Which principle states that rock fragments in sedimentary layers must be older than the surrounding sediments?
A) Principle of inclusions
B) Principle of unconformity
C) Principle of cross-cutting relationships
D) Principle of superposition
A) Principle of inclusions
Explanation:
The principle of inclusions states that any rock fragments in a sedimentary layer must be older than the layer. For example, the cobbles in a conglomerate must have been formed before the conglomerate.
Answer:
D) Principle of superposition
Explanation:
The principle of superposition, since there is no inversion of strata, tells us that the lower rock layers are older than the upper ones.
What is the general relationship between a galaxy's distance from earth and its speed?
THIS IS A WRITTEN RESPONSE!!!
Answer:
Hubble's law, also known as the Hubble–Lemaître law, is the observation in physical cosmology that galaxies are moving away from Earth at speeds proportional to their distance. In other words, the farther they are the faster they are moving away from Earth.

Select the most accurate description of how antibodies are produced. Select one: a. cytotoxic T cells stimulated by helper T cells b. B cells that differentiate to form plasma cells c. helper T cells stimulated by various cytokines d. in the red bone marrow e. natural killer cells as they lyse cancer cells
it is the red bone marrow that produced anti bodies
The most accurate description of how antibodies are produced is B cells that differentiate to form plasma cells
Option (b ) is correct.
The most accurate description of how antibodies are produced is through B cells that differentiate to form plasma cells. B cells are a type of white blood cell that plays a crucial role in the adaptive immune response. When a B cell encounters an antigen (a foreign substance, such as a virus or bacteria), it recognizes and binds to it. This binding activates the B cell, leading to its differentiation into plasma cells.
Plasma cells are specialized B cells that secrete large amounts of antibodies, also known as immunoglobulins. These antibodies are specific to the antigen that triggered their production. Antibodies help neutralize or eliminate the antigen by binding to it and marking it for destruction by other components of the immune system.
Option a is incorrect because cytotoxic T cells are involved in directly attacking and killing infected cells, not producing antibodies.
Option c is incorrect because helper T cells play a role in activating B cells and other immune cells, but they do not directly produce antibodies.
Option d is incorrect because the red bone marrow is the site where various blood cells, including B cells, are produced, but it is not directly involved in antibody production.
Option e is incorrect because natural killer cells are a type of immune cell that is responsible for detecting and destroying infected or cancerous cells through a process called lysis. They are not involved in antibody production.

which condition would disturb the hardy-weinberg equilibrium and cause the gene pool to change?
Answer:
The Hardy-Weinberg equilibrium can be disrupted by deviations from any of its five main underlying conditions. Therefore mutation, gene flow, small population, nonrandom mating, and natural selection will disrupt the equilibrium
Explanation:
If the conditions to maintain the Hardy-Weinberg equilibrium are: no mutation, no gene flow, large population size, random mating, and no natural selection. The Hardy-Weinberg equilibrium can be disrupted by deviations from any of its five main underlying conditions, means the reverse things would disturb the hardy-weinberg equilibrium.

When a nucleus divides by mitosis, all of the information from the nuclear
chromosomes is passed on to the daughter cells.
Mitosis is a cell division process that results in the formation of two daughter cells during growth processes and in the replacement of worn-out tissues in the body.
The cells produced must have all the information as the cells replicated
have specialized functions which must be passed from parent cells to the daughter cells.

Light energy that is captured in photosynthesis is converted to ______ energy stored in the chemical bonds of molecules.
Answer:
Light energy that is captured in photosynthesis is converted to chemical energy stored in the chemical bonds of molecules.
Light energy that is captured in photosynthesis is converted to chemical energy stored in the chemical bonds of molecules.
What is photosynthesis?Photosynthesis is essential to most life on Earth. Plants, algae, and some types of bacteria carry out the process by capturing solar energy to create oxygen (O2) and chemical energy stored in glucose (a sugar). Consequently, herbivores get this energy from consuming plants, and carnivores get it from eating herbivores.
Chloroplasts, which are tiny organelles found inside plant cells, are there to store solar energy. Chlorophyll, a light-absorbing pigment found in the thylakoid membranes of the chloroplast, is what gives plants their green hue. Chlorophyll absorbs energy from blue and red light waves during photosynthesis while reflecting green light waves, giving the appearance of a green plant.
