Can someone please help me with these two:
1. Blood is at it's highest pressure just when it leaves the heart. Why do you think so?
2. The blood in an artery flows faster and at higher pressure than blood in veins. Why so?
Answer:
1.Blood pressure can be defined as the pressure of blood on the walls of the arteries as it circulates through the body. Blood pressure is highest as its leaves the heart through the aorta and gradually decreases as it enters smaller and smaller blood vessels (arteries, arterioles, and capillaries).
2. The more rounded the lumen, the less surface area the blood encounters, and the less resistance the vessel offers. Vasoconstriction increases pressure within a vein as it does in an artery, but in veins, the increased pressure increases flow.

Explain how the following events could be important in the formation of a new community of living things:
a) Fish-eating birds land on rocky islands
b) A coconut is washed up on a beach
c) An especially high tide washes seaweed onto a sandy beach
Answer:
The secondary succession.
Explanation:
It one of the ecological successions of a plant life that take place on the primary or disturbed system as the succession occurs in the preexisting soils as here the preen of the rocky island and the sandy beach is considered to be the primary succession where the coconut is washed by the high tides along with the seaweed.
The secondary succession thus starts to form with the interaction of the and beach as the coconut will continue and grow in the sandy beach as it will get nutrient and moisture firm the soil and gradually develop into a large island of coconut palm trees and thus the rocky beach will get converted to a secondary living community.
You are walking through a mixed evergreen-deciduous forest, where approximately 10 percent of the trees are eastern hemlocks, a species of evergreen tree that casts very deep shade on the forest understory. Interestingly, under every eastern hemlock, you find the same small herbaceous plant species. However, you never observe this species anywhere else, even though a healthy diversity of other species live throughout the forest understory. You expect the small herbaceous species to have _____ growth, _____ sexual maturity, _____ energy expended on seeds, and _____ reproduction. Please choose the correct answer from the following choices, and then select the submit answer button. Answer choices fast; early; high; no vegetative slow; late; low; vegetative slow; early; low; vegetative fast; early; low; vegetative slow; late; high; no vegetative
Answer: slow; late; low; vegetative
Explanation: Due to the casting of deep shade on the forest understory by eastern hemlock, direct sunlight and other necessities for photosynthesis and other life processes needed by the herbaceous plant species for optimum growth is being deprived.
However, coupled with the nature of these herbaceous plant species, having non-woody stems with their growth above the ground level often dieing off particularly in winter in the temperate zone, makes their growth in that kind of location to be stunted.
Thus, herbaceous plant species with slow growth rate leading to late sexual maturuty while having low expanded energy on seeds due to low photosynthetic rate and low vegetative reproduction should be expected.
Decomposers are important in the environment because they
A. convert large molecules into simpler molecules that can then be recycled
B. release heat from large molecules so that the heat can be recycled through the ecosystem
C. can take in carbon dioxide and convert it into oxygen
D. convert molecules of dead organisms into permanent biotic parts of an ecosystem
Answer:
D
Explanation:
Decomposers are important in the environment because they convert molecules of dead organisms into permanent biotic parts of an ecosystem. So, the correct option is (D).
What are Decomposers?Living organisms such as micro-organisms that convert dead plants and animals into humus are known as decomposers. Fungi and bacteria fall in this category. It recycles and converts the dead matter into humus which mixes with the soil of the forest. It provides essential nutrients to the plants. It is also known as detritivores.
There are four types of decomposers, namely
FungiInsectsEarthwormBacteriaThese types of organisms decompose or break down organic matter such as the remains of dead organisms, carrying out the process of decomposition, which occurs after the death of all living organisms.
They are also called reducers because they are able to remove or degrade dead bodies of organisms and because of their small size they are known as micro consumers.
Thus, Decomposers are important in the environment because they convert molecules of dead organisms into permanent biotic parts of an ecosystem. So, the correct option is (D).

Farmer Brown notices his tomato plants are leaning towards the front, which results in spoiling tomatoes. Briefly explain to Mr.
Brown what method he can
use prevent that from happening
Answer:
Install wood or rebar stakes at least 6 feet-tall at planting time. As the plants grow, tie the stems loosely to the stakes with twine or strips of fabric.The most common cause of leggy seedlings is lack of strong, overhead lighting. Tomato plants become long and spindly when they are reaching for the light. If the light only comes from one direction, then your seedlings not only become leggy, but will also lean towards the light.Generally speaking, in the north, tall plants such as beans, peas, and corn do best on the north side of the garden. Medium size crops such as tomatoes, cabbage, squash, pumpkins, and broccoli in the center of the garden.
Un fluido es todo cuerpo que tiene la propiedad de fluir, y carece de rigidez y elasticidad, y en consecuencia cede inmediatamente a cualquier fuerza tendente a alterar su forma y adoptando así la forma del recipiente que lo contiene. Los fluidos pueden ser líquidos o gases según la diferente intensidad de las fuerzas de cohesión existentes entre sus moléculas. Seleccione una: Verdadero Falso
Answer:
True.
Explanation:
Yes, fluids can be liquids or gases depending on the different intensity of the cohesion forces that exists between their molecules because these cohesive forces allows the molecules to attach to one another that leads to their state of matter. Cohesion forces such as hydrogen bonding and van der Waals forces are responsible for the bulk property of liquids that resisting separation from one another so due to these bonding, the molecules attach to one another on the basis of strong bonding between molecules.

What genes direct the
development or body plan of
organisms?
A. hox genes
B. beta genes
C. triage genes
Answer:
a. hox genes.
Explanation:
HOX genes have the following functions:
HOX genes are the homeobox subset.They specify the areas of the embryo's body plan along the animal head-tail axis.They are encoding Hox proteins that specify the position characteristics and ensure that the right structures form at the right position in the body.They regulate high-level executive genes, such as transcription factors and intracellular signaling molecules, which adhere, number, form, and growth to cells.The vertebrates are highly preserved.
The clusters and other genes occur uninterrupted.
Evolutionary, the heterogeneous regulatory areas between the genes most previously present are larger and more preserved than those present at the other ends of the clusters.
The characteristical feature is that these are homeodomain proteins with a highly preserved area of DNA binding encoded with homeobox gens.

Answer:
23 pairs in meiosis 1 and 23 numbers in meiosis 2.
Explanation:
There are diploid number of chromosomes means double number of chromosomes at the end of meiosis 1 while on the other hand, at the end of meiosis 2, there are haploid number of chromosome means half number of chromosomes in each daughter cell. In humans meiosis 1, there are 23 pairs of chromosomes that is diploid in nature but in the end of meiosis 2, there are only 23 chromosomes in each daughter cell which is haploid in nature.
