When did lamarck publish his ideas on evolution answers?
Answer:
The correct answer will be 1809.
Explanation:
Jean-Baptiste Lamarck or Lamarck is best known for his theory of evolution called "Theory of Inheritance of Acquired Characteristics" which proposed a mechanism of change of species on the basis of use and disuse of organs.
Lamarck published series of books on paleontology and invertebrate zoology but his book Philosophie zoologique which was published in 1809 clearly stated his theories of evolution.
Thus, 1809 is the correct answer.

The assessment of the external and internal environments is called
Final answer:
The assessment of external and internal environments is crucial for environmental science and business management, known as ambulatory assessment in human-centric studies and as part of environmental impact assessments in environmental policy. These assessments look at factors affecting natural settings and organizations, including physical environments, health services, and various societal pressures.
Explanation:
The assessment of the external and internal environments is an important aspect of environmental science and business management. This evaluation is crucial in understanding the influences that affect an organization or the natural settings in which humans inhabit. When referring specifically to the study of human-centric environments, this can be encompassed by the term ambulatory assessment, which includes methodologies that assess behavior, physiology, experience, and environments in naturalistic settings. In a business context, this is often aligned with strategic management and environmental analysis.
A large population of mice is isolated on an island. there are two varieties of the mice, brown and gray. their fur colors closely match the gray rock outcrops and brown soils of the island. hawks are their main predators. this situation most likely reflects the outcome of __________.
The isolated mice population with brown and gray fur demonstrates an example of diversifying natural selection, where both fur colors provide camouflage advantages in different areas of the island, leading to increased genetic variance over time.
The situation described with the mice on the island is an example of natural selection. The mice have fur colors that match the environment—brown soils and gray rock outcrops—which provide camouflage against their main predators, hawks.
This is an outcome of diversifying selection, a form of natural selection where two or more distinct phenotypes can each have their advantages and are selected for, while the intermediate phenotypes are, on average, less fit. The brown and gray mice thrive because they blend into their respective environments well, reducing the likelihood of predation in contrast to any hypothetical intermediate colorations that may stand out and lead to higher predation rates.
Over time, genetic variance increases in the mouse population as the two color varieties continue to survive and reproduce more successfully.

If a cell did not have ribosomes, it would be unable to
Without ribosomes, a cell would be unable to perform protein synthesis, which is vital to many cell functions. Ribosomes translate the code in mRNA into a sequence of amino acids to form proteins. These proteins are essential components, such as enzymes, hormones, or structural elements of a cell.
Explanation:If a cell did not have ribosomes, it would be unable to perform protein synthesis. Ribosomes are complex macromolecules that translate the code provided by the sequence of nitrogenous bases in mRNA into a specific order of amino acids in a protein. Hence, amino acids are the building blocks of proteins, and without ribosomes, a cell would become incapable of producing proteins essential to its functions such as enzymes, hormones, antibodies, pigments, structural components, and surface receptors.
Moreover, ribosomes, present in large numbers in cells that synthesize large amounts of protein, might be seen either as clusters or single tiny dots floating freely in the cytoplasm when viewed through an electron microscope. They may also be attached to the cytoplasmic side of the plasma membrane or the endoplasmic reticulum.
Overall, ribosomes are indispensable for a cell's function and survival since they play a fundamental role in protein synthesis which is essential to virtually all cell activities.

A student is looking at a picture of a cell taken through a microscope. the presence of which of the following would indicate that the cell is Eukaryotic
A.Cytoplasm
B.DNA
C.Nucleus
D.Plasma Membrane
The presence of a nucleus would indicate that the cell is eukaryotic. Therefore, option (C) is correct.
What are eukaryotic cells?Eukaryotic cells are characterized by the presence of a nucleus, which is a membrane-bound structure that contains the cell's DNA. The nucleus is surrounded by the cytoplasm, which is the gel-like substance that fills the cell and contains the cell's organelles. The plasma membrane is the thin, flexible barrier that surrounds the cell and separates the cell's interior from the external environment.
In contrast, prokaryotic cells do not have a nucleus or other membrane-bound organelles. They are smaller and simpler in structure than eukaryotic cells and have a relatively small amount of genetic material.
So, in this case, the presence of a nucleus in the cell would indicate that it is eukaryotic, while the presence of cytoplasm, DNA, and a plasma membrane would not necessarily be indicative of whether the cell is eukaryotic or prokaryotic.

Police officers have found human skeletal remains including a pelvis, and they ask your help in determining the individual's gender. which feature will you examine to help you make this determination?
The feature that you need to use in examining and make a determination whether the skeletal remains in the pelvis is either male or female is by analyzing its size and construction. It is because males have larger pelvis bone and are robust elements compared to females who have smaller and are light in terms of construction.
Answer: the size
Explanation: Even the fact that there are at least seven diagnostic criteria to differenciate female and male pelvis, one of the most important is the size of the bone. A female pelvis is larger and broader than a male pelvis. The male pelvis is taller, narrower and it is also more compact than the female pelvis. This is why, if I had to help in a police investigation, I would check the size of the bone.

Scientists used data from gregor mendel’s studies to conclude that information about traits is passed from parents to offspring through _____.
Answer:
The question lacks options, the options are:
a. behavior
b. species
c. genes
d. proteins
The answer is C, genes
Explanation:
Gregor Mendel discovered in his various experiments, that parents pass information to their offsprings via what he called UNIT FACTOR. This unit factor was later known to be GENES. Mendel discovered that genes of an organism usually comes in two forms (one from each parent). These forms are called ALLELES. Each allele is responsible for a different trait for that same gene.
In his law of segregation, Mendel stated that each allele of a gene separates into gametes. This is the means by which information in the gene is passed across to offsprings. Scientists, later discovered the gene to be a segment of the DNA that encodes information to produce certain proteins responsible for obvious traits called phenotype. The information needed by an individual is encoded in these genes, which is passed across to offsprings during reproduction (meiosis).
What are some structures inside a cell that will help it live and perform its role in an organism?
Cells contain organelles such as mitochondria and chloroplasts that perform essential tasks, enabling the cell to live and function within an organism. The differences between prokaryotes, eukaryotes, nerve cells, and muscle cells all serve different functions within an organism.
Explanation:Cells, the fundamental units of life, contain small structures known as organelles that perform various tasks to help the cell live and perform its roles within an organism. These organelles include mitochondria that produce energy and in the case of green plants, chloroplasts that enable the conversion of sunlight into sugars through photosynthesis.
Prokaryotes and eukaryotes are classified as such based on whether or not their cells contain membrane-bound organelles and a nucleus. Prokaryotic organisms, like bacteria, are single-celled or colonize without these features, while cells in eukaryotic organisms, such as humans, possess membrane-bound organelles and a nucleus.
The structure of different organelles within a cell allows it to carry out different functions. For example, the structure of nerve cells, with their long projections, helps them transmit electrical signals and muscle cells are equipped with a high number of mitochondria to enable movement.

What is the name for the diffusion of water across a semipermeable membrane
Osmosis is the diffusion of water across a semipermeable membrane, which helps maintain water balance in cells.
Explanation:The diffusion of water across a semipermeable membrane is known as osmosis. It's a fundamental concept in biology, particularly in cell biology. Osmosis helps maintain water balance in cells. For instance, if a cell is placed in a solution that is hypertonic (higher solute concentration than the cell), water will move out of the cell due to osmosis, and the cell can shrink. Conversely, if a cell is placed in a hypotonic solution (lower solute concentration), water will move into the cell, and the cell can swell and possibly burst.
