Flowering plants are ___.
A.) gymnosperms
B.) laurasians
C.) angiosperms
D.) archaeopteryx
Answer:
C
Explanation:
The flowering plants, also known as Angiospermae, or Magnoliophyta, are the most diverse group of land plants, with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. Etymologically, angiosperm means a plant that produces seeds within an enclosure; in other words, a fruiting plant. The term comes from the Greek words angeion and sperma.

What characteristic do bacteria, fungi, and plants share that other kingdoms do not?
List the inputs and outputs of photosynthesis. what parts of the plant are responsible for taking in each of the inputs
Answer:
Inputs: 6CO2 and 6H2O with light energy
output: C6H12O6 and 6O2
Leaves, roots are the major parts of the plant responsible for taking in each of the inputs
Explanation:
The photosynthesis process is the process where carbon dioxide and water are converted into glucose and oxygen in the presence of light. The products of this process act as substrates during cellular respiration. The photosynthesis process can be represented as:
6CO2 + 6H2O ------> C6H12O6 + 6O2
inputs ↑ outputs ↑
Inputs of the reaction are:
1. Carbon dioxide - 6CO2
2. Water - 6H2O
3. light energy from sun
Outputs are:
1. Glucose - C6H1206
2. Oxygen - 6O2
b. The parts of the plant is responsible for taking inputs during photosynthesis is the leaf as it has chloroplast that trapped the light and also helps in getting carbon dioxdie and roots that helps in absorbing water.
How does the process of hydration cause chemical weathering?
A.
Water reacts with iron minerals in rock to form rust.
B.
Moving water transports sediment from rock.
C.
Increased density adds pressure to the molecules in rock.
D.
Acidic water dissolves calcite in carbonate rocks.
Answer:
A. Water reacts with iron minerals in rock to form rust.
Explanation:
Generally, weathering is the process by which rocks are broken down or disintegrated into smaller particles. However, as the name implies, chemical weathering is the weathering facilitated by chemical reactions.
However, there are various types of chemical weathering, of which one is HYDRATION. Hydration is a type of chemical weathering which involves the reaction of water with the chemical constituents of rocks, which eventually disrupt or changes the structure. Therefore, in chemical weathering, water reacts with iron minerals in rock to form rust.

Michaelis and Menten studied the enzyme sucrase, which uses sucrose as a substrate. Assume that lactose is a competitive inhibitor of sucrase. This could be demonstrated by appropriate kinetic experiments. Think about the kind of data that would be collected in these experiments.On the axes below, show appropriate double-reciprocal plots that would demonstrate that lactose is a competitive inhibitor. Label the axes, and any intercepts with X and Y axes appropriately.The graph can be used to determine whether or Vmax has changed in the presence of lactose. State what it about the graph that allows this, and whether Vmax has changed in the presence of lactose.
Solution :
In the context, Menten and Michaelis were doing a research. They are studying about the enzyme sucrase that can use sucrose like a substrate.
The intercept on the y-axis gives the value of the Vmax.
As the intercept is same for both the plots, Vmax does not change upon the competitive inhibitor of sucrase.
The graph plotted is provided below.
When a red 4 o'clock flower with a white flower, all of the offspring are pink. This type of inheritance is known as:_______ a. codominance b. incomplete dominance c. multiple alleles d. epistatsis
Answer:
b. incomplete dominance
Explanation:
Incomplete dominance is a type of inheritance that does not confirm to Mendel's principles of inheritance i.e it is non-mendelian. Incomplete dominance occurs when an allele of a gene does not completely mask the expression of another allele of the same gene, hence, the two alleles combine to form a heterozygous that is different but intermediate of both parent phenotypes.
This is the case in this question where the red allele (R) of a four o'clock plant is INCOMPLETELY DOMINANT over the white allele (W), hence, they both produce an intermediate pink phenotype (RW), which is a blending of both red and white phenotypes.
When a person is cut, the injured tissue initially releases chemical signals into the bloodstream. These chemicals signal platelets to be attracted to the injured area. if this is a positive feedback mechanismwhich of the following must be part of the process? The heart would slow down to cause a drop in blood pressure. Platelets would release signals to stimulate the production of more platelets. Blood vessels around the cut would constrict to decrease the surface area exposed to the platelets. Chemical signals released would cause a decline in platelet production
Answer:
Platelets would release signals to stimulate the production of more platelets
Explanation:
Positive feedback mechanism is one of the two types of feedback mechanisms (other being negative feedback mechanism) in which the products of a process stimulates more of that product to be synthesized or produced. In other words, the result of a reaction increases the secretion of more results.
In this case where the injured tissue of a cut initially releases chemical signals into the bloodstream. These chemicals signal platelets to be attracted to the injured area. However, if this is a positive feedback mechanism as explained above, Platelets would release signals to stimulate the production of more platelets.

Which is an example of an environmental influence that would most likely result in natural selection?
O The soil in a field always has lots of nutrients, so corn plants in a population can grow quickly. O A fish is bom with a genetic mutation that produces a longer tail, allowing the fish to swim faster than others in the population
O A food resource disappears in a pond, and some frogs in a population can eat the remaining food resource, while others cannot O The temperature in a lake remains constant, so most of the turtle population survives to adulthood
Answer:
The best example of environmental influence that would most likely result in natural selection is that a food resource disappears in a pond, and some frogs in a population can eat the remaining food resource, while others cannot.
Explanation:
Among the environmental factors that can influence natural selection at a given time is the availability of food. Natural selection, from the point of view of evolution, is influenced by adverse environmental conditions, being food shortage one of them.
In conditions of food shortage in a pond, as in the example of the frog population, only the most apt will be able to take advantage of nutritional resources, while the less apt will not be able to survive. The ability to survive with little food available becomes an inherited trait that will be passed on to future generations.
In any case, tolerance to adverse conditions becomes adaptation, which translates into survival and reproductive success.
The other options are not correct because none of them show environmental pressure that can lead to natural selection.Answer:
food resource disappears in a pond, and some frogs in a population can eat the remaining food resource, while others cannot.

A teacher modeled part of a DNA molecule using two of these coiled springs. Which part of the DNA was the teacher most likely modeling?
Answer: The part of DNA that the teacher was modelling would be the backbone of DNA.
Explanation:
The DNA is made of double helical structure which is twisted. In the structure of DNA two strands are coiled among each other.
The DNA consists of the nitrogenous bases, phosphate groups and deoxy-ribose sugar.
The backbone of DNA is made up of sugar( alternating )and phosphate group.The nitrogenous bases such as adenine, cytosine ,guanine and thymine are joined to the deoxy-ribose sugar.
This backbone part was part that the teacher was making as a model by using two coiled springs.
Are cells and DNA the same thing?
Answer:
We learned in biology class that every cell in the body has the same DNA. Whether a heart cell, skin cell or muscle cell—they all read from the same genetic blueprint. Now, scientists are learning there is more to the story.
Almost all of the cells in your body share the same DNA as was found in that first cell. Your DNA contains all of the information needed for making you. This information is stored in the over 20,000 human genes found in almost all your cells.
Your teacher has given you a plant to observe. You notice the leaves of the plant are dotted with openings. These openings are known as stomata. When open, stomata allow the plant to take in carbon dioxide, release oxygen. Moisture also evaporates through stomata helping to draw water from the roots up into the plant. How does the presence of stomata allow cell organelles to work together?
