what is seedbed preparation?
Answer:
love means love you 19035
Answer:
Seedbed preparation is an important step that can optimize seed germination and survival rate. Final seedbeds can be prepared by disk, harrow, or chisel plowing. The means of preparation will vary with the species selected and the availability of equipment.
Explanation:
I really need you to answer this.
Answer
A
Explanation:
Some animals don't eat a specific pray, and other hunt more than one specie, which means that they are all food for other organisms that are stronger than them.

List two advantages for synthetic fertilizers
Answer:
Cheaper to purchase than organic
Nutrients are concentrated, only small amounts needed
Nutrients are quickly available for plant absorption
Answer:
They're faster acting than organic making them a good choice for aiding plants in severe distress from nutrient deficiencies. These fertilizers, which come as dry, granular pellets or water-soluble products, also provide even, consistent feeding.
Why do single-celled organisms divide?
A.to repair damaged cells
B.to transmit genetic material by reproduction
C.to reduce the number of chromosomes in the cell
D.to increase the number of chromosomes in the cell
Answer:
C
Explanation:
Single-celled organisms use cell division as their method of reproduction
The cellular mechanism that determines the independent assortment of maternal and paternal chromosomes is: Please choose the correct answer from the following choices, and then select the submit answer button. determined by their dominant or recessive inheritance pattern. separation of sister chromatids at anaphase II of meiosis. separation of sister chromatids at anaphase I of meiosis. separation of homologous pairs at anaphase II of meiosis. separation of homologous pairs at anaphase I of meiosis.
Answer:
separation of homologous pairs at anaphase I of meiosis.
Explanation:
Independent assortment law establishes that the alleles from two or more different genes distribute in gametes independently from each other. In other words, a gamete receives an allele from a gene that does not depend or influence the allele of another gene in the same gamete. This random distribution can only be applied to independent genes. These genes segregate independently after crossing over because they are located far away from each other.
When cell division is going on by meiosis, it involves the random and independent segregation of the alleles. During anaphase I (meiosis), the pairs of homologous chromosomes separate independently of each other. Each integrant of the homologous pair migrates to opposite poles of the cell. This separation generates different chromosomal combinations in the daughter cells. The process is as follows.
During metaphase I, homologous pairs together migrate to the equatorial plane, where they randomly aline with their kinetochores facing opposite poles. The random arrangement of tetrads is different in every cell going through the meiosis process. There is no equal alinement between two cells. When tetrads aline in the equatorial plane, there is no predetermined order for each of the homologous chromosomes of each tetrad to face one of the poles and then migrate to it while separating. Any chromosome of the homologous pair might face any of the poles and then migrate to it. Each of the chromosomes has two possibilities for orientation at the plane. During anaphase I, each of the homologous chromosomes migrate to the corresponding pole. When the new haploid cells are formed, the number of variations in each cell is also different and depends on the chromosomes that form that cell. This random order in the equatorial plane is what introduces variation into the gametes. It is almost impossible that two gametes resulting from meiosis will get the same genetic charge.
How many divisions take
place during meiosis in
order to produce the four
haploid (reproductive)
cells?
A. two
B. one
C. four
Answer:
two cell divisions happen throughout the overall process, so a result of four haploid cells are produced.
Explanation:
A because it consists of two nuclear divisons resulting in four nuclei that are usually turned into four new haploid daughter cells

If the shaded part is the trait then half would only be carriers and would not actually have the trait. It would need to be fully shaded. So only 4.
what are toes inside of the human body and what do they produce?
Answer:
Each toe consists of three separate bones and two joints, except for the big toe, which has only two bones — distal and proximal phalanges — and one joint, like the thumb in the hand. The phalanges are made up of the distal phalanges at the tip, middle phalanges, and proximal phalanges, closest to the metatarsals.

do you think applying any amount of force to any solid object would cause it to bend? why or why not
Answer:
An applied force affects the motion of an object. An applied force can be a push, pull, or dragging on an object. The action from a force can cause an object to move or speed up , to slow down , to stop, or to change direction

Which of the following claims correctly describes a kingdom of Domain Eukarya?
A. Kingdom Protista includes single-called organisms that lack nuclei
B. Kingdom plantae includes multicellular organisms that can move independently
C. Kingdom animalistic includes multicellular organisms that make their own food
D. Kingdom fungi includes organisms that get energy by decomposing materials in their environment
Answer:
D
Explanation:
1. protists have nuclei
2. plants don't move independently
3. animals don't make their own food
so option D is the best option
good luck
The following claims correctly describes a kingdom of Domain Eukarya is Kingdom fungi includes organisms that get energy by decomposing materials in their environment.
What are the main features of the Fungi kingdom?Fungi are heterotrophic and eukaryotic organisms that can be unicellular or multicellular. The vast majority of species are filamentous, and these filaments are called hyphae. Some fungi are formed by several densely packed hyphae, which form the so-called mycelium.
The Fungi Kingdom is represented by unicellular or multicellular eukaryotic organisms, being found in the most diverse types of environments. Fungi include mushrooms, molds, wood ears, lichens, among other organisms.

what happens when an atom has lost an electron comes in contact with an atom that has gained an electron?
Answer: When an atom that has lost an electron comes in contact with an atom that has gained an electron, usually the the two atoms would attract each other and form a compound. This compound would be ionic since it is governed by ionic bonding.
Explanation:
Different genotypes always produce different phenotypes. Explain, using an example, why this is NOT true.
Answer:
Different genotypes don't always produce different phenotypes because though AA & Aa are different genotypes, they are both dominant, therefore having the same phenotype.
Explanation:
Genotype:
AA Aa aa
↓ ↓ ↓
Phenotype:
dominant dominant recessive
(same phenotype) (different phenotype)

Over the past 300 years, how did the role of the ocean change with respect to the amount of carbon dioxide in the atmosphere
Answer:
Ocean plays the role of regulator.
Explanation:
The role of the ocean change with respect to the amount of carbon dioxide in the atmosphere because oceans plays a role of regulator and balancer. When there is high amount of carbon dioxide in the atmosphere due to burning of fossil fuels and volcanic eruptions so the ocean absorb that extra amount of carbon dioxide from the atmosphere while on the other hand, when there is decrease in the concentration of carbon dioxide in the atmosphere, the ocean gives its carbondioxide gas to the atmosphere to regulate the concentration.

How do mutations occur in the genetic code? This represents crossing over during meiosis.
a) During DNA replication, the original DNA strand GTC ACA GGC ATC is copied into complementary strand CAG CCG TAG. This is an example of deletion.
b)Mutations can only occur when passed on thorough reproduction. The majority of mutations are the result of exposure to mutagens.
c)A woman who has sickle cell anemia passes this disease on to her offspring. This means that the mutation for sickle cell anemia MUST occur in the woman’s gametes.
d)Mutations can be silent and not affect the organism that has them.
