Answer: frig metamorphosis is complete

Explanation:

This is because in complete metamorphosis, frog develop from egg to adults. Metamorphosis refers to change of shape and growth in different stages of animals life cycle.

Frog mate in the rainy season.

There are four stages of frog metamorphosis and they are;

1 Egg : the female mate with the male and the male fertilizes the egg. The female releases the fertilized egg inside water , they egg are jelly like or cover with jelly covering.

2. Tadpole: the egg then hatched into tadpoles. The tadpoles live in water, it does not have lungs and limbs. It move like fish and uses gills to breathe. At this stage it starts developing hind limbs and later lungs. It has long tail

3. Froglet : At this stage, the lungs and the front legs develop. It floats above the water to breathe. The tail become shorter and it uses nutrients stored in the tail to feed or survive.

4. Adult : this is the final stage, the young frog leave water and start live on land, it's tail disappear completely and it's start feeding on insects.

Answer:

beaver dams smooth out water flow by increasing the area wetted by the stream. This allows more water to seep into the ground where its flow is slowed. This water eventually finds its way back to the stream. Rivers with beaver dams in their head waters have lower high water and higher low water levels.

Introduction

Plants have evolved different reproductive strategies for the continuation of their species. Some plants reproduce sexually while others reproduce asexually, in contrast to animal species, which rely almost exclusively on sexual reproduction. Plant sexual reproduction usually depends on pollinating agents, while asexual reproduction is independent of these agents. Flowers are often the showiest or most strongly-scented part of plants. With their bright colors, fragrances, and interesting shapes and sizes, flowers attract insects, birds, and animals to serve their pollination needs. Other plants pollinate via wind or water; still others self-pollinate.

Asexual Reproduction

Vegetative reproduction is a type of asexual reproduction. Other terms that apply are vegetative propagation, clonal growth, or vegetative multiplication. Vegetative growth is enlargement of the individual plant, while vegetative reproduction is any process that results in new plant “individuals” without production of seeds or spores. It is both a natural process in many, many species as well as a process utilized or encouraged by horticulturists and farmers to obtain quantities of economically-valuable plants. In this respect, it is a form of cloning that has been carried out by humanity for thousands of years and by plants for hundreds of millions of years. Sexual Reproduction and The Flower

The flower is the reproductive organ of plants classified as angiosperms. All plants have the means and corresponding structures for reproducing sexually. The basic function of a flower is to produce seeds through sexual reproduction. Seeds are the next generation, serving as the primary method in most plants by which individuals of the species are dispersed across the landscape. Actual dispersal is, in most species, a function of the fruit (a structural part that typically surrounds the seed).

Plants and sexual reproduction: Plants that reproduce sexually often achieve fertilization with the help of pollinators such as (a) bees, (b) birds, and (c) butterflies.

Sexual Reproduction in Gymnosperms

Gymnosperms produce both male and female gametophytes on separate cones and rely on wind for pollination.

image

Male and female gametophytes: These series of micrographs shows male and female gymnosperm gametophytes. (a) This male cone, shown in cross section, has approximately 20 microsporophylls, each of which produces hundreds of male gametophytes (pollen grains). (b) Pollen grains are visible in this single microsporophyll. (c) This micrograph shows an individual pollen grain. (d) This cross section of a female cone shows portions of about 15 megasporophylls. (e) The ovule can be seen in this single megasporophyll. (f) Within this single ovule are the megaspore mother cell (MMC), micropyle, and a pollen grain.

Female Gametophyte

The female cone also has a central axis on which bracts known as megasporophylls are present. In the female cone, megaspore mother cells are present in the megasporangium. The megaspore mother cell divides by meiosis to produce four haploid megaspores. One of the megaspores divides to form the multicellular female gametophyte, while the others divide to form the rest of the structure. The female gametophyte is contained within a structure called the archegonium.

Reproductive Process

Upon landing on the female cone, the tube cell of the pollen forms the pollen tube, through which the generative cell migrates towards the female gametophyte through the micropyle. It takes approximately one year for the pollen tube to grow and migrate towards the female gametophyte. The male gametophyte containing the generative cell splits into two sperm nuclei, one of which fuses with the egg, while the other degenerates. After fertilization of the egg, the diploid zygote is formed, which divides by mitosis to form the embryo. The scales of the cones are closed during development of the seed. The seed is covered by a seed coat, which is derived from the female sporophyte. Seed development takes another one to two years. Once the seed is ready to be dispersed, the bracts of the female cones open to allow the dispersal of seed; no fruit formation takes place because gymnosperm seeds have no covering.

Answer: The water cycle also known as the hydrolic cycle describes the always foward rotation above and below the surfaces of the earth. The mass of water on earths surface remains fairly consistant. However, the water splits up into diffrent groups, freshwater, saline water, ice, and atmospheric water. The water can travel between catorgories such as river to ocean or ocean to atmosphere through evaporation, condensation, precipatation, surface runoff and subsurface flow. When water go through these physical process it can change aswell such as being a liquid, solid,and gas. During evaporation it takes water from it surroundings and cools its enviromwnt,

Answer:

Thanks to light energy or chemical energy, the producers, which are on the base of the pyramid, produce their food. Then, the primary consumers eat the producers. The secondary consumers eat the primary consumers. Lastly, the tertiary consumers eat the secondary consumers. The producers process the residues from all the levels obtaining their food and starting the cycle again. Each level in the pyramid has the matter that the animals in the next level will consume. The animals digest the food and break it down into small components that the body uses as energy and for its structure.

The flow of energy from one level to the other is not efficient. Part of it is lost as heat or due to not good digestion. As a result, the energy transferring as we ascend in the pyramid is lower, making it impossible to continue the pyramid since there is not enough energy to nourish another level.

Explanation:

There is a loss of matter from one level to another since some are lost as fecal matter because it could not be processed. The same process happens with the energy from one level to the other. The energy decreases since a part is lost as heat, and the animal uses a part of it to stay alive. As a consequence of this decrease in energy, the higher levels receive less energy than the ones in the lower part of the pyramid.

The flow of energy from one trophic level to another within an ecosystem.  Part of it is lost as heat or due to not good digestion.

Biodiversity has three levels - ecosystem, species and genetic diversity. Therefore, Biodiversity can be defined as the variability among living organisms involving terrestrial, marine, and other aquatic ecosystems, genes and alleles in a species and their ecological complexes such as diversity within species, and between species of the ecosystems.

As a result, the energy transferred as we ascend in the pyramid is lower, making it impossible to continue the pyramid since there is not enough energy to nourish another level.

Explanation:

In the first step, the information in DNA is transferred to a messenger RNA (mRNA) molecule by way of a process called transcription. ... The mRNA sequence is thus used as a template to assemble—in order—the chain of amino acids that form a protein. Figure 2: The amino acids specified by each mRNA codon.

Answer:

This process is called protein synthesis, and it actually consists of two. The enzyme is ready to make a strand of mRNA with a complementary sequence of bases.

Answer:

C. Tapeworm and human.

Answer:

Explanation:

A. The role of promoter in eukariotic gene expression is It is to bind transcription factors that regulate transcription initiation. This molecule is so important because control the binding of RNA polymerase to DNA. The promoter region may be short or very long; the longer the promoter is, the more protein binding space is available. A negative regulatory molecule has the possibilty to inhibit transcription at the promoter because these molecules block the binding of RNA polymerase to the promoter region, thus not allowing the initiation of transcription, in some particular cases, the negative regulator binds to the lac repressor and will bind to the promoter in the same site where RNA polymerase would bind to.

B. Two process that occur during RNA processing are RNA splicing and 5′ capping, 3′. RNA splicing is a procces known for removing the introns from the pre-RNA and stuck back together the restant parts, exons. This process has as a goal form a mature mRNA that does not contain the intron sequences. RNA splicing has effect on variation of mRNA molecules because through a process called alternative splicing more than one mRNA can be made from the same gene. 

C. Even though they are not quite the same thing miRNA and negative regulatory molecules have the same role, which is inhibit the translation and silence genes. They regulate gene expression by binding to the 3'-UTR of their target mRNAs and destabilizing the mRNA and translational silencing, repressing protein production. Even so, under specific circumstances, miRNA can activate translation or regulate transcription.

Answer:

el ATP es la moneda energética que la célula utiliza para llevar a cabo diversas funciones metabólicas (incluida la reproducción)  

Explanation:

La adenosín trifosfato (ATP) es la principal fuente de energía para la mayor parte de los procesos celulares. La hidrólisis del ATP libera energía química almacenada en los enlaces de fosfato de la molécula, la cual es utilizada por la célula para llevar a cabo diversas funciones, incluida la reproducción. La hidrólisis de ATP genera en primera instancia adenosín difosfato (ADP) y un grupo fosfato libre (ortofosfato), esta es una reacción exergónica que libera una enorme cantidad de energía la cual es utilizada por la célula para llevar a cabo diversas funciones metabólicas incluyendo la síntesis de macromoléculas tales como, por ejemplo, proteínas del huso mitótico requeridas durante el proceso de división celular. El ADP también puede hidrolizarse para liberar energía, con la consecuente producción de adenosín monofosfato (AMP) y un segundo fosfato libre.
