The acceleration of an object is measure by its change in velocity per unit time. The equation for acceleration is: a =v/t. Acceleration is represented by 'a'. Velocity is represented by 'v'. Time is represented by 't'. Rearrange the equation to solve for time.

Answers

Answer:

t=v/a

Explanation:

To solve for Time

Since acceleration is change in velocity/time

a=v/t

Cross multiply

a×t=v

at=v

Divide both side by a since we want to find Time

at/a=v/a

t= v/a

The arrows in a food chain show: a Who eats who b Heat energy being lost c The movement of energy between organisms d The route of food to the shops

Answers

Answer:

c The movement of energy between organisms

Explanation:

Pyramid of energy is a model used to depict the flow of energy from one trophic level or feeding level to the next in an ecosystem. It's a diagram that compares the energy used by organisms at each trophic level of the food chain. The pyramid of energy must never be inverted or turned upside down.

The units used in the construction of pyramids of energy is kilocalories (kcal) or energy per area per time (Jm-²year-¹).

This ultimately implies that, the arrows in a food chain show the movement of energy between organisms such as from producers which are autotrophs or self-feeders such as plants to the tertiary consumers.

Furthermore, a list of the types of organisms in an eco pyramid are;

I. Producers: these are autotrophs or self-feeders such as plants.

II. Primary consumers: these are herbivores that typically feed on plants such as a goat or deer.

III. Secondary consumers: these consists of carnivores that typically feed or eat flesh such as lion, tiger, cheetah, etc.

IV. Tertiary consumers: these are higher predators such as humans that aren't normally fed on by other organisms in the ecosystem.

Answer: The arrows in a food chain show (The movement of energy between organisms). The correct option is C.

Explanation:

In an ecosystem, a food chain shows the transfer of energy and nutrients ( food) from organisms to organisms in a feeding pathway. Instead of giving functional group names such as primary producer, primary consumer and so on, in a good chain, the organism at each step is identified. Thus,

Grass-------> Zebra ---------> lion

(Primary (Primary ( secondary

producer). consumer) consumer)

this is an example of a simple food chain in a grassland ecosystem. This ARROWS represented above shows the direction of energy flow through an ecosystem.

Furthermore, the grass traps solar energy and stores it as chemical energy in the food made during photosynthesis. When eaten by Zebra, which is the primary consumer, the energy stored in the grass is transferred to the consumer. This transfer is inefficient as some of the stored chemical energy is lost as heat. When the zebra is eaten by a Lion,which is the secondary consumer.

When a single species, such as ancestor of the Galapagos finches, has evolved into several different forms that live in different ways we say that_ has occurred.
A.adaptive radiation
B.coevolution
C.mass extinction

What are the negative assay results?

False-negative blocks haven't received as much attention as false positives, but they can lead to misdiagnosis and improper treatment candidate selection. Based on the failure of local anesthetic infiltration to relieve the pain from facet joint capsular distention, research on 15 volunteers who had MBBs with local anesthetic or saline and capsular distention estimated the rate of false-negative blocks to be 11%.

It was determined that "aberrant innervation" was a likely explanation for some instances of unsuccessful RF denervation in IA block responders. Vascular uptake is regarded to be one of the main sources of false-negative blocks. According to reports, this can vary from 6% to 30% per level. rates of 3.9% at cervical levels, 3.5% at lumbar levels, and 0.7% at thoracic levels, according to one research.

According to one study, even if the needle is relocated when vascular uptake happens, analgesia will only be experienced 50% of the time. Digital subtraction angiography has been demonstrated to increase the detection rate and is the most reliable method of identifying vascular uptake. Failure to distinguish between procedure-related discomfort and baseline pain, as well as missing a target nerve or nerves, are other potential reasons for false-negative blocks.

Therefore, a false negative result could be the result of low concentration.

As surface water in a lake cools from 4 °C to 0 °C, the water expands and becomes less dense. Why is this change in the water beneficial to the organisms living in the lake? As the water cools to freezing, spaces form between water molecules, providing microhabitats for small organisms. Frozen surface water insulates the water below it, maintaining a habitat where organisms can overwinter. Cooler water is less viscous than warmer water, making it easier for organisms to move through the water. Less dense water holds more dissolved compounds, keeping water from freezing so organisms survive winter.

Answers

Answer:

As the water cools to freezing, spaces form between water molecules, providing microhabitats for small organisms.

Explanation:

This change in the water is beneficial to the organisms living in the lake because the water which freezes formed spaces between water molecules, that providing microhabitats for small organisms. The cold temperature causes formation of ice crystals on the surface of water which work as an insulator whereas the lower part of the water remain warm and the organisms can survive in that environment.

B. Different genes are expressed due to their environment.

Explanation:

I think it's this one because it makes the most sense, but I'm still not sure sorry

Answer:

B. Different genes are expressed due to their environment.

Explanation:

Some identical twins can have different heights and weights. This is because height and weight are controlled by what you eat as well your DNA. Differences in diet can start earlier than you might imagine. When the twins are growing inside the uterus, there can be differences in how well they connect to the placenta.

Proteins secreted by Gram-negative cells face multiple obstacles, including _____. Multiple choice question. moving across the periplasmic space underlying the thick peptidoglycan layer of the cell wall moving across the plasma membrane moving across the plasma membrane and the thick peptidoglycan layer of the cell wall moving across both the plasma membrane and the outer membrane

Answers

Answer:

moving across both the plasma membrane and the outer membrane

Explanation:

Gram-negative bacteria are bacteria that have a plasma membrane, a thin peptidoglycan layer, and an outer membrane (the space between the plasma membrane and the outer membrane is known as periplasm). Moreover, Gram-positive bacteria exhibit neither outer membrane nor periplasmic space and are surrounded by thick layers of peptidoglycan. Gram-negative bacteria have developed different protein secretion systems (types I–VI and type VIII) in order to secrete proteins into the extracellular space. For such purpose, the XcpQ protein (which is an outer membrane protein from the secretin family) participates in different transport processes in Gram-negative bacteria.
