Answer:
Hydrophobic
Explanation: The phospholipid has a chagred head (Phosphate region) and hydrophobic tails. Lipids are usually nonpolar and hydrophobic. That is why the tails are oriented towards the interior of the membrane.
The two parts 3 and 4 in the region B of the phospholipid model are 3- saturated fatty acids and 4- unsaturated fatty acids.
What is phospholipid model ?
Phospholipids are a class of lipids having significant role in the construction of cell membranes. It is composed of a hydrophilic head with a phosphate group and a hydrophobic tail with fatty acids end.
The fatty acids present in the phospholipid bilayer , are of two types, Saturated and unsaturated. Fatty acids chains without any double bonds or triple bonds are called saturated fatty acid.
Whereas, fatty acid chain with double bonds or triple bond are called unsaturated fatty acids. These two fatty acids chain creates the hydrophobic tail of the phospholipid bilayer.
Hence the region marked as B is saturated and unsaturated fatty acids.

An ecologist is studying Dunaliella salina a single celled algae in a local pond. The pond is located near a construction site and the ecologist wants to know what affect, if any, the construction site is having on the pond, as there has been a steady decline in the Dunaliella salina population. In order to complete their study the ecologist would like to examine the organelles inside Dunaliella salina. If they would like to examine the inner structure of the chloroplasts of an already dead Dunaliella salina, what microscope would be best suited for this task? *
A.)dissecting microscope
B.)compound microscope
C.)scanning electron microscope
D.)transmission electron microscope
Answers
In the given scenario, to see the structures of chloroplast scientists can use a transmission electron microscope. The correct option is D.
What is transmission electron microscope?Transmission electron microscopes (TEM) are microscopes that visualize specimens and basically create a much higher magnification of an image using an electron particle beam.
TEMs have the ability to magnify objects up to 2 million times.
Transmission electron microscopy (TEM) is a popular method for examining the ultrastructure of organelles.
TEM generates high-resolution pictures by passing electrons through an ultrathin segment of a sample and magnifying the resulting image with a series of lenses.
The electron beam of the TEM penetrates thin slices of biological material, allowing the study of individual components of cells and organelles.
Thus, the correct option is D.

Which of the following best explains why matter must travel through cycles?
a
There is an unlimited amount of matter in the universe, so it can take on any form at
any time.
b
There is a fixed amount of matter in the universe, so it must take on different forms
at different times.
Answers
Elements flows within ecosystem in various ways. It is important for matter to travel through cycle as there is a fixed amount of matter in the universe, so needed to be recycled.
What is cycling of matter?Matter cycling is movement of matter from one form to another or from one place to another on the Earth, inside its ecosystems.
Matter is constantly cycling from place to place, and this can have both positive or negative effects. Matter also cycles naturally, or can be due to human activity.
As there are only finite number of nutrients on the Earth, so, it is necessary for them to be recycled in order to ensure the continued existence of living organisms.
Thus, option b is correct.

Explain why an increase in precipitation and in the number of nearby factories has a greater impact on the occurrence of the mari flowers than changes in temperature, length of day, and invasive species
Answers
Advanced rainfall during the growing period can lead to an improvement in the utilization of soil water, which is beneficial to root growth.While rain clearly affects food supply, it also can affect foraging behavior, reproductive and population growth rates, and competitive interactions in subtle ways that might be difficult for researchers to trace back to any particular sourceThe increase of precipitation and number of nearby factories has a greater impact on the occurrence of mari flowers because some types of precipitation has acid in it, and the acid has a high pH level. All of those chemicals have higher pH levels than changes in temperature.

As you all know that living is a synonym for biotic, as both discuss the measures of life. It significantly includes plants, animals, humans, predators, etc.
What is biotic?Biotic may be defined as something that is closely related to living organisms or something that is directly derived through the action of living organisms.
As compared to living, biotics may not always be alive, but it talks for a long period. Biotic is something that has once lived or emanated from something living.
Examples like plants, animals including humans are categorized under the category of living, while products such as rubber, latex, cow dung, paper, etc are biotic products that are not living.
