Which choice is correct?

Answer:

Coral reefs are built by and made up of thousands of tiny animals that are related to anemones and jellyfish. Polyps can live individually or in large colonies that comprise an entire reef structure. At night, polyps extend their tentacles to feed.

An action potential is caused by either threshold or suprathreshold stimuli upon a neuron. It consists of four phases; hypopolarization, depolarization, overshoot, and repolarization. An action potential propagates along the cell membrane of an axon until it reaches the terminal button.

Answer:

the shoot and root systems

Explanation:

A plant is made up of two basic parts, the shoot and root systems. Within each system you will find more complex anatomy. On the shoot system, the stem, leaves, flowers, and fruit can be seen

Answer:

Primary dermal tissues, called epidermis, make up the outer layer of all plant organs (e.g., stems, roots, leaves, flowers). They help deter excess water loss and invasion by insects and microorganisms. The vascular tissues are of two kinds: water-transporting xylem and food-transporting phloem.

For a quick simple answer, it's nutrient transport.

Explanation:

Given parameters:

Displacement of the seagull  = 145m to the east

Time taken to cover the distance = 10s

Unknown:

Velocity  = ?

Solution:

Velocity is one of the physical quantities. It is the speed in a specific direction. Hence, velocity is a vector quantity having both magnitude and direction.

  So, mathematically;

           Velocity = [tex]\frac{Displacement }{Time taken}[/tex]  

         Velocity  = [tex]\frac{145}{10}[/tex]   = 14.5m/s due east

The velocity of the seagull is 14.5m/s due east

Answer:

v=d/t=v=145/10.0=14.5m per second

Answer:

pigment

Explanation:

A pigment is a substance occurring either in plant tissue or animal tissue and producing a characteristic colour, such as chlorophyll in green plants and haemoglobin in red blood.

Answer:

b) Fossils supported Darwin's ideas about

common ancestry and the relationship of

living species to fossil species.

Explanation:

Fossil remains have been found in rocks of all ages. Fossils of the simplest organisms are found in the oldest rocks, and fossils of more complex organisms in the newest rocks. This supports Darwin's theory of evolution, which states that simple life forms gradually evolved into more complex ones.

Common ancestry allows Darwin to infer what happened in the lineage leading to modern mammals. The fact that present day birds and reptiles have sutures but no live birth is evidence that sutures were present in the lineage leading to modern mammals before live birth evolved.

Fossils showed that all species are the result

Fossils showed that all species are the resultof gradual changes over time.

Fossils. Fossils provide solid evidence that organisms from the past are not the same as those found today; fossils show a progression of evolution. Scientists determine the age of fossils and categorize them all over the world to determine when the organisms lived relative to each other.

Fossils explained how species develop

Homologous features

Homologous features If two or more species share a unique physical feature, such as a complex bone structure or a body plan, they may all have inherited this feature from a common ancestor. Physical features shared due to evolutionary history (a common ancestor) are said to be homologous.different traits.

Fossils showed how humans had affected the

Fossils showed how humans had affected thetraits of organisms for thousands of years.

Evidence for early forms of life comes from fossils. By studying fossils, scientists can learn how much (or how little) organisms have changed as life developed on Earth. There are gaps in the fossil record because many early forms of life were soft-bodied, which means that they have left few traces behind.

The answer is nonliving.

Answer: Each kind of tissue has a different function

Explanation:

Our tissues are divided into four types: epithelial, connective, muscular, and nervous. The structure of each type of tissue differs from one another, which determines its function.

Answer:

See below

Explanation:

The structure of the cell is very much linked with the functions of the cell. The cardiac muscle is made of the myocardium which serves the body by providing the blood, nutrients and oxygen. The cardiac muscles appear striped when seen under a microscope.

The skin consists of the tissues and cells which are close enough to create a boundary that does not allow the entry of materials and pathogens inside the body.

Hence, the function and the morphology of the cells are somewhere related to each other.

I think that GMOs don't provide a threat to humans. According to Kurzguzat - In a Nutshell, the "pests" that are engineered into the plant aren't actually harmful to humans. This is called a BT protein and doesn't hurt humans. There were eggplants in Bangladesh that kept getting destroyed by pests, and the genetically modified plant stopped the farmers from using massive amounts of pesticides on the plants.

Answer:

Fossils generally helps in relative dating of rocks.

The Trilobites are considered the oldest in this rock sequence when we apply the principle of superposition of strata.

The principle states that "in an undeformed/undisturbed sequence of rock, the oldest is always at the bottom while the youngest is on top" .

This principle therefore explains why the Trilobites at the base are considered the oldest.

Answer:
