control the body.
answer choices are:
chemical
electrical
thermal
Answer:
Nervous tissue can generate and conduct electrical signals that control the body.
Explanation:
The neuron is the specialized cell that provides function to nerve tissue. Given the structure of the neuron, this cell is capable of creating and conducting information in the form of electrical impulses or signals, by depolarizing its cell membrane and generating action potentials.
The information generated and transmitted by the neurons allows the nervous system to obtain internal and external information of the organism, as well as to control all the body functions.
The other options are not true because nerve tissue does not generate or conduct thermal or chemical signals to perform its function.

1. cross-breeding; a method that unionizes gametes of differing genes to create a new individual
recombinant DNA
2. cultured DNA molecules from different biological sources
hybridization
3. a process of breeding organisms because of their specific traits
selective breeding
Answer:
Hybridization - a method that unionizes gametes of differing genes to create a new individual
Recombinant DNA - cultured DNA molecules from different biological sources
Selective breeding - a process of breeding organisms because of their specific traits
Explanation:
In biology, hybridization is the process of creating a hybrid by combining gametes of different species or varieties. An example of a hybrid is a liger - an offspring of a lion and a tiger.
Recombinant DNA is DNA created in the process of genetic recombination. Genetic material from multiple sources is combined, creating sequences that do not occur in the genome naturally.
Selective breeding is the process of breeding organisms with desirable characteristics. For example, a good dog breeder will breed only two completely healthy dogs in order to make sure that the puppies don't have any health issues often associated with the breed.

Molecules that make up living things and contain carbon are called __________ molecules.
Molecules that make up living things and contain carbon are called organic molecules.
Organic molecules are those that derive their three-dimensional configurations primarily from their carbon skeletons.
Organic molecules are essential for the birth, development and functioning of all cells that make up living organisms.
About organic molecules:
All organic molecules contain carbon and practically always hydrogen, it is also frequent that they have oxygen or nitrogen.These chemical elements enable multiple and covalent bonds to be established, allow carbon atoms to develop three-dimensional skeletons, and give rise to multiple functional groups. Proteins, vitamins, carbohydrates, lipids, and nucleic acids are organic biomolecules, which are synthesized by living organisms.Therefore, we can conclude that molecules that make up living things and contain carbon are called organic molecules, which a living being needs to develop normally.
