Answer:
Ideally, the experimental and control groups are identical. As much as possible, the two groups should overlap in every characteristic.
Explanation:
At the beginning of your study, you need your two groups to be as statistically similar as is humanly possible. That way, when you control for other variables, you can reasonably attribute any statistically significant differences at the end of the study to your intervention.

Are the anomalies the same thickness along all ridge segments Why or why not?
plz help :D
Answer:
The equivalent magnetization (EM) and mantle Bouguer anomaly (MBA) were calculated along the ultraslow-spreading Mohns Ridge axis in the Norwegian-Greenland Sea. The magnetic anomaly and the associated EM were compared with the bathymetry, MBA, seismically determined crustal structure and geochemical data at both the inter-segment scale (>60 km) and the intra-segment scale (20–60 km). At the inter-segment scale, the magnetic highs at the segment centers are independent of the MBA. Of the 13 segments, 9 with magnetic anomalies >700 nT coincide with axial volcanic ridges identified from multibeam bathymetry maps, which suggests that the magnetic highs at the segment centers may be more associated with the extrusive lavas rather than the amount of magma supply. With few exceptions, the magnetic anomaly lows associated with MBA highs at the segment ends increase from south to north. This trend might be explained by thickened extrusive basalts and/or more serpentinized peridotites at the segment ends in the north. At the intra-segment scale, the most prominent features are the decreases in the magnetic anomalies and associated EMs from the segment centers to the ends. The intra-segment magnetic anomalies have positive and negative correlations with the bathymetry and MBA, respectively. The magnetic signal modeled by the seismically determined layer 2A with an assumed constant magnetization is remarkably consistent with the observed magnetic anomaly, which strongly suggests that the thickness of the extrusive basalts dominates the magnetic structure in each segment along the Mohns Ridge. In general, the thickness of the extrusive basalts dominates the magnetic structure along the Mohns Ridge, whereas the contributions from serpentinized peridotites may be significant at the segment ends and may produce long-wavelength magnetic variations. The magnetic data can be used as an indicator of the thickness of the extrusive basalts within segments along the ultraslow-spreading Mohns Ridge.

In the energy pyramid, the snake is classified as a
A)
consumer
B)
decomposer
herbivore.
D)
producer.
In the energy pyramid, the snake is a consumer. Therefore, the correct statement is option A.
What is a food chain?A food chain is a series of organisms in an ecosystem where the energy flows from one organism to another organism and each organism serves as food to another organism. For example, plant is consumed by herbivore. The herbivore is then consumed by a secondary consumer, which is in turn consumed by a tertiary consumer.
In an energy pyramid provided, the snake is classified as a consumer. Consumers are organisms that consumes other organisms to obtain energy. Snakes are carnivorous animals that consume other animals, such as rodents, birds, etc. Therefore, they are consumers in the energy pyramid.
Decomposers are organisms that feed on dead organic matter, while herbivores are animals that consume only plants, and producers make their own food.
Therefore, snake is a consumer in the energy pyramid.

Considering the drifting of continents, how do you explain the abundance of marsupials and the absence of native placental mammals in Australia
Answer:
this phenomenon is a natural consequence of evolutionary processes and continental drift
Explanation:
Marsupials are mammals in which newborn offspring are carried in a pouch of the female (mother) body. On the other hand, placentals are mammals that complete embryo development in the mother's body, in the placenta. All the extant marsupials are endemic to Australia and the Americas. It has been shown that marsupials diverged (evolved) in South America, Australia and Antarctica when these landmasses were joined. In Australia, marsupials evolved to fit an ecological niche, which can be attributed to geographic isolation due to continental drift, while placental mammals are relatively recent and more scarce (mainly bats and rodents) within this region.

numerous pits and serving a mechanical function only are called -
Collenchyma
O
Xylem
O
Aerenchyma
O
Sclerenchyma
Answer:
The correct answer is - Sclerenchyma
Explanation:
Sclerenchyma are the dead cells with narrow lumen lignified cells. These dead cells has numerous pits that helps in trading the various substances to neighboring cells. At matuarity, hese cell lack the protoplast so therefore called dead cells .
Sclerenchyma cells are lignified which makes them thick and these cells help in the supporting the plants. These cells are impereable to almost everything gases, substances and many more.

Answer:
This question lacks options: 1) keystone species. 2) symbiotic species. 3) sympatric species. 4) allopatric species. 5) refugistic species. The correct answer is 1) keystone species.
Explanation:
Keystone species are the species that have a more important effect on the ecosystem than expected for its low biomass, exerting a direct influence on the others, that is, a key species can have different effects on its ecosystem or on other species with those that cohabit. Among them are: Modification of the landscape, source of food, generators of shelter, altering ecological processes. This makes their presence very meaningful.

The table below shows salinity tests from coastal Louisiana following a salt water influx during hurricanes Katrina and Rita. If efforts are not made to reduce the salinity in these areas, what is the most likely long term effect?
A growth in the population of salt-intolerant types of plants
A shift in species composition to less salt-tolerant plants
A shift in species composition to more salt-tolerant plants
An increase in the diversity of salt-intolerant plants
A shift in species composition to less salt-tolerant plants is the most likely long term effect.
What are the characteristics of salt-tolerant plants?The salt tolerance test is performed using Tryptic Soy Broth with added sodium chloride (regular table salt) to create an overall salt concentration of 6.5%. It is a selective medium which tests the ability of an organism to survive in a salt-rich environment.
The salt tolerance of a plant is often defined as the degree to which the plant can withstand, without significant adverse effects, moderate or high concentrations of salt in water on its leaves or in the soil within reach of its roots.
Hypersensitivity to catecholamines may be the cause of salt sensitivity. A low sodium concentration in saliva deserves further study as a simple screening test to identify salt-sensitive subjects.

How is the DNA sequence AATTA replicated in a new strand during semiconservative replication?
Answer:
According to the semi-conservative DNA replication, the AATTA sequence is transcribed into a new strand as TTAAT, taking into account the complementarity of nitrogenous bases.
Explanation:
Semi-conservative DNA replication means that two molecules are obtained from a double-stranded DNA molecule, each with an original strand and a new strand.
The DNA is composed of sequences of nitrogenous bases, which are adenine (A), guanine (G), thymine (T) and cytosine (C). The bases of one chain are matched with the bases of another, according to the complementarity of nitrogenous bases, where:
Adenine is complemented with Thymine A=TGuanine is complemented with Cytosine G≡CThen, for the sequence AATTA of the strand DNA mold, the sequence on the new strand would be complementary, i.e., TTAAT.

1. The lack of clean water can affect people's lives because people use water for everyday things. If people do not shower with clean water, then what is the point of showering at all? Also, people use water to cook, so if people are using dirty water then you could get sick. Some people do not buy water, so you would have to boil the water each time you want to drink it. This is how a lack of clean water could affect people's lives.
2. There are many things that could change people's lives positevly. For example, if you move to a new state where it is warmer. If you go to a new school you could make new friends.
