Answer:
C
Explanation:
0.20-0.10=0.10
because the population was decreased
Answer:
Option C, 0.20 – 0.10 = 0.10
Explanation:
Total number of births taking place in an year is equal to 200.
Number of births per person is equal to
[tex]\frac{200}{1000} = 0.2[/tex]
Total number of deaths happening in an year is equal to 100
Number of deaths per person is equal to
[tex]\frac{100}{1000} = 0.1[/tex]
Net growth in population per person
Total number of births per person - total number of deaths per person
Substituting the given values in above equation, we get -
[tex]0.20 -0.10 = 0.10[/tex]
Hence, option C is correct

All ecosystems are affected by wildfires equally.
I belaive
the answer is true
The statement is true. All the ecosystems are affected by wildfires equally.
Explanation:Wildfire can be described as the uncontrolled fire when all the fauna and flora of the ecosystem is burned by the fire.Every ecosystem is consist of the living organism either in form of plants or animals. Plants and animals both are sensitive to fire and can be destroyed completely.For example a rain forest if gets fire, all the plants and trees will be burnt and the animals and bird inhibiting that forest will also be dead. As well as fire in desert also cause destruction.Because fire destroy the vegetative areas of ecosystems which are the food for other organisms in that ecosystem.In a population of humans, the frequency of straight hair is 34 percent. If straight hair is the recessive phenotype, what is the frequency of the homozygous recessive genotype? 17 percent 34 percent 66 percent 68 percent
34 percent fam I saw it on quizlet fyi thats where I get my answers and help on my work
Answer:
Option B, 34 percent
Explanation:
Given,
Frequency of straight hair [tex]= 34[/tex]%
Let the allele for straight hair be represented by "s" and the allele for any other hair type be represented by "S"
Here, S is dominant over s.
Thus, as per the Hardy Weinberg's equation
the frequency of a homozygous recessive genotype is represented by "[tex]q^{2}[/tex]" while the frequency of homozygous dominant genotype is represented by [tex]p^{2}[/tex]
[tex]q^{2} =[/tex] [tex]34[/tex]%
Since straight hair is a recessive trait. thus this phenotype is only expressed when the genotype of recessive allele is homozygous.
Therefore , frequency of the homozygous recessive genotype is equal to the frequency of straight hair in normal human population i.e [tex]34[/tex]%
hence, option B is correct

What information can be inferred if the estimated heritability of a trait is approximately 0.50?
Answer:
Variability in a trait is due to a combination of environmental and genetic factors, where at least 50% can be attributed to genetic differences.
Explanation:
The heritability of a trait is the influence of both, environment and genes, on the phenotype variation among individuals. The proportion between phenotypic variation and variation in genetic values is defined as heritability.
There are 2 types of heritability: Broad sense (genetic variation due to dominance and epistasis) and Narrow sense (genetic variation due to additive genetic values).
Heritability estimation is based on observations and empirical data analysis, which used mathematical models like Breeder's equation and statistical analysis. An 0,50 value indicates that variability in a trait is due to a combination of environmental and genetic factors, and genetic differences among individuals account for 50% of the variability in the trait, so it can be inferred that the trait is very complex, like a multifactorial condition, for which the environment can play an important role.
Which of these is the thinnest? A.plate B.lithosphere C.oceanic crust D.continental crust
Answer:
The correct answer is option C, that is, oceanic crust.
Explanation:
Of the mentioned options oceanic crust is the thinnest. The topmost layer of the oceanic part of a tectonic plate is known as the oceanic crust. In comparison, continental crust is less dense than oceanic crust. However, continental crust is thicker in comparison to the oceanic crust that exhibits an average thickness of about 7 to 10 kilometers. Approximately 40 percent of the surface of the Earth is occupied by continental crust.

Biologists use the fluid mosaic model to describe membrane structure. Which statements about the fluid mosaic structure of a membrane are correct? Select the three correct statements.
The diverse proteins found in and attached to membranes perform many important functions.
Because membranes are fluid, membrane proteins and phospholipids can drift about in the membrane.
The kinky tails of some proteins help keep the membrane fluid by preventing the component molecules from packing solidly together.
The framework of a membrane is a bilayer of phospholipids with their hydrophilic heads facing the aqueous environment inside and outside of the cell and their hydrophobic tails clustered in the center.
Membranes include a mosaic, or mix, of carbohydrates embedded in a phospholipid bilayer.
This is the best 3 answer about the fluid mosaic structure of a membraneFirst, The diverse proteins found in and attached to membranes perform many important functions. Second, The framework of a membrane is a bilayer of phospholipids with their hydrophilic heads facing the aqueous environment inside and outside of the cell and their hydrophobic tails clustered in the center. Third, Because membranes are fluid, membrane proteins and phospholipids can drift about in the membrane.
Explanation:
The fluid mosaic model illustrates the structure of the plasma membrane as a mosaic of elements including phospholipids, cholesterol, proteins, and carbohydrates that provides the membrane a fluid character. Plasma membranes range from 5 to 10 nm in thickness.
The fluid mosaic model is applied to represent the synergies of lipids and proteins in biological membranes. This model essentially proclaims the theory of lateral diffusion, stating that proteins can freely move about within a membrane and that such layers are assumed to effectively be two-dimensional.
With respect to the fluid mosaic structure of the membrane, the following three statements are true:
Many important processes are carried out by various proteins that are present in and bound to membranes.Membrane proteins and phospholipids can move across the membrane because the membrane is fluid.The bilayer of phospholipids that form a membrane consists of hydrophilic heads facing the aqueous environment inside and outside the cell, and hydrophobic tails clustered in the middle.Therefore, the correct options are A, B and D.
These descriptions of the essential features of the fluid mosaic model are accurate. This highlights how dynamic membranes are and the important roles proteins play in various biological processes. The fluidity of membranes allows proteins and lipids to move across the bilayer. With the hydrophilic ends interacting with water and the hydrophobic tails facing inward, the phospholipids are arranged to form a stable structure that acts as a barrier.
Therefore, the correct options are A, B and D.

Why do phospholipids form a bilayer in water?
Answer:
The hydrophobic tails aggregate to form a bi layer.
Explanation:
Phospholipids are major constituents of the plasma membrane. These are triglycerides having lipid part and phosphate part. The phosphate portion is the water-loving/hydrophilic and the glycerol tail or lipid part is water hating/hydrophobic. Hence, it is an amphipathic molecule. The hydrophobic tail aggregate with each other to form a lipid bilayer in the water. Therefore, the lipid tails prevent water molecules to enter the bilayer.

Select properties for the most abundant isotope of a particular element are given. which of these properties are the same for the second most abundant isotope of the element?
Mass number is the same for the second most abundant isotope of a particular element. Hence the correct option is a.
The mass number, representing the total number of protons and neutrons in an atomic nucleus, remains constant for all isotopes of a specific element. Therefore, for the second most abundant isotope of a particular element, the mass number remains the same as that of the most abundant isotope. This is because isotopes of an element share the same atomic number (number of protons) but differ in the number of neutrons, leading to variations in mass numbers.
While atomic number, neutron count, and electron configuration can differ between isotopes, the mass number remains a consistent property across isotopes of the same element. This stability in mass number reflects the cumulative mass of protons and neutrons, providing a crucial characteristic for identifying and distinguishing isotopes within the periodic table. Hence the correct option is a.

In which stage do the chromatids get separated and move toward opposite ends of the cell? A)P B)Q C)R D)S
Anaphase is the stage during which chromatids separate and move to opposite poles of the cell (option A).
Explanation:The stage in which chromatids get separated and move toward opposite ends of the cell is known as Anaphase. This stage is the third phase of mitosis. During anaphase, the sister chromatids are pulled apart by the shortening of the spindle fibers, which is a process analogously described as reeling in a fish by shortening the fishing line.
Each sister chromatid, now considered an individual chromosome, moves to one pole of the cell, ensuring that each pole has a complete set of chromosomes by the end of anaphase.
Hence, the answer is option A.

I’m the Illustration, which site is an example of a trench
The answer would be:
C
If you'd like to know why:
Ocean trenches are made when two oceanic plates CONVERGE. This is what we call convergent boundary, which is the process where two plates collide. When this happens, the less dense plate subducts or goes under the other plate. The point where the plate goes under is marked by a trench.
A trench is a deep, narrow section of the ocean floor, often formed by tectonic activity. An example is the Mariana Trench, the deepest part of the world's oceans. It would be depicted on an illustration as the deepest, narrow part of the ocean floor.
Explanation:In the context of geography, particularly geology and oceanography, a trench refers to a long, narrow, and extremely deep part of the ocean floor. These are typically formed by tectonic activity where one tectonic plate subducts or moves underneath another. An example of a trench would be the Mariana Trench in the Western Pacific Ocean. It is the deepest part of the world's oceans, with a maximum depth of more than 36,000 feet. When referring to the illustration, locate the deepest and narrow part representing the ocean floor; that would likely be the trench.

The notion that our brain organization and anatomy can change is called __________. A. recovery B. experience C. neurogenesis D. plasticity
The right answer is D. plasticity
Brain plasticity describes the ability of the brain to reshape its connections according to the environment and the experiences of the individual.
From the fetal life, connections between neurons are put in place. Later, after birth, some connections are preserved and others disappear.
The cerebral plasticity is at work during the apprenticeships which require the reworking of the nervous circuits. This is when some connections are reinforced between neurons (synapses). Indeed, the brain is not immutable. On the contrary, it evolves throughout life.
Cerebral plasticity is also possible thanks to undifferentiated cells that can replace accidentally destroyed neurons. For example, in the rat, if vibrisses (whiskers playing a sensory role) are removed, the organization of neurons in the brain is changed. The disappearance of a vibrissa leads to the reorganization of the somatosensory cortex.
