Autotrophs: use photosynthesis.
What are Autotrophs?
Autotrophs are living things that can make their own nourishment from inorganic resources. The roots of the terms "autotroph" are "self" and "troph," which refer to nourishment. An autotroph is an organism that can sustain itself entirely without the help of other living things.
Because they are necessary for the existence of all other life forms, autotrophs are very significant. For instance, there would be no herbivorous animals and no carnivorous creatures that consume herbivores if there were no plants that used carbon dioxide gas and sunshine to produce carbohydrates. Autotrophs are frequently referred to as "producers" because of this. They give the energy that all heterotrophs (organisms that must obtain their food from others) need in order to thrive, and they are the foundation of an ecosystem's energy pyramid.

When moving from left to right across a period, ionization energy is increasing. By which other trend is this caused?
If we see in the periodic table then we can easily see that, the first ionization gradually increases if we move left to right in the periodic table. The whole process occur due to the increase in nuclear charge, due to the result of which the valence electron more strongly bound to the nucleus. Generally the atomic radius decreases when it moves across the period, so due to which a greater attraction between the negatively charged electrons and positively-charged nucleus occurs.

Show your work here using the data in Table 1 to calculate the energy consumed by this female sea otter:
Sea otters eat 25 percent of their body weight each day in the form of sea urchins, crabs, mussels, clams, snails and other invertebrates.
1 urchin that weighs around 15 grams provides 20 calories of energy.
So,
40 urchins = 800 calories of energy.
Similarly,
1 mussel = 146 calories of energy.
So,
12 mussels = 1752 calories of energy.
And,
1 crab = 381 calories of energy
So,
4 crabs = 1524 calories of energy
Hence, the total amount of calories consumed by the sea otter is equals,
= 4076 calories of energy per day approximately.
Female otter needs about 7,500 calories per day.

Yes, a person that has no recollection of performing any unconscious act does not deserve to be punished.
It is no less unjust, if Locke is correct, to hold someone responsible for actions about which he has a distorted memory. That is, if his memory of behaviour consists of his admirable intent and the righteousness of act, then to punish him for such act is itself unjust. His biased memory makes it impossible to punish him without also acting unjustly; for he finds your punishment incongruent with his laudable behaviour.

55. cytochemical stains were performed on bone marrow smears from an acute leukemia patient. the majority of the blasts showed varying amounts of myeloperoxidase positivity. some of the blasts stained positive for chloroacetate esterase, some were positive for alpha-naphthyl acetate esterase, and some blasts stained positive for both esterases. what type of leukemia is indicated? a. lymphocytic b. myelogenous c. myelomonocytic d. erythroleukemia
In the given question where cytochemical stains were performed on bone marrow smears from an acute leukemia patient, the type of leukemia indicated is Myelomonocytic leukemia.
Cytochemical diagnosis of acute myelomonocytic leukemia
In a third group, leukemic cells contain both esterase in the same cell, and this group is thought to represent "true" myelomonocytic leukemia.
Blood and bone marrow smears from adult patients with acute leukemia were stained for esterase reactions sequentially with naphthol AS D-chloroacetate (chloroacetate esterase) followed by alpha-naphthylbutyrate (non-specific esterase). Two substrates were specific for granulocytes and monocytes, respectively.
This method allows her to distinguish between three subgroups of acute nonlymphocytic leukemia. Leukemia cells can be positive for either chloroacetate esterase or non-specific esterase, and the authors suggest that these two subsets can be divided into 'true' granulocytic leukemia and 'pure' monocytic leukemia.
In the majority of patients in this group, leukemia developed from the preleukemia stage. Using Romanovsky-stained smears alone, the monocyte-like features and absolute increase in monocyte count in acute granulocytic leukemia may lead the leukemia to be misdiagnosed as acute myelomonocytic leukemia.
This occurred in 5 of the 13 cases in the study. The presence of granulocyte- and monocyte-specific esterase in single cells supports the notion of a common origin for granulocytes and monocytes.
The authors conclude that the combined esterase reaction can distinguish between acute granulocytic leukemia, acute monocytic leukemia, and acute myelomonocytic leukemia.

Answer: The factor of safety in a plumbing system and determination of the upper limit of service for a 3-inch soil stack. 146. Establishment of a factor of safety.
Explanation:
The manipulated variable in the investigation is the diameter of the rubber tubing to determine its impact on siphoning time.
In the investigation exploring the impact of rubber tubing diameter on the time required to siphon water from a container, the manipulated variable is the diameter of the tubing. This variable is intentionally altered by the researcher to assess its influence on the siphoning process. By testing various tubing diameters, the researchers aim to observe any patterns or trends regarding the time it takes for water to be siphoned out.
This investigation seeks to determine if there is a correlation between tubing diameter and siphoning time. Controlling other factors, such as the volume of water, height difference, and tubing length, allows for a focused examination of the specific impact of tubing diameter on the efficiency of the siphoning process.

The movement of the dyes would change in the negative if a fluid with higher viscosity is used. i.e lower movement of the dye through the medium
This is further explained below.
What kind of effects does viscosity have on the flow of fluid?Generally, One way to think about viscosity is as a measurement of the resistance that a fluid has to flow through it.
When compared to a fluid with lower viscosity, a liquid with a surface tension has a lower flow rate but a higher resistance, which is akin to having more friction.
This resistance may be thought of as the equivalent of having greater friction. To provide an example using language that is more accessible to people, we may state that the viscosity of a fluid is lower when it moves through its environment in a more orderly fashion.

Precision, on the other hand, refers to the variance you observe when you evaluate the same part again with the same tool. Accuracy, on the other hand, refers to the difference between both the measure and the part's real value.
Because there is less room for error in the approximated digit, measurements with more significant figures have higher repeatability or precision. A value with more significant figures is just more exact than a calculated values with fewer significant figures; it is not automatically more accurate. A value of 1.2 m, for instance, was measured using a less accurate measurement instrument, while a value of 1.5422 m was measured using a more exact measuring tool.
