Answer:
The correct answer is -
O2 - through the stomata
Glucose - through the phloem in the veins
H2O- through stomata
Explanation:
In the process of photosynthesis, plants capture light energy to initiate a chemical reaction that uses CO2 and H2O as reactants and converted them into oxygen and sugar or glucose as products. Thus, oxygen and glucose are the products form in photosynthesis.
These products are carried through various paths to the new location to get utilized. Glucose is carried by the phloem in the veins out to the plant whereas oxygen and water diffuse into the environment through stomata.

Describe the difference between gene mutations and chromosomal mutations, including:
- What are they?
- How do they occur, including their types?
- When will they result in a change in the phenotype of offspring?
Explanation:
Genetic alternations include chromosomal abnormalities and gene mutations. Chromosomal abnormalities generally arise during cell division. ... Gene mutations are permanent changes in DNA gene sequence. They can arise during normal DNA replication or in response to environmental factors.
Answer:
When a gene mutation occurs, the nucleotides are in the wrong order which means the coded instructions are wrong and faulty proteins are made or control switches are changed. The body can't function as it should. Mutations can be inherited from one or both parents. They are present in the egg and/ or sperm cells.
What type of mutation can affect offspring?
The only mutations that matter to large-scale evolution are those that can be passed on to offspring. These occur in reproductive cells like eggs and sperm and are called germ line mutations. No change occurs in phenotype. Some mutations don't have any noticeable effect on the phenotype of an organism.

What kind of mutation would occur if a sequence of DNA is changed from ATCGGCTTAACG to ATCGGCTAAACG?
Answer:
Base substitution mutation
Explanation:
Mutation is the alteration or change that occurs to the sequence of a gene caused by a mutagen (chemicals) or spontaneously-induced. Depending on how the mutation occurs, it is of different types. The mutation shown in this question is as follows:
ATCGGCTTAACG to ATCGGCTAAACG
This type of mutation is called SUBSTITUTION MUTATION. Substitution mutation is a type of mutation that involves the replacement of one or more nucleotide base by another. In this original sequence; ATCGGCTTAACG, the eight base T was replaced by base A in the sequence, hence, it is a substitution mutation.

A. Breeding tomatoes to increase fruit size
B. Crossing 2 plants w desirable traits
C. Inserting genes from one plant into another
D. Returning bred plants to their natural habitat
Answer:
b
Explanation:
they chose the best tomatoes to make even better ones
Breeding tomatoes to increase fruit size is an example of selective breeding. Therefore option A is correct.
Selective breeding, also known as artificial selection, involves the intentional breeding of plants or animals to promote desired traits. The process typically involves selecting individuals with specific characteristics and breeding them to pass on those traits to the next generation.
In the given options, breeding tomatoes to increase fruit size is an example of selective breeding. By carefully selecting tomato plants with larger fruits and allowing them to reproduce, breeders can gradually enhance the fruit size of future generations.
This process relies on natural genetic variation within the tomato population and human intervention to guide the breeding process toward the desired outcome.

Answer:20
Explanation: Because when you divied 240 by 12 you get 20.
240/12=20
Answer:
20m/s
Explanation:
Speed is equal to distance/time. Since we know that the distance is 240m and the time taken to travel 240m was 12 seconds, we can divide them 240/12 and once we do this we can get our final answer of 20m/s.

Do you think the human species is part of the Earth’s ecosystem?
Answer:
I think that humans would be part of the ecosystem because we produce carbon dioxide for plants, and without carbon dioxide, plants couldn't function. (This is just my opinion on the matter, but if this was a test question, I'd say yes.)
Explanation:
Answer:
Hmmm that's a tough question. In my opinion I believe that they are because they some of us choose to have a role in the ecosystem by helping the Earth become more "green". Maybe think about this, how did we end up here on Earth? (This might go against your science class but we ended up here because God created us all.)

The gecko is a reptile that has the amazing ability to climb smooth surfaces - even glass. Recent discoveries indicate that geckos stick to smooth surfaces via van der Waals interactions between septae on their feet and the smooth surface. When not selling car insurance, geckos climb smooth surfaces.
a. How is this method of stickiness advantageous to the gecko over covalent interactions?
b. Given that van der Waals forces are among the weakest molecular interactions, how can the gecko's feet stick so effectively?
Answer:
a) This method of stickiness is advantageous over covalent interactions because it is weak and easily reversible.
b) The feet are equipped with millions of septae which collectively produce a synergistic effect that produces a powerful adhesive effect.
Explanation:
Geckos have their feet studded with tiny hair-like substances called septae, and these substances interact with the surfaces on which the Gecko climbs using weak van der Waals forces to produce stickiness.
a) The van der Waals interactions for the purpose of climbing is of more advantage over the covalent method of interaction because climbing involves a repetitive action of adhesion to the surface and destruction of such adhesion, and this involves the creation and the breaking of the bonds between the two surfaces easily. van der Waals forces being easily broken helps to achieve effective climbing. If the method of interaction is with a comparatively strong bond, the speed of creation and destruction of such bond is reduced, and the effectiveness of climbing is reduced.
b) Although van der Waals forces are weak forces, each foot of the wall Gecko has millions of septae that each create a van der Waals interaction, and the collective interactions produce a powerful adhesion causing the feet to stick effectively.
how is the law of mendelian inheritance violated in down's syndrome
Answer:
According to the Law of segregation presented by Mendel, each gamete receives just one copy of every allele randomly. Normally all the cells follow the Mendelian inheritance.
In Down's syndrome, an individual gets 3 copies of a chromosome instead of the normal chromosome pair. This is also known as trisomy 21. It does not follow the law of segregation of Mendelian inheritance as it gets three instead of two.
A variety of opium poppy (Papaver somniferum L.) having lacerated leaves was crossed with a variety that has normal leaves. All the F1 had lacerated leaves. Two F1 plants were interbred to produce the F2. Of the F2, 249 had lacerated leaves and 16 had normal leaves. Give genotypes for all the plants in the F1, and F2 generations. Explain how lacerate leaves are determined in the opium poppy. (Section 5.2)
Answer:
The correct answer is-
F1 - AaBb (lacerate)
F2 - A_B_; A_bb; and aaB_ (lacerate)
- aabb (normal)
2. Two genes, with a dominant allele at either or both loci.
Explanation:
The given information gives THE following data:
Dominant: Lancerate leaves - AABB
Recessive: normal leaves - aabb
F1 has - all Lacerated leaves - AaBb
F2 by selfing F1:
AB Ab aB ab
AB AABB AABb AaBB AaBb
Ab AABb AAbb AaBb Aabb
aB AaBB AaBb aaBB aaBb
ab AaBb Aabb aaBb aabb
Here, 15/16 = lacerate which is 0.94 which is equal to the value of lacerate given in the question - 249/265 = 0.94
And normal 1/16 = 0.062 is almost same as 16/265 = 0.060
Thus, the genotypes of -
F1 - AaBb (lacerate)
F2 - A_B_; A_bb; and aaB_ (lacerate)
- aabb (normal)

Ducks are aquatic birds. Their feet are webbed and this trait makes them fast swimmers. Biologists believe that ducks evolved from land birds, which did not have webbed feet. How could this have happened
Answer:
Random chance mutations led to the webbed feet trait in ancestral land birds, conferring them an adaptive advantage. Birds that inherited the beneficial random mutations associated with the webbed feet trait had more chances to survive and reproduce, passing this trait to the next generations.
Explanation:
Mutations are ramdom changes in the nucleotide sequence of the genome of a particular organism. In general, mutations are deleterious, but mutations may occasionally be beneficial in certain environments. A beneficial mutation must be associated with one or more phenotypic traits capable of conferring an adaptive advantage in a certain environment, thereby the individuals carrying the mutation have more chances to reproduce and survive. In this case, one or more beneficial mutations associated with the webbed feet trait passed to the next generations, increasing their frequency in the population.

Inversion of DNA sequences within chromosomes is a common process in evolution. The following gene arrangements in a particular chromosome are found in four different species: First sequence: STUVWX Second sequence: UVXTSW Third sequence: UVWSTX Fourth sequence: SWVUTX Assuming that the arrangement in the first sequence is the ancestor/reference arrangement, in what evolutionary order did the four species arise, such that the fewest number of inversions occur between each species (place the first sequence as the earliest species in your ordering)2341
Answer:
The correct answer is - 1, 4, 3, 2.
Explanation:
It is given that the first sequence represents the earliest or ancestor species therefore, the first sequence would be - STUVWX
After the inversion, the highlighted sequence of the first sequence STUVWX gives rise to the second sequence as:
STUVWX
SWVUTX
Thus the second sequence after Ist inversion would be SWVUTX
2nd inversion, Third sequence:
SWVUTX
UVWSTX
Thus the third sequence after 2nd inversion is UVWSTX
3rd inversion, fourth sequence:
UVWSTX
UVXTSW
Thus, the fourth sequence after 3rd inversion is UVXTSW

Which statement describes the general relationship between the temperature and the absolute brightness of main sequence stars?
As temperature decreases, absolute brightness increases.
As temperature decreases, absolute brightness remains the same.
As temperature increases, absolute brightness increases.
As temperature increases, absolute brightness remains the same.
Answer:
As temperature increases, absolute brightness increases
Explanation:
As temperature increases, absolute brightness increases
As temperature increases, absolute brightness increases. Therefore, option (C) is correct.
What is absolute brightness?Absolute brightness, also known as absolute magnitude, is a measure of the intrinsic luminosity of a star, which is its total energy output per unit of time. Absolute brightness is defined as the brightness a star would have if it were placed at a standard distance of 10 parsecs (32.6 light years) from Earth. This standard distance allows astronomers to compare the luminosity of stars with different distances from Earth.
Absolute brightness is an important measure for astronomers because it helps them determine the true luminosity and size of a star. It also helps astronomers classify stars based on their luminosity and temperature, which is related to their evolutionary stage. For example, main sequence stars, which are stars in the process of burning hydrogen to helium, are classified based on their temperature and absolute brightness
