uncovering a cluster of Brachiopods You have a second group working about 300 feet above the bottom of the canyon, uncovering impressions from a variety of plants
such as fems and horsetails. While you are waiting for the exact age of the rock layers to be determined, what can you tell about the age of the fossils based on
where they are
A. You cannot determine anything yet.
B. They are all about the same age.
C. The plants must be older than the Brachiopods.
D. The Brachiopods must be older than the plante

Answers

Answer 1

Answer:

C

Explanation:

because the plants are farther down lol

Answer 2

Paleontology establishes the geological age of the organisms. Based on the height of the fossils discovered at the Grand Canyon, it can be concluded that plants were older than the Brachiopods. Thus, option C is correct.

What are fossils?

The dead remains and decaying materials of the plants and animals stored and preserved under the sediments and rock layers over a period of many years are said to be called fossils.

The fossils are evidence of the evolution as well are used to determine the geological age of the species based on their occurrence of them in the rock layers.

The fossils of plants like horsetails and ferns were found 300 ft above the Canyon while Brachiopods at 10 feet above Canyons that tell that plants were found earlier than the former species.

Therefore, option C. the plants existed prior to the Brachiopods.

All of the following are evidence for the big bang except: A. Cosmic background radiation B. Almost all galaxies are red-shifted C. The sound from the bang echoes though the universe D. The universe is expanding

Answers

Answer: C. The sound from the bang echoes though the universe

Explanation:

Cosmic background radiation proves the big bang because it shows that as a result of the big bang, the early universe was really hot but cooled as it expanded. Cosmic background radiation is the result of that earlier heat.

Galaxies being red-shifted means that the space between galaxies is increasing which means that the universe is expanding which provides evidence for a big bang because particles move away the single point they are concentrated in.

There was no actual bang from the big bang and sound cannot echo through space so c is incorrect.

A sperm fertilized an egg. Which two structures will the fertilized egg contact?
ovary and fallopian tubes
fallopian tubes and uterus
uterus and cervix
cervix and ovary

Answers

Answer:

B Edge 2021

Explanation:

I just took the test

When a sperm fertilizes an egg, the fertilized egg, also known as a zygote, will travel from the fallopian tube to the uterus, where it will implant and grow into a fetus. Therefore, the correct option is B.

What is a fertilized egg?

A fertilized egg is also known as a zygote. It is a single cell that results from the union of a sperm and an egg during fertilization. Fertilization typically occurs in the fallopian tube of a female reproductive system when a sperm successfully penetrates and merges with the egg.

The egg is released from the ovary and travels through the fallopian tubes towards the uterus. It is in the fallopian tubes where the egg can be fertilized by a sperm, forming a zygote.

The zygote will then continue to travel through the fallopian tube towards the uterus. As it approaches the uterus, the zygote will undergo several cell divisions, forming a ball of cells known as a blastocyst.

The blastocyst will then implant into the lining of the uterus, where it will continue to grow and develop into a fetus. The cervix, which is the lower part of the uterus, plays a role in pregnancy by keeping the fetus inside the uterus during gestation and then opening to allow for delivery during childbirth.

Therefore, option B) the fallopian tubes and uterus is correct.

B: Humans, chimpanzees, and other primates share a common ancestor.

Explanation:

According to the theory of evolution, organisms of a particular species change in their characteristics over several generations because of the process of natural selection. The idea of evolution derives from the fact that all species are related and gradually change over time.

Species which are somewhat related all share a common ancestor. Hence, humans, chimpanzees, and other primates all share a common ancestor.

To control the population of insects, if insecticides are used then how it will affect the population of birds?

Answers

Answer: Birds are exposed to insecticides through ingestion by mistaking, they ingest pesticide residues when they trim their feathers with their beaks or may drink or bathe in contaminated water. The effects can range from death due to poisoning to a variety of effects such as weakening of eggshells, deformation and slow growth of chicks, lack of appetite, weight loss, immune system damage, hormonal disruption. In addition, insect-eating birds are at a loss when insecticides cause a drop in the number of insects available, especially when they have chicks to feed.

Explanation:

Insects are a class of invertebrate animals characterized by having one pair of antennae, three pairs of legs and two pairs of wings (which, however, may be reduced or missing). They comprise the most diverse group of animals on Earth with an estimated thirty million undescribed species, potentially representing more than 90% of the life forms on the planet. Moreover, they can be found in almost every environment on the planet, so they are not only highly diverse, but also incredibly abundant.

Like any species on the planet, insects play a vital role in the ecosystem, so that a change in the population can compromise the survival of everything around them. On the other hand, insects called "pests" are those insects observed in systems and whose populations cause damage to crops. Although both beneficial insects and pest insects are part of any ecosystem and are also present in human-managed systems. Humans combat these pests using insecticides, which are chemical compounds used to kill insects. They are usually very specific since the product only affects the organism it damages, leaving the rest of living beings and the environment unharmed. And they have low toxicity to humans and animals.

The most common way in which birds are exposed to insecticides is through ingestion by mistaking, for example, a pesticide granule for a seed, or indirectly, by consuming contaminated prey (insects). Birds may also ingest pesticide residues when they trim their feathers with their beaks or may drink or bathe in contaminated water. It should be noted that it also depends on the toxicity of the chemicals, the magnitude and duration of exposure. The effects can range from death due to poisoning to a variety of effects such as weakening of eggshells, deformation and slow growth of chicks, lack of appetite, weight loss, immune system damage, hormonal disruption. In addition, insect-eating birds are at a loss when insecticides cause a drop in the number of insects available, especially when they have chicks to feed.

Which type of white blood cell is activated by antigens that are bound to antibodies?
monocytes
eosinophils
basophils
neutrophils

Answers

Answer:

basophils

Explanation:

Basophils are a class of white blood cells known as granulocyte, which also include neutrophils, eosinophils, and mast cells. These cells (basophils) are generated in the bone marrow as other white blood cells. When stimulated, basophils degranulate to release histamine, proteoglycans, and proteolytic enzymes and thus mediate immune responses. This process of degranulation occurs when a specific antigen binds to the IgE receptor on the basophil. Moreover, basophils may also be activated by inflammatory mediators (e.g., complement factors such as C5a and C3a, chemokines, etc).

Answers

Answer:

is expressed roughly equally in both sporulating and nonsporulating yeast

Explanation:

A DNA microarray (also called DNA chip) is a microchip-based testing platform which can be used to analyze and compare gene expression profiles between samples. A DNA microarray contains microscopic DNA spots attached to a solid surface, where each spot corresponds to thousands of copies of a specific DNA sequence (i.e., probes). Subsequently, cDNA 'target' molecules obtained by reverse transcription from RNA are then hybridized to a microarray. This process of hybridization can be quantified by using fluorophore-labeled targets that determine the level of the expressed gene (transcript) in the target sample. In a DNA microarray, the intensity and types of color in each spot indicate the presence and level of each specific transcribed gene in the samples. In consequence, the presence of yellow spots in the DNA microarray indicates approximately equal expression levels of the corresponding gene in both yeast samples.
