Compare and contrast the TWO classes of "seeded "plants.​

Answers

Answer 1

Answer:

The seed plants are often divided arbitrarily into two groups: the gymnosperms and the angiosperms. The basis for this distinction is that angiosperms produce flowers, while the gymnosperms do not.

Explanation:

The seed plants are often divided arbitrarily into two groups: the gymnosperms and the angiosperms. The basis for this distinction is that angiosperms produce flowers, while the gymnosperms do not. This is poor form, since it defines the gymnosperms by the absence of a character, and not by any features that the organisms actually share. The gymnosperms do share a number of features, but, as should be obvious from the above cladogram, they are not more closely related to each other than to the angiosperms (Anthophyta). The features shared by gymnosperms were likely present in the early ancestors of the flowering plants as well. It should also be noted that the "progymnosperms" are represented by a box of a different color, in order to make it clear that they are not actually seed plants, but rather are included here because they are believed to be the closest relatives of the seed plants.

Systematics within the seed plants is poorly understood. Part of the problem is that most of the major groups have gone extinct, and several of the groups alive today consist primarily of plants with highly derived morphologies. The above cladogram is based largely on the work of Jim Doyle, a professor at UC Davis, and Michael Donoghue, currently at Harvard, and is therefore somewhat preliminary. It includes some questionable groupings not explicitly supported in their papers.

Name some useful products or materials that are carried by blood.​

Answers

Answer:

Blood brings oxygen and nutrients to all the parts of the body so they can keep working. Blood carries carbon dioxide and other waste materials to the lungs, kidneys, and digestive system to be removed from the body. Blood also fights infections, and carries hormones around the body.

The process of forming ATP is? A) Digestion. B) Cellular Respiration. C) Metabolism. D) nutrition.

Answers

Answer:

[tex]\boxed {\boxed {\sf B. \ Cellular \ respiration}}[/tex]

Explanation:

First, let's analyze each process.

A. Digestion

This is the process of breaking down food.

B. Cellular respiration

This is the process of converting glucose and oxygen to carbon dioxide, water, and ATP.

C. Metabolism

This isn't really a process. It's the collection of all the chemical reactions in the body to keep the body functioning.

D. Nutrition

This term also isn't a process. Nutrition involves food, nutrients, and health.

We are looking for the process that forms ATP. Therefore, the best answer choice is B. Cellular respiration

The process of forming ATP is Cellular Respiration. Therefore option B is correct.

The process of forming ATP (Adenosine Triphosphate) is primarily through Cellular Respiration.

ATP is the main energy currency in cells, providing the energy needed for various cellular activities.

Cellular respiration is a series of metabolic reactions that occur in the mitochondria of cells, where organic molecules (such as glucose) are broken down and oxidized to release energy.

This energy is used to synthesize ATP from ADP (Adenosine Diphosphate) and inorganic phosphate (Pi).

Through cellular respiration, cells efficiently convert the energy stored in food molecules into a readily usable form of energy (ATP).

Which powers essential cellular processes, including muscle contraction, active transport, and synthesis of macromolecules.

Therefore option B Cellular Respiration is correct.

what does the process of breaking and reforming bonds allow cells to make?

Answers

Synthesis releases energy because the molecules bond to form a stable configuration and therefore give up energy. The bonded molecules have a lower energy level than free molecules and are held in the new bond.

The process of breaking bonds between molecules and the making or reforming of bonds encompasses chemical processes which allows the creation or formation of new molecules.

When bond is broken such that a certain element splits from a compound, new molecule is formed. Endothermic processes required energy to break bonds between atoms.

Bond making on the other hand are exothermic processes which involves merging of bond accompanied by the release of energy to form new molecules.

Therefore, bith Endothermic and exothermic processes allows cells to make new molecules.

Read the excerpt from "Bone Detective," by Lorraine Jean Hopping. While the dentist worked on the tiger’s teeth, Diane made an alginate impression of one of its huge paws. Then, the dentist used two cupped hands to pull the tongue out of the big cat’s mouth. The heavily muscled organ was almost as long as her foot. With the dentist still holding the tiger tongue in both hands, Diane quickly went to work. The pink surface was rough, like sandpaper, but floppy and wet. She coated the top with alginate and waited for it to set. Her 15 minutes were almost up. The tiger, so calm and soft, would soon wake up and be dangerous again. Slowly and carefully, Diane peeled off the soft impression to avoid tearing it. Based on this excerpt, what is the author’s attitude toward Diane France? The author feels Diane is rough and impatient in her work with the tiger. The author feels Diane is skillful and careful in her work with the tiger. The author feels Diane is anxious and distracted in her work with the tiger. The author feels Diane is light-hearted and humorous in her work with the tiger.

If a patient has a medical condition that causes his cells to absorb fewer than normal __________ molecules, this patient would likely feel very tired. Explain your reasoning

I think protein because if yuu don’t have enough yuu can feel tired Nd not energize .

You feel exhausted when your body is oxygenally depleted. When your lungs are unable to breathe in and out properly, fatigue sets in more quickly.  Thus, option A is correct.

What is the less absorption of oxygen in cell to indicate?

Necrosis, or cell death, occurs when glucose and oxygen are not provided to cells. It's interesting to note that cells can survive hypoxia.

According to the early research showing that acute oxygen deprivation triggers the intrinsic apoptotic pathway, there is a reduction in the potential of the mitochondrial membrane.

This starts a nasty loop. You're less likely to exercise when you're feeling tired as a result of a lack of oxygen.

Therefore, Numerous factors, such as a reduction in red blood cell concentration or a reduction in hemoglobin's oxygen saturation, can lead to a reduction in oxygen-carrying capacity.

ln certain species of plant, one purebred
variety has hairy leaves and another pure-
bred variety has smooth leaves. A cross of
the two varieties produces offspring that all
have smooth leaves. Predict the ratio of
phenotypes in the F2, generation.

Answers

Answer:

If crossing plants with hairy leaves and smooth leaves produces plants with smooth leaves in F1, the phenotypic ratio of plants with smooth leaves:hairy leaves in F2 will be 3:1.

Explanation:

It is assumed that, if the first descendants of this cross presented smooth leaves, this represents the dominant characteristic.

If in the crossing of two plants, the parental generation consists of two pure plants for the characteristic aspect of the leaf, one with hairy leaves (s) and another with smooth leaves (S), the first filial generation (F1) will be of hybrid plants with a phenotype of smooth leaves (Ss), which represents the dominant characteristic.

Parental Generation:

Smooth leaves SSHairy leaves ss

Punnett Square  F1

Alleles      S        S

s              Ss       Ss

s              Ss       Ss

F1 : 100% plants with smooth leaves Ss

The second filial generation (F2) results from the crossing of F1 individuals, so:

Punnett Square  F2

Alleles      S        s

S              SS      Ss

s              Ss       ss

The result of the offspring in F2 is:

Genotype

Pure smooth leaves SS 25%Smooth hybrid leaves Ss (heterozygous) : 50%Pure hairy leaves ss:  25%

Genotipic ratio: pure smooth leaves:hybrid:pure hairy leaves  1:3:1

Phenotype

Smooth leaves SS + Ss:  75%Hairy leaves  ss: 25%

So the phenotypic ratio of smooth leaves: hairy leaves will be 3:1.

Sea turtles spend most of their lives at sea feeding on jellyfish. When it is time to lay their eggs, mature females come ashore. They dig nests in the sand along the coast, lay their eggs, and then return to the sea. The data below show the changing sea levels since the late 1800s.


If the current trend shown in the graph continues, what prediction is most likely regarding the future of sea turtles?


a. Fewer jellyfish will wash up on the beach for the turtles to feed on.


b. More predators will be found on the beaches to threaten the baby turtles.


c. The baby turtles will have to travel farther to reach the ocean.


d. The beaches on which turtles currently lay their eggs may go underwater.

Answers

Answer:

d. The beaches on which turtles currently lay their eggs may go underwater.

Explanation:

According to the graph, the beaches on which turtles currently lay their eggs may go underwater due to increase sea level with the passage of time. In the graph, we can see that sea level increases from 1880 to 2014 and the main reason for this increase is the climate change. Due to global warming the water present on the glacier starts melting and thus increase in sea level occurs so the beaches on which turtles currently lay their eggs may go underwater.

Answers

Answer:

Cells such as chloroplasts are self replicating

Explanation:

a chloroplast is not a cell its an organelle.

Cell Theory is a scientific theory proposed by Schwann in the year 1839. The cell theory has primary three postulates, which are used to describe the functioning of cells.

The correct answer is:

Option D. Cell parts such as chloroplasts are self-replicating.

The postulates of the cell theory are:

1. The cell theory states that all living cells arise from pre-existing cells.

2. The cells are the basic structural and functional unit of life.

3. The hereditary information is passed on from cell to cell, and the energy flows within the cell.

Thus, the statement that is not a part of cell theory is that chloroplast are self-replicating.

Explanation: Modern taxonomists seek to employ classification schemes that are consistent with the underlying evolutionary relationships among species. As shown below, phylogenetic analyses present a way to test existing Linnaean classifications (some of which predate widespread acceptance of the fact of evolution) and to determine which classifications are consistent with evolutionary history, and which require modification.
