Answer:

undergo irreversible repression

Explanation:

Cellular differentiation refers to the process by which one cell and/or cell population divides and differentiates into more specialized cells. During cell fate differentiation, epigenetic marks modify chromatin structure in order to hamper the accessibility of the transcriptional machinery and transcriptional factors to different genes, which are irreversibly repressed. These epigenetic marks include DNA methylation and histone modifications (e.g., histone acetylation, histone methylation, etc). For example, it has been shown that DNA methylation and histone H3 lysine 27 tri‐methylation (H3K27me3) are epigenetic repressive marks on genomic regions that play a major role in gene expression programs during cell fate differentiation.

Answer:

clastic sedimentary rock are made up of pieces of pre-existing rocks. pieces of rock are loosened by weathering, then transported to some basin or depression where sediment is trapped. if the sediment is very deeply, it becomes compacted and cemented, forming sedimentary rock.

Explanation:

Hope this helped Mark BRAINLEST!!!!

Answer:

Sedimentary rocks are the product of 1) weathering of preexisting rocks, 2) transport of the weathering products, 3) deposition of the material, followed by 4) compaction, and 5) cementation of the sediment to form a rock. The latter two steps are called lithification. A sediment is a particle of solid, loose pieces of rocks (in the form of sand, silt, clay, and gravel), or the remains of living organisms. Sediment is material that has been eroded, transported and deposited by wind, running water, waves, and ice in a place.

These rocks can also form from by the evaporation of seawater, or the settling of the remains of organisms in a water body. Sediment can become compacted, cemented and are foundin layers. Sedimentary rock is often found in layers.

Sedimentary rocks are formed on or near the Earth's surface, in contrast to metamorphic and igneous rocks, which are formed deep within the Earth. The most important geological processes that lead to the creation of sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification.

Answer:

It has crust and trough.

Explanation:

The oceans movements along the shore called waves because it has crust and trough just like waves and vibrates about its mean position. A crest is a higher point of wave whereas trough is the opposite of a crest and lowest point of a wave. Ocean waves is similar to sound and light waves because both waves travel as up and down vibrations and the energy present in these wave travels in forward direction.

Answer:

En los seres vivos acuáticos el oxigeno es tomado del agua y penetra a la célula por el fenómeno de respiración branquial.

Explanation:

La respiración es el proceso mediante el cual los seres vivos obtienen oxígeno.  Es decir, la respiración implica el reemplazo del dióxido de carbono en los pulmones por oxígeno del aire, y puede ser pulmonar, branquial, traqueal o cutánea.

La respiración branquial es un tipo de respiración propia de la mayoría de los animales acuáticos y se lleva a cabo en las branquias, unas estructuras con forma de láminas que contienen vasos sanguíneos. Los animales acuáticos dispone de estos órganos que permiten absorber el oxígeno que se encuentra en el agua y eliminar el dióxido de carbono.

El agua que entra por la boca y circula por las branquias, donde el oxígeno es absorbido, pasa a la sangre y es transportado a todo el cuerpo donde se produce una respiración celular.

Es decir, en los seres vivos acuáticos el oxigeno es tomado del agua y penetra a la célula por el fenómeno de respiración branquial.

Answer:

1. Cinder cones

2. All of these

Explanation:

1. Cinder cones develop from explosive eruptions of mafic (heavy, dark ferromagnesian) and intermediate lavas and are often found along the flanks of shield volcanoes. The outside of the cone is often inclined at about 30°, the angle of repose (the slope at which the loose cinder can stand in equilibrium).

2. Volcanic Explosivity Index (VEI) is a numeric scale that measures the relative explosivity of historic eruptions. Volume of products, eruption cloud height, and qualitative observations (using terms ranging from "gentle" to "mega-colossal") are used to determine the explosivity value. The Volcanic Explosivity Index (VEI) was derived to catalogue the explosive magnitude of historical eruptions, based on the order of magnitude of erupted mass, and gives a general indication as to the height the eruptive column reached.

Answer:

Resistance plants increase in number whereas non-resistant plants decreases.

Explanation:

The environment of rain forest is suitable for the fungal growth because of the presence of humidity in the environment and we know that fungi needs moist places for its growth. These fungus attached on the leaves and takes nutrients from that plant that leads to the stunted growth and many cases death of the plant occurs. Some plants have no effect of this fungus due to the presence of resistance in them so if the fungus spreads in the whole forest so the plants which are prone to these fungal infections eliminated from that environment and resistant plants are increase in number.

Answer:

Part B

Many rain forest plants are prone to developing fungal infections on their leaves. Fungi can grow rapidly in moist environments, and a serious infection can kill plants. One rain forest plant species has a genetic variation that affects its leaf structure. The traits and the descriptions of the plant’s leaves are listed in the chart.

Explanation:

Answer: Each strand act as a template strand for another strand this way two strands are responsible for the production of two new strands. This way after the replication process two DNA molecules are produced.

Explanation:

S phase of the cell cycle is the synthesis phase of the cell cycle. This phase occurs after the interphase of the cell cycle. In this phase, the replication and synthesis of the DNA occur. The genetic material gets copied and doubled in this process before it enters into mitosis or meiosis. Each strand is utilized as a template strand for the synthesis of the complementary strand this way two molecules of DNA are produced. This way each cell contains a diploid set of chromosomes before it undergoes cell division into daughter cells in mitosis or meiosis.

Each strand act as a template strand for some other strand this manner strand is accountable for the manufacturing of new strands. In this manner after the replication system  DNA molecules are produced.

S phase of the cell cycle is the synthesis section of the cell cycle. This section happens after the interphase of the cell cycle. In this section, the replication and synthesis of the DNA arise. The genetic material receives copied and doubled on molecular this system earlier than it enters into mitosis or meiosis.

Each strand is applied as a  template strand for the synthesis of the complementary strand this manner molecules of DNA are produced. In this manner, every cell carries a diploid set of chromosomes earlier than it undergoes cell department into daughter cells in mitosis or meiosis.

S phase (Synthesis Phase) is the section of the cell cycle wherein DNA is replicated, taking place among the G1 phase and G2 phase. Since correct duplication of the genome is essential to a successful cellular department, the techniques that arise for the duration of the S-phase are tightly regulated and broadly conserved.

Hence it states that the DNA is being replicated during the S phase of the cell cycle, it copies each strand differently.

Answer:

The frequency of the non-taster phenotype among people of European descent is 49% or 0.49

Explanation:

Let us assume that the allele for tasting PTC is T, while that for not tasting PTC is t.

According to the Hardy-Weinberg equation : p² + 2pq + q² = 1

Also p + q = 1

Where p² is the frequency of individuals with the TT genotype for tasting PTC,; wow is the frequency of individuals with the heterozygous allele for tasting PTC, while q² is the frequency of the individuals with tt genotype expressed as the non-taster phenotype since the allele for tasting is dominant over that of the non-taster.

From the information provided 51% of people of European descent are tasters. Also, tasting PTC is dominant over non-tasting. This implies that individuals with TT genotype and Tt genotype will be phenotypically expressed as tasters.

Therefore p² + 2pq = 51% or 0.51

q² = 1 - p² + 2pq

q² = 1 - 0.51

q² = 0.49 or 49%

The frequency of the non-taster phenotype among people of European descent is 49% or 0.49

Getting to know the number and pattern of bones in limbs is important to understand the evolution of tetrapods.

---------------------------------------------------------

Fossils are animal and vegetable rests found in different strata of sedimentary rocks. Sedimentary layers deposit chronologically, so they are used to reflect history. These fossils turn to be very useful while dating ages and studing evolutive processes.

Fossils provide good information about the existing relationship between ancient and modern tetrapods. Limb structures between these organisms are relatively similar. However, they can change in the number of bones and their arrangement pattern, reflecting the changes that species suffered through evolution.

The pattern in which the composing bones are arranged in limbs is useful to study tetrapods evolution, from a common aquatic ancient -fish- to modern terrestrial and aquatic tetrapods.

By looking at the number of limbs and digits, and the bones' pattern involved in these structures, scientists could interpret how evolutive processes occurred.  Information about bones' density, length, and size, is also useful to understand the environmental pressures acting on the animals, and how the tetrapods managed to adapt.
