Could someone help me out with this easy question? I wasn’t in class today.

Answer:

El parasitismo ocurre cuando un individuo, el parásito, se beneficia de otro individuo, el anfitrión, mientras daña al anfitrión en el proceso. Los parásitos se alimentan de tejidos o fluidos del huésped y se pueden encontrar dentro (endoparásitos) o fuera (ectoparásitos) del cuerpo del huésped (Holomuzki et al. 2010).

Advancements in computer technology most directly influenced knowledge of wildlife and ecosystems by spreading information about them, about their role in ecosystems, their importance, etc.

Ecosystems consist of both living organism and non-living substances. Examples of ecosystems are the grassland ecosystem, the ocean ecosystem, the desert ecosystem, etc. In a grassland ecosystem, all organisms, such as plants, animals, and bacteria, work together in coordination. Different ecosystems have different wild lives . Example: In a forest ecosystem, there are tigers, elephants, lions, donkeys, etc.

They are affected by different human-made activities as well as by natural calamities such as earthquakes. The concerns about the changing ecosystem and its impact on wild life, such as the impact of climate change on them and global warming, are highlighted due to the advancements in computer technology. Activists and the general public spread awareness about them.

Hence, in this way, the advancements in computer technology help spread awareness among people about wildlife and the ecosystems .

Your answer is → compartment within the cell called a nucleus

In a cell, DNA would most likely be found inside the nucleus which is known as the controlling center of the cell.

DNA stands for Deoxyribonucleic acid. It is considered the most common genetic material of living organisms. The genetic information of a particular organism is encoded with these segments, known as DNA.

The process of transcription is initiated within the nucleus of the cell which transforms DNA into mRNA. It is known as the brain of the cell. Due to compartmentalization in eukaryotic organisms, a well-defined nucleus has appeared which helps in the transfer of genetic information from one generation to the next.

Therefore, the nucleus is the region where DNA is most likely found within the cell.

strobila or cone produce egg cell in non flowering plants

The organ in many nonflowering plants which produces an egg cell is the strobila or cone produce.

Nonflowering plants don't produce flowers; instead, they produce microscopic reproductive elements called seeds or spores that may be used to create additional plants that look just like them.

A shorter stem with several altered leaves bearing sporangia makes up strobili. Gymnosperms, like all seed plants, are heterosporous. Usually, different cones are used to carry the sporangia that produce the male microspores as well as female megaspores.

Nonflowering plants like ferns, mosses, etc other nonflowering plants have reproductive organs called antheridium and archegonium. The male gametophyte's primary source of sperm cells would be the antheridium (male gametes). Numerous sperm will be produced by the antheridium for fertilization.

Explanation:

What is biodiversity? Well, in simple terms, biodiversity refers to all the variety of life that can be found on Earth (plants, animals, fungi, and micro-organisms) as well as to the communities that they form and the habitats in which they live. But how is biodiversity connected to healthy ecosystems? Well, many factors can contribute to this question but  Biodiversity boosts ecosystem productivity where each species have an important role to play. With this in play we can see that it is healthy and keeps ecosystems safe.

Answer:

Like terrestrial biomes, aquatic biomes are influenced by a series of abiotic factors. The aquatic medium—water— has different physical and chemical properties than air. Even if the water in a pond or other body of water is perfectly clear (there are no suspended particles), water still absorbs light. As one descends into a deep body of water, there will eventually be a depth which the sunlight cannot reach. While there are some abiotic and biotic factors in a terrestrial ecosystem that might obscure light (like fog, dust, or insect swarms), usually these are not permanent features of the environment. The importance of light in aquatic biomes is central to the communities of organisms found in both freshwater and marine ecosystems.  

Explanation:

The ocean is categorized by several areas or zones (Figure 1). All of the ocean’s open water is referred to as the pelagic zone. The benthic zone extends along the ocean bottom from the shoreline to the deepest parts of the ocean floor. Within the pelagic realm is the photic zone, which is the portion of the ocean that light can penetrate (approximately 200 m or 650 ft). At depths greater than 200 m, light cannot penetrate; thus, this is referred to as the aphotic zone. The majority of the ocean is aphotic and lacks sufficient light for photosynthesis. The deepest part of the ocean, the Challenger Deep (in the Mariana Trench, located in the western Pacific Ocean), is about 11,000 m (about 6.8 mi) deep. To give some perspective on the depth of this trench, the ocean is, on average, 4267 m. These zones are relevant to freshwater lakes as well.

The ocean is the largest marine biome. It is a continuous body of salt water that is relatively uniform in chemical composition; it is a weak solution of mineral salts and decayed biological matter. Within the ocean, coral reefs are a second kind of marine biome. Estuaries, coastal areas where salt water and fresh water mix, form a third unique marine biome.

The intertidal zone, which is the zone between high and low tide, is the oceanic region that is closest to land (Figure 2). Generally, most people think of this portion of the ocean as a sandy beach. In some cases, the intertidal zone is indeed a sandy beach, but it can also be rocky or muddy. Organisms are exposed to air and sunlight at low tide and are underwater most of the time, especially during high tide. Therefore, living things that thrive in the intertidal zone are adapted to being dry for long periods of time. The shore of the intertidal zone is also repeatedly struck by waves, and the organisms found there are adapted to withstand damage from the pounding action of the waves (Figure 2). The exoskeletons of shoreline crustaceans (such as the shore crab, Carcinus maenas) are tough and protect them from desiccation (drying out) and wave damage. Another consequence of the pounding waves is that few algae and plants establish themselves in the constantly moving rocks, sand, or mud.

Answer:

Answer:

transform or changed

Explanation:

you can change matter from one stay to the next but you cant actually create it or completely destroy it

We perform a Chi-square analysis to find out if the difference between observed and expected is due to chance or not. In this example, 1) FD=1 / 2) X² = 2.22 / 3) Fail to reject the null / 4) 75.

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

Since a complete introduction to Chi-square was provided, we will proceed with the problem analysis.

1st Cross: Yellow   x   green

Parentals)  YY    x      yy

F1) 100% Yy, yellow

2nd Cross:  Yellow   x   yellow (From F1)

Parentals)    Yy    x     Yy

F2) 3/4 = 75% of the progeny is expected to be yellow

     1/4 = 25% of the progeny is expected to be green

We know from the data, that there are 1500 individuals in F2. So we can get the expected number of individuals from this data.

100 % of the progeny ----------------------- 1500 individuals

75 % yellow ------------------------------------X = 1125 individuals

25% green -------------------------------------X = 375 individuals

We assume the population is in H-W equilibrium, but we observe differences in what we expect to see and what we actually see. We want to know why.

Now we will make a table resuming information

                               Yellow                       Green

Observed                 1150                            350

Expected                  1125                            375

(Obs-Exp)²/Exp        0.555                         1.666

We can see that the table value is greater than the X² value, so there is not enough evidence to reject the null hypothesis.

The genotypes might be in equilibrium, and there might be independent assortment.

This results suggest that the difference between the observed individuals and the expected individuals is by random chances.

So now let us answer the questions,

1) Determine the degrees of Freedom of the phenotypic ratio for this genetic cross ⇒ DF = 2 - 1 = 1

2) What is the result of your Chi-squared analysis? ⇒ X² = 2.22

3) Do we fail to reject or reject the null hypothesis? ⇒

We Fail to reject the null hypothesis. There is not enough evidence to reject it.

4) If we flipped a coin 100 times. Which of the following is the minimum number necessary to achieve significance? 75 is the minimum number necessary to achieve significance
