Answer: The movement of continents changes wind patterns and ocean currents.

hope this helps!

Explanation:

The best statement that describe the effect of tectonic activity on climate change is that the movement of continents changes wind patterns and ocean currents.

Tectonic activities includes volcanoes, mountain building, earthquakes and many more.

Tectonic activities are common in plate boundaries where plates converge, diverge or transform.

As a result of the movement of these continental plate, tectonic activities occurs causing earth climate change

Therefore, the movement of this oceanic or continental plates changes the wind pattern and ocean current.

A heritable change in a person's genetic makeup is referred to as a mutation. Changes can be substantial or negligible. Chromosomes or chromosome parts may be lost, added, duplicated, or rearranged in significant alterations. Thus, option B is correct.

High-energy sources like radiation or chemicals in the environment can both result in mutations. They may also emerge on their own during DNA replication. The two main kinds of mutations are chromosomal abnormalities and point mutations.

Mutations can alter an organism's phenotype, which is its outward appearance, or they can have an impact on the way DNA encodes the genetic information (genotype). When mutations happen, they might kill an organism completely or only partially.

The likelihood that a gene mutation will cause an animal to be unable to produce the protein necessary for muscles to contract is that the animal will perish before producing any progeny.

Therefore, The animal will die before having any offspring.

Metaphase is a stage of mitosis in the eukaryotic cell cycle in which chromosomes are at their second-most condensed and coiled stage (they are at their most condensed in anaphase).

Answer:

1.) The atmosphere is an open system, with heat energy always escaping to space. Unlike the glass it absorbs 95% of the UV in the creation of ozone. This sounds insignificant, but one scientist argues variation in the 5 percent is the cause of warming.

2.) There are no winds in a greenhouse. In the greenhouse and in the atmosphere energy is partly transferred from the heated surfaces through collision between air molecules (conduction). However, in the atmosphere a large portion of that heat is transported vertically by rising air currents (convection), and also horizontally by advection or commonly wind. There are no winds in a greenhouse.

3.) Heat reduction in a greenhouse requires a physical change with a vent to let LW escape or a screen to block SW entering. Clouds are nature’s screen. However, they can block SW and LW, such that we have little idea how clouds work to modify temperatures

Explanation:

The basic idea of a greenhouse is that sunlight or shortwave (SW) energy passes through the glass and heats surfaces. The surfaces radiate that heat as longwave (LW) energy or sensible heat (heat you can feel). LW cannot pass through the glass, so is trapped and raises the temperature in the greenhouse; the glass acts like a one-way valve. A greenhouse is a closed system because the heat cannot escape unless artificially changed by opening vents or blocking sunlight. The glass supposedly represents the entire atmosphere. It also blocks 100 percent of the ultraviolet (UV) portion of the sunlight.

Some facts about Water erosion :

Water erosion is the detachment and removal of soil material by water. The process may be natural or accelerated by human activity. ... Water erosion wears away the earth's surface. Sheet erosion is the more-or-less uniform removal of soil from the surface.

Water and Wind Erosion (cause)

Water erosion is the removal of soil by water and transportation of the eroded materials away from the point of removal. Water action due to rain erodes the soil and causes activities like gully, rill, and stream erosion leading to the downstream effects of flooding and sedimentation.

Dominant and recessive genes

Explanation:

There is mutation of dominant genes

Prophase-I occurs over a long duration and involves several complicated changes in meiotic cell division. It is important because genetic recombineiion and variation in sexually reproducing organism occurs due to the events of this phase.

❈ Leptotene —

➥ The chromatin network opens out and threads become clear.

➥ The chromosomes are thin, slender and long.

➥ Chromosome number is diploid.

❈ Zygotene —

➥ Corresponding chromosomes become intimately associated.

➥ The process of pairing is known as synapse. It is so exact that pairing is not merely between corresponding chromosomes but between corresponding individual units.

➥ The chromosomes become shorter and thicker.

❈ Pachytene or Pachynema —

➥ The synaptic chromosomes become very intimately associated.

➥ The pair of chromosomes becomes short and thick.

➥ Crossing over occurs at this stage. Chiasmata are clearly seen.

❈ Diplotene —

➥ Homologous chromosomes start separating from one another.

➥ Chiasmata tend to slip out of the chromosomes. This is known as terminalisation of chiasmata.

➥ Chromosomes start separating out but the separation is not complete.

➥ Nuclear membrane and nucleolus start disappearing.

❈ Diakinesis —

➥ The bivalents condense further and get randomly distributed.

➥ The separation of paired chromosomes is almost complete.

➥ Terminalisation of chiasmata is almost complete.

➥ Nuclear membrane and nucleolus disappear.

Answer:

Pink. Incomplete dominance is a blending of phenotypes.

The flow of individuals in and out of a population introduces new alleles and increases genetic variation within that population. Mutations are changes to an organism's DNA that create diversity within a population by introducing new alleles.

Answer:

Autotroph

Explanation:

An autotrophic organism is any organism that is capable of synthesizing its own food either by using sunlight (photosynthesis) as an energy source or chemicals (chemosynthesis). An organism capable of photosynthesis must possess CHLOROPLAST (CHLOROPHYLL), which is responsible for capturing sunlight in the cell and also harbors the photosynthetic process.

According to this question, a newly discovered protist is said to have chloroplasts and vacuoles and moves using a flagellum. Due to the fact that this protist possess CHLOROPLAST organelle, it means it can perform photosynthesis, which is one of the ways an autotrophic organism synthesizes it's food. Hence, the organism is AUTOTROPHIC.

Answer:

Sexual

Explanation:

Sexual reproduction involves two parents and produces offspring that are genetically unique. During sexual reproduction, two haploid gametes join in the process of fertilization to produce a diploid zygote. Meiosis is the type of cell division that produces gametes.

Hope it helps

Answer: Sexual, I believe.

Explanation:

If it were Asexual, it'd only involve one parent. Mitosis has daughter cells have the same number of chromosomes as parent cells (heavy emphasis on cells as in plural cells.) And replication is just copying a cell.

Forgive me if I'm wrong!

The biological species concept tells us that organisms belong to the same species if they can breed to produce fertile and viable offspring. Speciation is therefore the development of reproductive isolation between individuals of an original population.

This can occur in 2 different ways:

1. Allopatric speciation. This is when speciation occurs due to some sort of geographic barrier separates a population into 2 groups. These two groups can then undergo genetic divergence, where each group grows increasingly dissimilar genetically due to random mutations and natural selection acting separately in each group, or from processes such as genetic drift. It is important to recognize that the lack of gene flow between these two groups contributes to the genetic divergence of the groups. Genetic divergence can lead to prezygotic and post-zygotic barriers which prevent production of fertile/viable offspring between the 2 groups. Each of these populations now represents a new species, whose gene pools are completely separate from one another.

2. Sympatric speciation. This is when speciation occurs without the presence of any sort of physical/geographical barriers. Truthfully, this is a much less common occurence. However, it is thought that sympatric speciation can occur as a result of strong divergent selection. Sympatric speciation may also occur as a result of a polyploid individual being introduced into a diploid population.

Isolation leads to speciation by preventing gene flow between 2 groups of an original population, allowing genetic differences between the groups to accumulate over time (via natural selection, genetic drift, etc.). Over time, the accumulation of these genetic differences may result in reproductive isolation between the 2 groups, causing these two groups to be committed to separate evolutionary paths.

Answer: So, how might speciation happen?

Explanation:

Speciation describes a situation where a population in a species becomes so different that it can no longer successfully interbreed with other populations of the ‘same’ species.
