1. The contour interval is 20.
Explanation:
On the map we can see a relief that is depicted with contour lines. The contour lines tend to be very close to each other in general so we can safely make the assumption that the relief is relatively steep, though in accordance to the elevations it is not a high one, but instead the highest points are actually hills.
From the numeric markings on the contour lines we can see the numbers 100, 200, 300, and in between them there are four contour lines. Since the difference in elevation in between every fifth contour line is 100, if we divide that number by the number of contour lines from one thicker contour line to another, which is five, than we get a value of 20, meaning that that is the contour interval.
2. and 3. A has an elevation of 80, B of 60, W between 301 and 319, X between 21 and 39, and Y of 400.
Explanation:
The contour interval is 20 on this map, so with the values we already have as marked on every fifth contour line, as well as the additional contour elements on the map or better reading of it, we can relatively easily establish the value of any point. We have five points in question, some being on the contour lines themselves, while some inside of them, meaning that for the ones on the contour lines we can give an exact value, while for the one inside we can give approximate value.
The points A, B, and Y are all marked on contour lines. A is on the contour line just below the one marked with 100, so minus 20 means that it has a value of 80. The point B is on the second contour line below the one marked 100, so minus 40 means it has a value of 60. Point Y is marked on a main contour line which is not marked, but it is the first thick one after the one marked with 300, so 100 plus means it has an elevation of 400.
Points W and X are marked inside the contour lines, so we can just give a range of value for them. Point W is marked above the contour line marked with 300 and there is no next contour line. Since the contour interval is 20, it means that this point can have value ranging from 301 to 319. Point X is marked below the contour line with a value of 40 and there is no other contour line below, meaning that the value can be in the range of 21 to 39.

Final answer:
The pituitary gland initiates puberty and releases LH and FSH, which stimulate the ovaries and testes to produce sex hormones, regulating gamete production. This leads to the production of a zygote when a sperm fertilizes an egg.
Explanation:
The gland that initiates puberty and releases hormones is the pituitary gland. During puberty, the pituitary gland secretes hormones like luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which stimulate the ovaries and testes. In response, the ovaries produce hormones such as estrogen and progesterone, and the testes produce testosterone. These hormones regulate the production of gametes, which are sperm in males and eggs (oocytes) in females. Egg production is a complex process that begins before birth and is arrested during meiosis until puberty, at which point it continues with each menstrual cycle, leading to the release of one egg during ovulation.
Male and female reproductive systems work together to produce a zygote, the initial cell formed when a sperm cell from the male merges with an egg cell from the female. Key processes include the formation of sperm and eggs, their transportation to enable fertilization, and the subsequent implantation and development of the zygote into a new individual.

What is the relationship between cell division and growth?
Answer:
The relationship between cell division and cell growth is that cell division needs to occur for the cells to divide and grow individually.
Explanation:
cell division refers to the process by which the mother cells divides into two daughter cells and cell growth refers to the process by which the size of the cell increases as it grows. They are two different but important and interlinked processes in the cell cycle. They depend on each other as failure in one will lead to failure in the other process too. The cell needs to grow proper in order to divide and create more cells.
Cell division is essential for growth as it allows an organism to increase in size and develop new tissues and organs. The process involves the generation of two daughter cells with identical genetic material. The cell division cycle consists of interphase and the mitotic phase.
Explanation:Cell division plays a crucial role in growth. When cells divide, they generate two daughter cells with the same genetic material. This process allows an organism to increase in size and develop new tissues and organs. The cell division cycle consists of interphase, during which cells grow and DNA is replicated, and the mitotic phase, where the replicated DNA and cytoplasmic contents are separated to form new cells.

what is a derived character
Answer:
To an evolutionary taxonomist, recent common ancestors determine whether 2 species are in the same genus. Derived character. A trait that arose in the most recent common ancestor of a particular lineage and was passed along to its descendants. An example of a derived character is the loss of a tail, a trait that first appeared in an ancestor of apes and man.
A derived character is a trait present in an organism but not in its ancestral form. It is a novel feature that evolved, distinguishing it from other organisms. They are important in constructing evolutionary trees, mapping out relationships among organisms.
Explanation:A derived character is a trait or characteristic that is present in an organism or species, but was not present in its ancestral form. It is a novel feature that evolved in an organism or lineage and thus distinguishes it from other organisms or lineages. An example of a derived character could be the opposable thumbs in humans that were not present in our early primate ancestors.
These characteristics are crucial in the study of evolutionary biology, as they help in constructing evolutionary trees, also known as phylogenetic trees. These trees map out the evolutionary history and relationships among different organisms, and a derived character is often used as a key piece of evidence in these diagrams.

When excess sugar is produced in a plant , the plant will
Answer:
Store it as starch
Explanation:
When a plant produces too much sugar during photosynthesis, it is transported through the phloem and is stored as starch in the roots. It can then be turned back into sugar when the plant needs it.
A plant with excess sugar will store it in the form of starch or glycogen in its tissues which can be used for energy later. The sugars are transported from where they are produced (sources like leaves) to where they are needed (sinks like roots and fruits) across the plant.
Explanation:When a plant produces excess sugar, it has mechanisms in place to utilize this surplus. The sugar serves as a vital source of energy, critical not only for immediate physiological processes but also for the plant's growth and maintenance. In conditions of high light and temperature, such as in C4 plants like maize and sugarcane, the production of sugar can be significantly higher when compared to C3 plants.
These sugars generated via photosynthesis in the leaves, which act as sugar sources, are allocated across the plant body to areas known as sugar sinks. Sinks are parts of the plant such as roots, stems, and developing fruits and seeds that need external sugar supply to meet their energy requirements. When reserves are abundant, excess sugars can be stored in the form of compounds like starch or glycogen, which provide a reservoir of energy that the plant can draw upon in times of scarcity or during the night when photosynthesis is not possible.
Explain the process of sexual reproduction in angiosperms.
Answer:
Process of sexual reproduction in angiosperms: There are two processes which are involved during sexual reproduction i. e. Pollination and fertilization. In pollination, the pollen of stamen falls on the stigma of carpel where they make a tube towards ovary where ovule is present. When the pollen reaches the ovary and fuses with ovule, it produces zygote which turns into seed, this process is called fertilization.
Angiosperms are the flowering plants that produces offspring by the process of se-xual reproduction.
Se-xual reproduction in angiosperms:The form of reproduction in which genetic material is required from both the parents is known as se-xual reproduction. The parent plants possess female and male se-x cells known as gametes. The male and female gamete combine to give rise to offspring by the process of fertilization.
The se-xual reproduction in angiosperms or the flowering plants takes place by the process of pollination. The flowers comprise female se-x organs known as pistils and the male se-x organs known as stamens. The part of the stamen, which comprise pollen is known as anther. The pollen is required to move to the part of the pistil known as stigma.
Plants can either cross-pollinate or self-pollinate. Pollinators refers to the animals or the agents that carry the pollens to the stigma in the plants. After pollination, the next step is fertilization. After reaching the pistil, the pollen requires to fertilize and egg within the stigma, this egg is known as ovule. The process of fertilization give rise to the fruits that comprise seeds.
Thus, in the angiosperms, the process of se-xual reproduction in order to produce the offspring.

a) which trait is dominant?
b )what must be the genotypes of the parents ?
Answer: A) Black trait is dominant
B) The genotypes of the parents must be Bb
Explanation: Let B represent the allele for black colour and b represent the allele for white colour. If the offspring between 2 black mice show the ratio of 3 black mice to 1 white mouse, it then means that the two parents are heterozygous for black colour, that is each of them have one allele for black colour (B) and one allele for white colour (b). They both have a genotype of Bb.
Bb x Bb = BB, Bb, Bb, and bb.
This means 1BB : 2Bb : 1bb
BB is black, Bb is black while bb is white which gives a ratio of 3 black mice to one white mouse. For Bb to manifest as black, it means that B is dominant to b.

what adverse effect will felt on ecosystem if there is more producers than consumers
Final answer:
An imbalance with more producers than consumers in an ecosystem can lead to oxygen depletion, disrupt the food web, and cause a shortage of nutrients due to overabundance of producers and insufficient herbivory.
Explanation:
In an ecosystem, the balance between producers and consumers is critical for its health and sustainability. If there were more producers than consumers, several adverse effects could become apparent. For instance, without enough consumers to eat them, plants or grasses in the ecosystem might become overly abundant, potentially leading to oxygen depletion which can cause die-offs in aquatic systems. This imbalance can disrupt the food web and may result in a pyramid of predators, stressing that predators are usually fewer than producers for efficient ecosystem function. Additionally, the excessive multiplication of producers, without sufficient consumption by herbivores, could cause a shortage of nutrients for the producers themselves, eventually affecting the entire system negatively.
