compare and contrast prophase of mitosis and prophase of meiosis1?
Answer:
The homologous chromosomes pair together in prophase 1 of meiosis, but they do not during prophase 1 of mitosis. This is achieved by a process known as synapsis, where the similar chromosomes pair according to sequence similarity. The homologous chromosomes are held together by a protein structure known as the synaptonemal complex in a chromosome body known as a tetrad (because it contains 4 replicated chromosomes known as chromatids) or bivalent (if the organism is diploid). This pairing during prophase 1 of meiosis allows recombination to take place between the homologous chromosomes. This occurs early during prophase but the manifestation of recombination only becomes visible during the later stages of prophase 1 and in metaphase 1. Because the chromosomes adopt different structures during prophase 1 of meiosis, this stage is sub-divided into 5 stages: leptotene, zygotene, packytene, diplotene and diakinesis. It is during diplotene and diakinesis that the physical manifestation of recombination can be seen. This is the presence of chiasmata (chiasma, singular). These are the sites where recombination, or exchanges between homologous chromosomes, has taken place. By the end of prophase 1, it is only the chiasmata that holds the homologous chromosomes together. This constriction make the tetrads adopt a variety of structures, the shape of which depends upon the number of chiasmata formed. The tetrads stay in this conformation until metaphase 1. Synapsis, the formation of the synaptonemal complex, the formation of chiasmata does not take place during prophase 1 of mitosis and these processes represent the major differences between prophase of the two nuclear divisions.

Scientists build models based on what they know from previous research to derive testable hypotheses.Independently, both Watson and Crick and their competitor Linus Pauling constructed an incorrect triple-helix model with the nitrogenous bases arranged so they were on the exterior of the molecule and the phosphate groups on the interior. What evidence caused Watson and Crick to revise their model (CHOOSE 2)
Answer:
Hello. You didn't show the answer options, but we can consider that Watson and Crick revised the DNA model after seeing DNA images taken through Franklin's x-ray and by observing the pairing of the nitrogenous bases.
Explanation:
For a long time it was believed that the DNA molecule had 3 strands, instead of two, however this information was inaccurate and although defended by some scholars it was somewhat controversial and showed the need for further investigation. With that in mind, Watson and Crick decided that it was necessary to evaluate DNA in a three-dimensional way and therefore, they obtained x-ray images of DNA molecules, taken by Franklin. In these images, it was possible to notice that the DNA had two strands, instead of three. To prove this discovery, Watson and Crick analyzed the nitrogenous bases discovered by Chargaff and the way they were paired, coming to the conclusion that the DNA had two strands.

Which statement below correctly describes the steps after fertilization in a plant?
A. The pistil containing the egg developes into a seed.
B. The ovary containing the egg developes into a fruit.
C. The stamen containing the egg developes into a seed.
D. The sepal containing the egg developes into a seed.
Answer: I think it's A or B, but make what you will from that :)
Explanation:
Sexual reproduction in plants occurs when the pollen from an anther is transferred to the stigma. Plants can fertilize themselves: called self-fertilization...When the ovules are fertilized, they will develop into seeds.
The statement below correctly describes the steps after fertilization in a plant: The ovary containing the egg develops into a fruit, which is in Option B, as the egg within the ovary begins to grow and develop into a seed after fertilization.
What is the importance of seed fertilization?Seed fertilization is the process by which a sperm from the male gametophyte (pollen) combines with an egg within the female gametophyte and usually occurs within the ovary of a flower and after fertilization, the zygote begins to divide and differentiate.
Hence, the statement below correctly describes the steps after fertilization in a plant: The ovary containing the egg develops into a fruit, which is in Option B, as the egg within the ovary begins to grow and develop into a seed after fertilization.

What is the likely effect of removing the wildcat on the population of ows and rabbits.
Think all the way down to the mouse.
PLZ HELP
Answer:
Rabbits would survive because there's 1 less predator preying on them, therefore they will reproduce more rabbits and rabbits will overpopulate. And the same thing will happen with the mice, therefore the owls will have less competition over food and their population will grow.

Select which option correctly Identifies if the following cross section of a stem is a monocot or a dicot and explains the correct reason why.
A. dicot because the vascular bundles are arranged randomly
B. monocot because the vascular bundles are arranged randomly
C. monocot because the vascular bundles are arranged in a pattern
D. dicot because the vascular bundles are arranged in a pattern
Answer: The following cross section of a stem is a monocot because the vascular bundles are arranged randomly. Correct option is B.
Explanation:
The flowering plants form the largest group in the plant kingdom. They are more highly evolved than gymnosperms because they have an abundance of water and food conducting vessels known as the VASCULAR BUNDLES..
The angiosperms are grouped into two namely:
---> Dicotyledons and
--> MONOCOTYLEDONS: These are the most advanced plants. They tend to be more efficient and specialised because they have fewer parts. As such they show a very high degree of adaptation to their environment. The VASCULAR BUNDLES which is defined as the conducting vessels (transport system) made up of xylem and phloem, are arranged randomly. The xylem is the water conducting tissue which also had a strengthening function while the phloem is the transports organic molecules ( food). The vascular bundles are scattered because they lack cambium and therefore do no undergo secondary growth.

If Earthquake X measured 1 and Earthquake Y measured 3 on the Richter scale, then
A. Earthquake Y had three times the ground motion of Earthquake X.
B. Earthquake Y had ten times the ground motion of Earthquake X.
C. Earthquake Y had 100 times the ground motion of Earthquake X.
D. None of the above
Answer: C. Earthquake Y had 100 times the ground motion of Earthquake X.
Explanation:
The Richter Scale is used to measure the intensity of earthquakes by comparing them to each other. There are 10 levels to the Richter Scale and each level is 10 times more intense than the last level.
If earthquake X measured 1 on the scale and earthquake Y measured 3, then Y was (10 * 10) times the intensity of X thereby placing Y at 100 times the intensity and ground motion of earthquake X.

Most organisms never fossilize, leaving holes in the fossil record.
E)
Because marine fossils are prevalent, this can lead people to believe they
were more dominant than they actually were
The limitation of using the fossils as evolutionary evidence should be plate tectonics, it never fossilizes, and marine fossils should be prevalent.
What is evolutionary evidence?
The evidence for evolution should be found at all type of levels of organization in living things and in the extinct species we aware of fossils.

7. Chemotrophs
Answer:
a. mixotrophs
b. autotrophs
c. syntrophs
d. phototrophs
e. heterotrophs
f. chemolithotrophs
g. chemotrophs
Explanation:
Autotrophs are organisms that can synthesize their own food using carbon dioxide (CO2) and water (e.g., algae, cyanobacteria, plants, etc). Syntrophs are organisms that utilize products from other organisms (e.g., mites that consume human dead-skin). Phototrophs are organisms that synthesize their own food by using the energy provided by sunlight (e.g., green plants). Heterotrophs are organisms that cannot synthesize their own food, obtaining energy and nutrients by consuming other organisms (e.g., animals). Mixotrophs are flexible organisms that obtain their food by using a mix of different sources of energy and carbon. Protists that combine autotrophy and heterotrophy are considered mixotrophs. Chemotrophs are organisms that obtain energy by the oxidation of electron donors from the environment, by using both organic sources (chemoorganotrophs) and inorganic sources (chemolithotrophs). Examples of chemolithotrophs include sulfur/iron-oxidizing bacteria, while chemoorganotrophs include the most known bacteria and archaea.

Explanation:
types of adaptation and explain
Answer:
The three basic types of adaptations, based on how the genetic changes are expressed, are structural, physiological and behavioral adaptations. Most organisms have combinations of all these types.
Explanation:
Living things are adapted to the habitat they live in. This is because they have special features that help them to survive. The development of these special features is the result of evolution due to gene mutation. These mutations aid in the survival and reproduction and passes on from one generation to the other.
Answer:
Behavioural-Physiological-Structural
Explanation:
Behavioural - responses made by an organism that help it to survive/reproduce.
Physiological - a body process that helps an organism to survive/reproduce.
Structural - a feature of an organism's body that helps it to survive/reproduce.

6.) State the principle of dominance? I
Answer:
Please find the answer below
Explanation:
According to the convener, Gregor Mendel, the law of dominance states that one allele of a gene called DOMINANT ALLELE possess the ability to mask the phenotypic expression of another allele called RECESSIVE allele.
This law explains that in a heterozygous state of a gene, the dominant allele will always be expressed over the other. For example, in the trait of height, if T is tall and dominant, it will mask the allele of the other phenotype.
