Answer: C. They have vascular tissue such as xylem and phloem and reproduce with spores.

Explanation: This is the correct answer for Pennfoster.

Answer:

The answer is C.

Explanation:

Mosses are the category of plants that do not have vascular tissue or seeds. Ferns do not have seeds but do have vascular tissues. Angiosperms and gymnosperms have vascular tissue and seeds. Seedless vascular plants, which include club mosses, horsetails, and ferns, have vascular tissues. These tissues allow fluids to travel through the plant. Xylem is a specialized plant tissue that carries water from the roots throughout the rest of the plant, and phloem carries nutrients and sugars. You can see these tissues in the cross-section tissues of a vascular plant shown below. Although ferns have vascular tissue, they still reproduce using spores, and not seeds, following the alternation of generations.

Thus, the replica of TAGGTAACT would be ATCCATTGA

Answer:

river

Explanation:

it is smaller than the width of a lake

The correct answer is D. River

Explanation:

Rivers are one of the most common ecosystems. A river is characterized by flowing water in which biotic factors (animals, plants, bacteria, etc.) and abiotic factors (rocks, water, minerals) interact. Also, they cross major ecosystems such as forests or rainforests.

Moreover, rivers are unique because they contain fresh rather than salt water as in the ocean, and they are always flowing while in a marsh, swamp or lake the water does not flow. This suggests the ecosystem is the photograph is a river because in this the water flows and as a result of this, there is a strong current which is possible in a river but not in a lake, marsh or swamp.

Answer:

250 years

Explanation:

The Atlantic Ocean is not static, but instead it is very active, and it is actually spreading from its central part. In its central part, this ocean has a mid-ocean ridge. This basically means that there is constant formation of new crust from the magma that comes out, and the old crust is pushed sideways as the new one is formed. On an annual level, the mid-ocean ridge is spreading out by an estimated 0.02 meters, thus that is how much the Atlantic Ocean is spreading out each year. In order to get to the result as to how many years are needed for the Atlantic Ocean to spread 500 cm, we just need to multiply the annual spreading with the number of cm in question:

0.02 x 500 =250

Thus we get a result of 250, meaning that in 250 years the Atlantic Ocean will spread out 500 cm in total.

Answer:

200 years.

Explanation:

The Atlantic Ocean widens by 2.5 centimeters every year. So,

[tex]\frac{2.5 cm}{1 year}[/tex] (2.5 cm/1 year) = [tex]\frac{500 cm}{x year}[/tex] (500 cm/ x year)

Cross-multiply to solve for x:

x(2.5) = (1) (500)

x = 500 ÷ 2.5

x = 200 years.

It will take 200 years for the Atlantic Ocean to grow by 500 centimeters.

An order is subdivided into several families.

In biological classification, the hierarchy of classification goes from broadest to most specific, with the order being a higher taxonomic rank than a family. The taxonomic hierarchy, commonly used in biology and ecology, follows this order: Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species.

An order is a rank or category that includes one or more related families. It groups together organisms that share some common characteristics but are more closely related to each other than to members of other orders. Within an order, the families share certain similarities, but they also have enough differences to warrant separate classification.

For example, let's consider the order Carnivora, which includes animals like cats, dogs, and bears. Within the order Carnivora, there are several families, such as Felidae (cats), Canidae (dogs), Ursidae (bears), and others. Each family represents a more specific group of related species within the broader order Carnivora.

Taxonomic classification is essential for organizing the vast diversity of life on Earth and understanding the evolutionary relationships between different groups of organisms. It allows scientists to study and categorize species based on shared characteristics and evolutionary history. Subdividing orders into families is just one step in this systematic approach to classifying and understanding the rich tapestry of life on our planet.

Answer: the nucleous

Explanation:

The organelle that stores most of a cell's DNA is the nucleus.

The nucleus is a membrane-bound organelle found in eukaryotic cells, and it serves as the control center of the cell. Within the nucleus, the genetic material, which is in the form of DNA (deoxyribonucleic acid), is organized into structures called chromosomes. These chromosomes contain the genes that carry the instructions for various cellular processes and traits.

The DNA in the nucleus is responsible for the transmission of genetic information from one generation to the next and plays a crucial role in protein synthesis and cellular functioning. The nucleus also regulates the expression of genes and controls the replication and transcription of DNA.

Answer:

The Teeth

Explanation:

Carnivores have teeth that are more for ripping and shredding a prey's flesh. They are sharper. Herbivores have more square and flat teeth for mashing leaves and grass.

To determine if a fossilized animal was a carnivore or herbivore, examine its teeth. Carnivores have sharp, pointed teeth for tearing flesh, while herbivores have flat, broad teeth for grinding plant material. These dental adaptations reflect their dietary habits.

Carnivores typically have sharp, pointed teeth designed for tearing flesh. These include canines for gripping and incisors for shearing. Their molars are often sharp, known as carnassials, which work like scissors. Examples include lions and wolves.

In contrast, herbivores possess flat, broad teeth adapted for grinding plant material. They have well-developed molars and premolars suitable for chewing, with incisors that are often used for cutting plants.

Examples include cows and horses. The differences in dental structures reflect their diets and provide insight into the ecological roles these animals played.

Answer:

[tex]1000[/tex] cubic centimeters

Explanation:

Given -

Width of the book is equal to [tex]10[/tex] cm

Length of the book is two times the width of the book

Which means length is equal to

[tex]2 * 10\\= 20[/tex] cm

Height of the book is half of the width of the book

Which means height is equal to

[tex]0.5 * 10\\= 5[/tex] cm

Volume of the book is equal to the product of length, width and height

[tex]= 10 * 20* 5\\= 1000[/tex] cubic centimeters

The volume of the book is 1000 cm³.

To find the volume of the book, we need to multiply the width, length, and height. The width is given as 10 cm. The length is 2 times the width, which is 20 cm. The height is half of the width, which is 5 cm.

Therefore, the volume of the book is 10 cm * 20 cm * 5 cm = 1000 cm³.

Answer:because of the amount of movement of tectonic plates along the area

Explanation:

The Ring of Fire, also referred to as the Circum-Pacific Belt, is a path along the Pacific Ocean characterized by active volcanoes and frequent earthquakes. Its length is approximately 40,000 kilometers (24,900 miles). It traces boundaries between several tectonic plates—including the Pacific, Juan de Fuca, Cocos, Indian-Australian, Nazca, North American, and Philippine Plates.

Seventy-five percent of Earth’s volcanoes—more than 450 volcanoes—are located along the Ring of Fire. Ninety percent of Earth’s earthquakes occur along its path, including the planet’s most violent and dramatic seismic events.

The abundance of volcanoes and earthquakes along the Ring of Fire is caused by the amount of movement of tectonic plates in the area. Along much of the Ring of Fire, plates overlap at convergent boundaries called subduction zones. That is, the plate that is underneath is pushed down, or subducted, by the plate above. As rock is subducted, it melts and becomes magma. The abundance of magma so near to Earth’s surface gives rise to conditions ripe for volcanic activity. A significant exception is the border between the Pacific and North American Plates. This stretch of the Ring of Fire is a transform boundary, where plates move sideways past one another. This type of boundary generates a large number of earthquakes as tension in Earth’s crust builds up and is released.

Answer:

The correct answer is option A: "photosynthesis".

Explanation:

Photosynthesis is the process by producers, such as plants and some bacteria, at which they produce glucose from carbon dioxide and water using sunlight as fountain of energy. Oxygen is a byproduct of photosynthesis, which is used by aerobic organisms to perform cellular respiration. The formula herein included represents the process of photosynthesis, since the combination of carbon dioxide (CO2) and water (H20), produces glucose (C6H1206) and oxygen (02).

Answer:

Photosynthesis is important to living organisms because:

Explanation:

Photosynthesis is commonly called the process "by which plants produce their own food," however, this is not the only function of this process, since, in addition to absorbing carbon dioxide from the environment (which living beings we expel through respiration), it releases oxygen into the environment which is essential for our subsistence as it is the element that our body requires and that we acquire through respiration.

Answer:

I would say that its they are descendant of a common ancestor. DNA shows that our species and chimpanzees diverged from a common ancestor species that lived between 8 and 6 million years ago.

Explanation:

The answer is:

The balanced equation is:

[tex]4Fe+3O_2=2Fe_{2}O_{3}[/tex]

Finding a balanced equation of a reaction means making equal the number of atoms for both reactants and products sides, according to the conservation mass law, the mass is always conserved, so, we need to make both quantities of atoms/molecules match.

So, we are given the following reaction:

[tex]Fe+O_2=Fe_{2}O_{3}[/tex]

For the reactants, we have 1 molecule of Fe and 2 of O

For the  products, we have 2 molecules of Fe and 3 of O

So, balancing the Oxygen, we have:

[tex]Fe+3*O_2=Fe_{2}O_{3}[/tex]

[tex]Fe+3O_2=Fe_{2}O_{3}[/tex]

Now, there are 6 atoms of oxygen in the reactant, let's multiply the product by 2 in order to make both sides match, so:

[tex]Fe+3O_2=2*(Fe_{2}O_{3})[/tex]

[tex]Fe+3O_2=2(Fe_{2}O_{3})[/tex]

Now, we can see that there are 6 atoms of Oxygen in both sides, but there are 4  atoms of Fe in the products and just 1 atom in the reactants, so, we need to multiply the Fe by 4.

So, balancing the Iron (Fe) we have:

[tex]4*Fe+3O_2=2(Fe_{2}O_{3})[/tex]

[tex]4Fe+3O_2=2Fe_{2}O_{3}[/tex]

Hence, we can see that we now have the same number of atoms on both sides, we have:

[tex]Fe_{reactants}=4\\O_{reactants}=6\\Fe_{products}=4\\O_{products}=6[/tex]

Therefore, the equation is balanced.

[tex]4Fe+3O_2=2Fe_{2}O_{3}[/tex]

The letter A represents spindle in the diagram. Therefore, option (D) is correct.

The mitotic spindle or achromatic mitotic apparatus of a cell is a bipolar assemblage of microtubules that is inflated in the center.

The achromatic spindle, meiotic spindle, or mitotic spindle is a set of microtubules that flow from centrioles during cell division, from chromosome centromeres to pole centrioles. The centrosome (animal cell) or microtubule organising center (plant cell) produces them.

During metaphase, all chromosomes are placed on the equatorial plane of the dividing cell, and during anaphase, each of the two chromatids in which a chromosome is divided is propelled to one of the two poles of the cell by microtubules. The mitotic or achromatic spindle microtubules are anchored in chromosome centromeres by proteinaceous leaves called kinetochores.
