Answer: B. They had some system of religious beliefs about afterlife.
Explanation:
Neanderthals are believed to have had some system of religious beliefs because they buried their dead. They did not evolve into modern humans but rather interbred with them and had larger brains compared to Homo sapiens. Neanderthals lived during the ice age, not after, and were well-adapted to cold climates.
Explanation:The correct statement about Neanderthals is that they had some system of religious beliefs about the afterlife. Archaeological evidence, such as burial sites, suggest this could be true as they buried their dead, which may imply a belief in an afterlife. Neanderthals evolved from Homo erectus and did not evolve into Homo sapiens (modern humans), but they did interbreed with them.
Neanderthals had larger brains in absolute terms compared to modern humans, although their brain size is typically considered in proportion to their overall more robust body size. They lived during the ice age, thus they did not emerge after it. Neanderthals, indeed a distinct group from Homo sapiens sapiens, showed a great capacity to adapt to cold climates and had strong, muscular builds suited for survival in harsh conditions.

Study the diagram of a desert food chain .
What would most likely happen if the kangaroo rats were killed off and removed from the food chain ?
The removal of kangaroo rats from a desert food chain could lead to an overabundance of seeds and a decline in predator populations, such as kit foxes, potentially causing a collapse of the entire food web.
If the kangaroo rats were removed from a desert food chain, a ripple effect would take place, which would influence the entire ecosystem. As consumers of seeds, the absence of kangaroo rats could lead to an overabundance of seeds. Without kangaroo rats acting as a food source for their predators, such as kit foxes, these predators might face a decline in population due to a lack of food. This can create an imbalance, potentially leading to the overpopulation of some species while others might diminish or even become extinct. As tertiary consumers lose their prey, they may starve and die, which could even lead to the collapse of the entire food web. Ecosystems are interconnected, so the removal of one species, especially a key species like the kangaroo rat, can have far-reaching consequences.

It is the regulator of physiological tremor.
State one way a complete blockage at location X would affect the reproductive process ? Please answer !!
Answer:
There would be no fertilization.
Explanation:
When the fallopian tube is blocked, even after ovulation (an egg released by the ovary), it will be unable to travel down the fallopian tube towards the uterus. This way, even when the sperm swim up to the tube (where fertilization of the egg usually occur) after copulation, it will be unable to meet the egg and fertilize it. There will never be conception as long as there is blockage on location X.
How are sex-linked traits inherited? Alleles are passed from the parents’ sex chromosomes to nonsex chromosomes in the offspring. Alleles are passed from the parents’ nonsex chromosomes to the sex chromosomes in the offspring. Alleles are passed from the parents’ sex chromosomes to the sex chromosomes in the offspring. Alleles are passed from the parents’ nonsex chromosomes to nonsex chromosomes in the offspring.
Answer:
alleles are passed from the parents sex chromosomes
Explanation:
sex linked chromosemes are found in the y and x chromosomes in the reproductive cell i.e the sperm and ovum
The right answer for this question is C - sex-linked traits are inherited through alleles, which are passed from the parents' nonsex chromosomes to the sex chromosomes in the offspring. This means that the child will have a combination of both parents' nonsex chromosomes.
What are scattered over like pepper over the endoplasmic reticulum
Answer:
Ribosomes
Explanation:
The endoplasmic reticulum is a network of interconnected sacs and tubules distributed throughout the cytosol. There are two types of endoplasmic reticulum: smooth endoplasmic reticulum and rough endoplasmic reticulum. The rough endoplasmic reticulum is the one that has ribosomes studded on its outer surface. The presence of ribosomes gives the rough endoplasmic reticulum a rough appearance.
On the other hand, the smooth endoplasmic reticulum has a smooth outer surface due to the absence of ribosomes on it. The main function of rough endoplasmic reticulum is protein synthesis as ribosomes are the site for protein synthesis. The smooth endoplasmic reticulum is involved in lipid biosynthesis.
Which of the following is a heterotroph?
sunflower
potato
butterfly
soybeans
Answer:
Butterfly
Explanation:
a heterotroph is an organism that cannot make its own food, and therefore relies on other organisms for sustenance.
potatoes, sunflowers and soybeans are all plants and make their own food through photosynthesis
(they are called autotrophs)
However a butterfly relies on flowering plants to provide the nectar that it consumes.
if all the flowering plants suddenly died the butterflies would most likely die as well because their food source has been eliminated.
therefore the butterfly is a heterotroph

The diagram shows some of the steps in the flow of energy through an ecosystem. The arrows represent the transfer of energy. Label each arrow with the type of energy being transferred.
Answer:
Ecosystems maintain themselves by cycling energy and nutrients obtained from external sources. At the first trophic level, primary producers (plants, algae, and some bacteria) use solar energy to produce organic plant material through photosynthesis.
Explanation:
Unit 4: Ecosystems // Section 3: Energy Flow Through Ecosystems.
Your question is incomplete. please read below to find the full content.
In the diagram showing a typical food chain in an ecosystem, the arrow that connects the sun to plants represents the flow of radiant energy. The sunlight produces radiant energy, of which producers, such as plants, convert into chemical energy through photosynthesis.
The next arrow linking the plants to the rodent shows the flow of chemical energy in plants to primary consumers, such as rodents, who feed on them.
Also, rodents, when preyed upon by secondary consumers, such as wolfs and owls, pass on the same chemical energy to them. So the arrows connecting the rodent to the owl, and to the wolf both show the transfer of chemical energy from the rodent to the owl and wolf.
The next arrow shows the transfer of thermal energy from the wolf to the environment, as the wolf release heat from the body resulting from the daily functions it performs, and also, thermal energy is released to the surroundings as heat during the decomposition of the body of an animal.
The arrow linking the wolf to the decomposer which breaks down the body and waste of the wolf represents a transfer of chemical energy to the decomposer, as they break chemical bonds to obtain the energy they need to survive and grow.

O A. Silt loam
O B. Loam
C. Sandy clay loam
O D. Sandy loam
Your answer would just be straight Loam
Final answer:
A soil with 40% sand, 15% clay, and 45% silt is classified as silt loam, based on the soil textural triangle. The correct option is A.
Explanation:
Based on the soil texture diagram, a soil that is composed of 40 percent sand, 15 percent clay, and 45 percent silt is best classified as silt loam. This classification is determined using a soil textural triangle, where we trace horizontal, vertical, and diagonal lines based on the percentages of clay, silt, and sand. The point where these lines intersect corresponds to the appropriate soil class. Given the provided texture percentages, they intersect within the range specified for silt loam soils, which typically have more than 50% silt and no more than 25% clay.

Which of the following is a true statements about viruses?
Viruses have no nucleus.
Viruses are alive.
Viruses have a cell membrane.
All viruses are deadly.
The true statement about viruses is that they have no nucleus. Viruses are acellular entities that require a living host to reproduce and are not considered alive since they cannot maintain homeostasis or reproduce on their own.
The true statement about viruses is that viruses have no nucleus. Unlike living cells, viruses are acellular and do not have a cell membrane, cytoplasm, or ribosomes. They need a living host to reproduce as they cannot replicate outside of a host cell. Not all viruses are deadly, and while some can cause serious illness, many can be relatively harmless or cause only mild diseases.
The viral structure can be simplified as a nucleic acid (either DNA or RNA, but not both) encased in a protein coat known as a capsid, and in some cases, an envelope derived from the host's membrane with embedded glycoproteins that help the virus attach to the host cell. These characteristics make viruses unique entities on the borderline of living and non-living matter.

When does the cell pinch off and divide into two daughter cells in mitosis?
During cytokinesis, cell pinch off and divides into 2 daughter cells in mitosis.
What is cytokinesis?The division of the nucleus occurs after the cytoplasm (cytokinesis) during the cell cycle (karyokinetic).
Different cytokinesis processes take place during cell division in animal and plant cells.
Animal cells undergo cytokinesis by the production of two daughter cells as the parent cell's plasma membrane pinches inward along the equator, whereas plant cells undergo cytokinesis through the formation of a cell plate.

B. in plants the dna is not duplicated
C in plants a new cell wall forms to split the cell
D in animals there is no g0 phase or g2 phase
Answer: c in plants a new cell wall forms to split the cell
Yes the answer’s C.
so what’s your question?(tell me in comments)
C. In plants, a new cell wall forms to split the cell.
Mitosis is the process of cell division that occurs in both plants and animals, but there are key differences in how the process is completed.
In animals, during the final stages of mitosis (cytokinesis), the cell membrane pinches inwards, forming a cleavage furrow, which eventually splits the cell into two daughter cells. This process is possible because animal cells lack a rigid cell wall, allowing the membrane to easily bend and constrict.
In plants, however, the presence of a rigid cell wall makes it impossible for the cell to constrict in the same manner. Instead, during cytokinesis, plant cells form a cell plate in the center of the dividing cell. This cell plate grows outward, eventually developing into a new cell wall that separates the two daughter cells.
