Certain kinds of shells are always found in rock layers lower than layers with plant fossils. Dinosaur fossils show up only in layers above or with plant fossils what does this tell you about When these organisms lived
Answer:
This shows that once animals were on the surface there were plants for them to eat.
Dinosaur fossils show up only in layers above or with plant fossils. This shows that dinosaurs were animals that lived with plants and feed on plants.
What are fossils?Fossils are the remains of plants, animals, and other substances that are preserved under the layers of rocks and earth. They are the preserved form that gives the knowledge of organism present in before times.
Dinosaurs lived 65 million years ago, but still, their bones and remains are found on earth. They were found with the fossils of plants, so this tells us that plants were also present at the time of their presence, and they fed on plants.
Thus, only strata above or in conjunction with plant fossils do dinosaur fossils appear. This demonstrates that dinosaurs were also plant-eating and lived with plants.

Which factors involving the activities of people are a threat to biodiversity? pollution and succession habitat loss and predation poaching and habitat loss succession and poaching
Both poaching and habitat loss are a threat to biodiversity
Habitat loss refers to the destruction of natural ecosystems and consequent reduction in the amount of habitat available for the species living in a given area. Habitat loss is the greatest threat to ecosystems biodiversity and conservation worldwide by deteriorating natural areas and thereby reducing species distribution ranges. Habitat loss is primarily due to the expansion of human populations and human activities (i.e., mining, logging, trawling, industrial production, urbanization, etc.).
Poaching refers to the illegal killing of wild animals for different reasons (e.g., meat, recreation, etc.), in violation of international, federal, state/provincial, or local laws. Poaching can drastically reduce the number of organisms in natural populations, thereby this human activity can reduce genetic diversity and eventually may lead to the extinction of natural populations/species.
In conclusion, both habitat loss and poaching can reduce the number of organisms, reduce biodiversity and eventually cause the extinction of natural populations.

what are the basic building blocks of fats?
Answer:
Fatty acids are the building blocks of the fat in our bodies and in the food we eat. During digestion, the body breaks down fats into fatty acids, which can then be absorbed into the blood. Fatty acid molecules are usually joined together in groups of three, forming a molecule called a triglyceride.
2. How does the development of a nervous system and sense organs relate to increasing complexity of multicellular animals?
The development of nervous system and sense organs in multicellular organisms has led to evolution of species in a more complex manner.
Complexity of multicellular organisms• The development of nervous system and sense organs has permitted for a greater level of perception and better equipped organisms.
• It has permitted the organisms to collect resources, react to their surroundings, and take advantage of their surroundings.
• This has resulted in the organisms to survive longer and accommodate into bigger types of body.
• Such amendments has thus permitted organisms to become more complex and move up the food chain.
Thus, the development of nervous system and sense organs is associated with increasing complexity of multicellular animals.

Which of the following types of cells suppress immune responses?a. Neutrophilsb. Plasma Cellsc. Macrophagesd. Regulatory T Cells
Answer:
The correct answer is d.
Explanation:
Regulatory T-cells are a class of T cells which are part of the immune system that suppresses immune response. They are called regulatory because they assist in "checking" the excesses/overreaction during immune response.
NOTE:
Neutrophils are phagocytic in nature; they ingest and destroy microorganisms or other foreign molecules.
Plasma cells synthesize antibodies which are produced in response to antigens. They are target foreign particles for digestion by other immune cells.
Macrophages are also phagocytic in nature usually found at sites of an infection.

Explanation:
Bone does not amplify sound during speaking is _____________________
Answer:
Bone is a solid tissue, which resists a high impact of forces in its major axis.
The function of this fabric is not to transmit sounds, since it does not provide the elasticity, and the necessary elongation that is needed to generate the rope effect as in the case of muzzle cords.
Explanation:
The more rigid and less elastic the fabric is, the less sound it will transmit.
Sound strings, or mouth strings, are those that tighten, are flexible and resonate with different vibrations, in the case of bone tissue, sound vibrations are not influenced in their conformation because they do not have the ability to transmit them. .
The bone tissue, transmits impact forces or high newton levels, does not fulfill the function of transmitting vibrations and emitting sounds in terms of this type of vibrations and their frequencies.
A focus of environmental science not studied in ecology is the
Answer:
The influence of human activities on the environment
Explanation:
Anthropogenic activities may have negative effects on the environment by declining its biodiversity and by reducing natural resources. Human activities affect the environment through the use of fossil fuels (greenhouse gases), by contributing to the pollution of extensive areas, by overpopulation, eutrophication, deforestation, etc. The most significant effects of anthropogenic activities include the loss of biodiversity, climate change (global warming), habitat fragmentation, environmental degradation (e.g., ocean acidification), the introduction of invasive species, species extinction, etc.

the all-or-none response of a neuron is similar to:
Answer:
The all-or-none law is a principle that states that the strength of a response of a nerve cell or muscle fiber is not dependent upon the strength of the stimulus. If a stimulus is above a certain threshold, a nerve or muscle fiber will fire.
The all-or-none response of a neuron is similar to a gun that either fires or doesn't. The correct option is B.
What is an all-or-none response?According to the all-or-none principle, signal transmission between neurons is solely dependent on the initial threshold being met rather than the stimulus's intensity.
In other words, neurons either fully or totally avoid transmitting an impulse via the synapse to the subsequent neuron.
According to the all-or-none law, the strength of a nerve cell's or a muscle fiber's response is not influenced by the stimulus's intensity.
A nerve or muscle fiber will activate if a stimulus is present above a predetermined threshold.
Therefore, the correct option is B. a gun that either fires or doesn't.

To be characterized as a chordate, an organism must:________.
A) possess a backbone in both the larval and adult stages
B) display all four key characteristics of Chordata in both the larval and adult stages
C) display each of the four key characteristics of the chordates at some point in the life cycle
D) possess a backbone in at least one life stage.
Answer:
C) display each of the four key characteristics of the chordates at some point in the life cycle
Explanation:
To be characterized as a chordate, an organism must display each of the four key characteristics of the chordates at some point in the life cycle. Therefore, the correct option is C.
To be characterized as a chordate, an organism must display four key characteristics at some point in its life cycle.
These characteristics include having a notochord (a flexible rod-like structure), a dorsal hollow nerve cord, pharyngeal slits or pouches, and a tail.
It is not necessary for all four characteristics to be present simultaneously or in both the larval and adult stages. As long as the organism exhibits these characteristics at some stage of its life, it can be classified as a chordate.
