The displacement of the object is 303.75m.
What is displacement?Distance covered by a body in a particular direction is called displacement. To calculate displacement from a velocity-time graph, we calculate the area under the curve.
The displacement is covered by drawing perpendiculars on the time axis. Let AB be the first and CD be the second perpendicular.
Extend A to CD at E.
Now, area of ABCD trapezium
= (AB + DC)/ 2 × AD
= (10.5 + 30)/2 m/s × 15 s
= 303.75 m is the area under the curve.
Therefore, 303.75 m is the displacement of the object.

Determine if the statement is true or false, and why. “Most features are caused by a mixture of inheritance and environmental factors.”
A. False, it should read “Most features are caused by inheritance.”
B. True
C. False, it should read “Most features are caused by environmental factors.”
D. False, it should read “All features are caused by a mixture of inheritance and environmental factors.”
The statement is False, it should read, Most features are caused by inheritance of a character. Thus option A is correct.
What is inherited trait ?Inheritance is defined as the transfer of genetic information from parents to their offspring.
The transferred characters or traits include eye color, hair color, and blood type.
Trait can be defined as the genetic character which can be transmitted by the parent to its offspring during fertilization.
The trait which is expressed phenotypically is called as dominant trait while the other trait which is not expressed called as recessive trait.
These variations are observed in the species due to survival benefits or genetic drift.
Acquired traits are acquired by an individual in his lifetime which is due to their own activities or external influence.
Like inherited traits, acquired traits are unable tp pass to the next generation like ability to dance, cook.
Thus option A is correct.

Give a positive and a negative impact of an environmental law or regulation.
Answer:
negative impact
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water. These negative impacts can affect human behavior and can prompt mass migrations or battles over clean water.
positive impact
Environmental regulations have greatly improved air and water quality, especially in areas that were dirtiest before regulation. Reducing airborne particulates is especially beneficial, saving thousands of lives and preventing millions of illnesses each year.

what are the two characteristics of Pine due to which it is not placed under sub division angiosperms
Answer:
The angiosperms, or flowering plants, are the largest and most species-rich phylum of plants, with more than 250,000 species estimated.
Defining Characteristics
The term "angiosperm" derives from two Greek words: angeion, meaning "vessel," and sperma, meaning "seed." The angiosperms are those plants whose seeds develop within a surrounding layer of plant tissue, called the carpel, with seeds attached around the margins. This arrangement is easily seen by slicing into a tomato, for example. Collectively, carpels together with the style and stigma are termed the ovary, and these plus associated structures develop into the mature

What is phenotype?The set of qualities or characteristics that can be observed in an organism are known as its phenotype in genetics.
The word includes an organism's anatomy, developmental processes, physiological and biochemical characteristics, behaviour, and the outcomes of behaviour.
The genotype of an individual is their own DNA pattern. More specifically, the two alleles a person acquired for a particular gene are referred to by this phrase.
The clinical presentation of a patient is the observable expression of this genotype, or phenotype.
A, B, AB, and O are the four phenotypes of blood that can occur. The gene that determines blood type has three alleles. Six distinct genotypes are possible because there are three different alleles.
Thus, the correct option is B.

First, there is a need to understand what the carrying capacity is as it relates to the environment:
Carrying capacity refers to the maximum number of individuals of a particular species that and environment can support based on the resources it has. The population of a species in an environment grows and oscillates around the carrying capacity of the environment.Now let us look at the graph. The population size grew from 0 and then leveled off at 2,000 with time. The leveling-off also happened without any oscillation, meaning that the maximum population size the environment can support is 2,000.
Hence, the portion on the graph that indicates the carrying capacity would be the plot where the population size is 2,000 and the time being between 12 and 18. This has been circled and labeled as 'K' in the attached image.

1. Sediments in the outwash are larger.
2. Sediments in the outwash are sorted
3. Sediments in the outwash are more angular
4. Sediments in the outwash are older.
Answer:
2. Sediments in the outwash are sorted
The difference between sediments deposited in outwash and sediments deposited in moraines is that-Sediments in the outwash are sorted. Therefore, the correct option is 2.
What is the sediment of outwash and moraines?Outwash is the sediment that is carried away from a glacier by meltwater and deposited in streams and rivers. This sediment is typically well-sorted, which means that particles are relatively uniform in size, shape, and composition.
Moraines are piles of unsorted sediment that are left behind by a glacier as it retreats. This sediment is typically a mix of different particle sizes, shapes, and compositions.
The glacier's movement is not strong enough to sort the sediment of moraines, so it remains unsorted. Therefore, the correct option is 2.

DNA
Carbohydrates
Proteins
Lipids
Answer:
Carbohydrates
Explanation:
Fatty acids are building blocks of lipids
Nucleotides are building blocks of DNA
Amino acids are building blocks of protiens
Monosaccharides are building blocks of carbs
Monosaccharides are the building blocks to carbohydrates. The correct option is B.
The constituent parts of monosaccharides are what make up carbs. Carbon, hydrogen, and oxygen make up the macromolecules known as carbohydrates in the ratio of 1:2:1.
Simple sugars like glucose and fructose are monosaccharides, which can combine through dehydration synthesis to create bigger carbohydrate molecules.
In addition to serving as an essential source of energy for living things, carbohydrates also function as structural support for things like plant cell walls and as energy storage in the form of starch and glycogen, respectively.
To create complex carbohydrates like disaccharides (like sucrose) and polysaccharides (like starch and cellulose), the monosaccharides combine through glycosidic linkages.
Thus, the correct option is B.

The principle of dominance is a ______ inheritance pattern.
It’s states traits that are ______ mask the traits that are______
The answers to the missing gaps are: MENDELIAN, DOMINANT, RECESSIVE
Explanation:
Gregor Mendel proposed the principles that govern inheritance. These principles are called MENDELIAN inheritance pattern because they align with or follow the principles of Mendel. One of these principles by Mendel is the LAW OF DOMINANCE.
Mendel has previously stated that there are two alleles for each gene. Each contrasting allele encodes a different phenotype. However, the law of dominance states that one of these two alleles called DOMINANT allele has the ability to mask the phenotypic expression of the other allele called RECESSIVE allele. In other words, a dominant trait will mask the recessive trait.
For example, in a gene Tt, allele 'T' for tallness is dominant and hence, will mask the phenotypic expression of allele 't' for shortness. This means that the tall trait (dominant) will mask the short trait (recessive) as explained by Mendel's law of dominance.
Describe the process of germination and plant growth you observed in the lab activity for a monocot plant.
Answer:
Germination is the process by which a plant develops from a seed. The most common example of germination is a sprout of a seedling emerging from the seed of an angiosperm or gymnosperm. However, the development of a daughter spore from a spore, such as the growth of a mycelium from a fungal spore, is also germination. Therefore, germination can be understood in the general sense as anything that becomes larger from a small entity or a living organism, is a commonly used method in many seed development projects. alike.
