Answer:
A cell cannot just keep growing because the part of the inner portion of the cell grow quickly as compared to outer side of the cell i. e. cell membrane. So we can say that cell membrane is the limited factor which doesn't allow cell to grow bigger in size. The growth of organisms increases not because of cell size increases, it is due to the number of cell increase because of cell division.

The Alligator and the Python are competing for top predator. What affect can the introduction of a non-native species have on an ecosystem?
Answer:
If a non native species got introduced then it would hurt the animals already there because there is no animals that are hunting it down. Also it would cause a imbalance in the food chain which can cause so animals to become extinct. If the animal is left unchecked then that animal can become the best in the food chain because nobody can get rid of it.
Explanation:
Explain why each chromosome must become two strands before the cell divides.
Answer:
To allow transcription enzymes to access the DNA strand
Explanation:
The DNA double helix is made up of two complementary strands wound around each other, and tightly packaged as chromosomes.
DNA and RNA polymerases promote either DNA or RNA synthesis by attaching free nucleases to parent strands (a), which are then unwound and isolated by helicases (b). DNApolys synthesize DNA in a 5'-3 ' direction; owing to its restricted flow, there are only two types of replication: continuous from the point of differentiation of chromosomes, fork, and discontinuous from the fork.

During your summer internship at a laboratory, you are given the opportunity to view a chimpanzee zygote under a microscope. You see that it has 48 chromosomes. How many chromosomes would you expect to find in a chimpanzee’s egg cell?
Answer:
If the chimpanzee’s zygote has 48 chromosomes, one would expect to find 24 chromosomes in a chimpanzee’s egg.
Explanation:
In a living organism, somatic cells are diploid and possess the full chromosome load, while gametes -sex cells- possess half of the total chromosomes, they are haploid.
The zygote of any organism that reproduces sexually results from the union of a male gamete and a female gamete, so its chromosome load is complete.
This means that if the chimpanzee has 48 chromosomes in its cells, the female sex cell - the egg - has 24 chromosomes.

4. One example of a carbohydrate that stores
energy is sc.6.L.14.2
A.fat
B.Hair
C.keratin
D.sugar
Answer:
The answer to your question is D, Sugar
Final answer:
The correct option for a carbohydrate that stores energy is D. sugar, which includes glycogen, a polysaccharide used by animals for short-term energy storage.
Explanation:
Carbohydrates are fundamental biological molecules that serve various roles, including energy storage. An essential simple sugar, glucose, shows the compact and immediate energy supply carbohydrates can provide. However, for longer-term storage, animals use a polysaccharide known as glycogen. Glycogen is made from hundreds or thousands of glucose units and is particularly abundant in liver and muscle cells. It serves as an energy reserve and is utilized when the body is fasting to maintain metabolic balance. Unlike fats or proteins, glycogen can supply the energy quickly due to its more accessible structure for enzymatic breakdown. This is why glycogen is a primary form of energy storage in animals.
The correct option from the list provided that is an example of a carbohydrate that stores energy is D. sugar. The sugars, specifically in the form of glycogen, are utilized by our bodies for short-term energy storage. This is in contrast to fats, which serve as long-term energy reserves but are not carbohydrates.
Hybridization _____.
occurs frequently in nature
is the process of gene combination in a lab
usually produces offspring that cannot reproduce
creates genetically identical offspring
Answer:
The correct answer is: c) usually produces offspring that cannot reproduce.
Explanation:
Hybridization, also knowns as selective breeding, is an artificial process that involves selecting parents with specific characteristics in order to obtain an offspring with the same traits.
Hybridization is very common and has been performed by humans for thousands of years: from selective breeding crop plants, to do so with dogs in order to create more desirable breeds.
Option A is incorrect because hybridation does not occur in nature, it is an artificial process.
Option B is incorrect because hybridation often happens when the selected parents are chosen to reproduce (by a human).
Option D is correct because an important amount of hybrids are sterile (for example: mules).
Option D is incorrect as well because the offspring is not identical: it shares a combination of genes from both parents.
Answer:
usually produces offspring that cannot reproduce
Explanation:
Hybridization is the process of crossing two organisms usually of different species, genus or families but of desirable characters to produce organisms known as hybrids.
Hybrid organisms combine the characteristics of both parents and because of the difference in genetic composition of the parents, they are often sterile and hence, cannot reproduce.
Therefore, hybridization usually produces offspring that cannot reproduce.

Write two examples of conclusions Mendel reached about inherited traits after completing his experiments with pea plants.
WILL GIVE BRAINIEST
Final answer:
Mendel reached two conclusions about inherited traits: the Law of Segregation and the Law of Independent Assortment.
Explanation:
Mendel reached two conclusions about inherited traits after completing his experiments with pea plants:
Law of Segregation: Mendel observed that the two alleles for each trait separate during the formation of sex cells. This means that each parent contributes one allele for a specific trait to their offspring. For example, when a plant with yellow smooth peas is crossed with a plant with green wrinkled peas, the resulting offspring will inherit one allele for pea color (either yellow or green) and one allele for pea texture (either smooth or wrinkled).
Law of Independent Assortment: Mendel found that the inheritance of one trait is not influenced by the inheritance of another trait. For instance, the alleles that code for different traits, such as pea color and pea shape, sort independently during meiosis. This means that the expression of one trait does not affect the expression of another trait in the offspring.
Science question about nucleotide base pairs and dna, fill in the spaces
Answer: a) deoxyribose sugar
b) guanine
c) adenine
d) phosphate group
Explanation: A DNA is a double stranded nucleic acid molecule. The building blocks of DNA are the nucleotides. A nucleotide is consists of deoxyribose sugar, a nitrogenous base and a phosphate group. The nitrogenous bases found in DNA are Adenine, Thymine, Cytosine and Guanine. In DNA base pairing, Adenine pairs with Thymine while Guanine pairs with Cytosine. The structure of a DNA double stranded helix is like a ladder in which the bases form the steps or rungs while the phosphate group and deoxyribose sugar form the phosphodeoxyribose backbone. Deoxyribose is a pentose, a sugar with five carbon atoms.
The two complementary base pairs in DNA are adenine (A) with thymine (T), and guanine (G) with cytosine (C), which are connected by hydrogen bonds and critical for passing genetic information during cell division.
Explanation:The two complementary base pairs of DNA are adenine (A) with thymine (T), and guanine (G) with cytosine (C). These base pairs form the ladder-like structure of the DNA molecule. Adenine and thymine are connected by two hydrogen bonds, while guanine and cytosine are connected by three hydrogen bonds. This pattern of base pairing ensures that the genetic information is accurately passed on during cell division (mitosis). The base pairs are stacked within the DNA double helix structure, which was proposed by Watson and Crick, and they are stabilised by hydrogen bonds in a specific arrangement where a purine (A or G) pairs with a pyrimidine (T or C), ensuring the uniform diameter of the helix.

Meiosis II is ______________________ division which produces _______________ nuclei in _____________________ cells for a total of __________________ nuclei.
Meiosis II is reduction division which produces four nuclei in 4 haploid cells for a total of four nuclei.
Explanation:
Meiosis 2 is the second phase of meiosis in which each diploid cell gives 2 haploid cells forming four haploid cells. It takes place in eukaryotic cells in gametes or germ cells. Sister chromatids separate in meiosis 2.
It comprises following stages:
prophase II : nuclear membrane breaks down as chromosome condense. spindle fibres get formed and microtubules prepare to grip chromosome.
metaphase II : The chromosomes are lined at metaphase plate.
Anaphase II: the sisters chromatids gets pull apart.
telophase II : nuclear memebrane is formed around each pair of chromosomes, decondensation of chromosomes occur and cytokinesis follow making four haploid cells.
Meiosis II is the division that produces haploid nuclei in four cells, resulting in a total of four haploid nuclei.
Meiosis II is the second stage of meiotic cell division, following meiosis I. It is a type of cell division that occurs in sexually reproducing organisms to produce haploid gametes. During meiosis II, the primary objective is to further reduce the chromosome number in each cell, ensuring that the resulting gametes are haploid.
Meiosis II involves the separation of sister chromatids, which were produced during meiosis I. This separation process occurs in four daughter cells, each with half the number of chromosomes as the original parent cell. Therefore, meiosis II is a division that produces haploid nuclei in haploid cells. In total, meiosis II produces four nuclei, each contained within a separate daughter cell.
The process of meiosis II is crucial for maintaining the haploid state of gametes, ensuring that when fertilization occurs, the resulting zygote has the correct diploid chromosome number. Additionally, meiosis II contributes to genetic diversity through processes such as independent assortment and crossing over during meiosis I, leading to unique combinations of genetic material in each gamete.

Answer:
Explanation:
Physical weathering, also known as mechanical weather, is the process of rocks and minerals on Earth's surface breaking down or dissolving as a result of water, ice, salt, plants, animals or changes in temperature. Physical weathering does not change the chemical composition of the rock, just cracks and crumbles it into smaller pieces. After a rock has weathered, erosion occurs, transporting bits and pieces away. Finally a deposition process deposits the rock particles in a new place.
Physical weathering by plants, wind, and ice rock fragments to their new location. Water flowing quickly Ice wedges numerous rocks break as a result of ice plant roots can spread.
