Contrast the flow materials in xylem and phloem

Biology
2 answers:
zimovet [89]3 years ago

To easy remember it,
Phloem, has the (f) sound, so it carries food and nutrition like sugars all around the plant, up and down movwment.
while Xylem carries water and minerals, from down the soil up to the plant, only up movement.

Another method to remember it is to imagine that The Phloem is like the King in checkers it can move forwards or backwards unlike normal pieces which are restricted to moving only forwards. To cap:

Phloem can move Upwards and Downwards

Xylem can only move upwards.

if I confused anyone keep in mind that most plants stand up and a checker board is flat, meaning that they are on different planes thus require different wording. Hopefully this is also helpful for remembering the distinction between the two.

A food that supplies two grams each of fat, carbohydrate, and protein delivers_____total calories.
Oliga [24]

Answer:

34 calories

Explanation:

One gram of carbohydrates provides total= 4 calories.

2 grams of carbohydrates would provide= 4 x 2 = 8 calories.

One gram of protein provides total= 4 calories.

2 grams of protein would provide= 4 x 2 = 8 calories.

One gram of fat provides total= 9 calories.

2 grams of carbohydrates would provide= 9 x 2 = 18 calories.

Total calories from food that gives two grams each of fat, carbohydrate, and protein= 8 + 8 + 18 = 34 calories.

When does a zygote become an embryo?
Andre45 [30]

Answer:

Explanation:

The transformation of a zygote into an embryo adheres both to nature and to nurture: not only genetics but also environment determines the outcome. This idea has assumed many forms. A territory in the early sea urchin blastula contains clones of founder cells, and each clone contributes exclusively to one territory (Cameron & Davidson, 1991). Both the lineage of a founder cell, i.e. its nature, and the position of a founder cell, which determines how it is nurtured, contribute to its fate. Fertilisation, the topic of the first Forum, fixes the genes; interblastomere communication, the topic here, regulates gene expression. Blastomeres communicate like any other cell – via ligand-receptor interactions and through gap junctions. Saxe and DeHaan review these mechanisms. The definition of ligands and receptors becomes broadened in this context, and cell adhesions as well as gap junctions enter into the story. In spite of these entanglements, it appears that nature uses the same sorts of mechanisms to get cells to specialise that she uses to keep them talking. Thus, neurons and glial cells signal to one another via glutamate receptors and gap junctions (Nedergaard, 1994). Likewise, we expect neurotransmitters (and neurotransmitter transporters) to help signal differentiation. The biophysicist may ask whether electrical properties also play a role, but that we reserve for another Forum. If gap junctions figure in development as fusion pores that pass small molecules and electrical signals between blastomeres, another parallel suggests itself. Brian Dale asked in the first Forum: How does a spermatozoon activate an oocyte? This question, which concerns gamete communication, has produced two schools of thought and remains controversial (Shilling et al., 1994). Do sperm activate oocytes via contact-mediated mechanisms or through fusionmediated mechanisms? Or do both mechanisms occur, as they appear to in development?

The part of the brain whose anatomy is most similar to the spinal cord is the _______.
sdas [7]
Brainstem.

The brainstem is the portion of the central nervous system that's located between the spinal cord and the d<span>iencephalon and it occupies the posterior cranial fossa in front of the cerebellum. It is divided into three parts: the rachidian bulb, the pons, and the midbrain.
It's in the brainstem that can be found the commanding nucleus of the most basic homeostatic mechanisms such as heart rate, breathing, and n</span><span>ociception.</span>

coronary heart disease is much less common in some countries than it is in the united states. What facts might account for this
Lemur [1.5K]
Just based on common evidence....I think it is because of all the fast food restaurants, we work a lot therefore we resort to eating out, fast food places have dollar menus, and we also use motorized transportation to much as well.  Most of the cities are not equipped with things like bicycle lanes.
