Answer:
Both psudopodes and flagella are used for movement, but only psudopodes are used to engulf food.
Both pseudopods and flagella are used for movement. Pseudopods are temporary and used to engulf food, while flagella are hair-like structures used for locomotion in dinoflagellates.
Explanation:The question pertains to the comparison of pseudopods in sarcodina and flagella in dinoflagellates. The correct answer to the question is that both pseudopods and flagella are used for movement, but only pseudopods are used to engulf food. Pseudopods are temporary, foot-like extensions of the cytoplasm enabling sarcodina to move and capture prey. Conversely, flagella are long, hair-like structures that allow dinoflagellates to move through their aquatic environments. While flagella contribute to the locomotion of dinoflagellates, they are not involved in engulfing food.
why do the more complex sugar disaccharides store more energy than monosaccharides
Answer: Because Disaccharides have more chemical bonds
Explanation:
Answer: Because they have more bonds in them
Explanation:
More complex sugars have more bonds available that can be broken down into more simpler form.
When more complex carbohydrates are broken down into simpler carbohydrates then energy is released from the breaking of complex bonds into simpler form.
This is the reason why disaccharides have more energy as compared to that of monosaccharides.

Directions: Complete a Punnett square for the following genetics problems and provide genotypic and phenotypic ratios of offspring.
In rabbits, short hair (S) is dominant over long hair (s). What genotype and phenotype ratios are expected from a cross between two heterozygous shorthaired rabbits?
In sheep, white wool (W) is dominant over black wool (w). What genotype and phenotype ratios are expected from a cross between a heterozygous sheep with white wool and sheep with black wool?
In some plants, green pod color (G) is dominant to yellow pod color (g). If an individual that was heterozygous for green pods were crossed with one that was homozygous for green pods, identify the genotype and phenotype ratios of the offspring.
In some plants, having brown seeds (B) is dominant to having white seeds (b). What are the genotype and phenotype ratios that would be expected from a cross between an individual that is homozygous for brown seeds and one that has white seeds?

Thank you!! Will give Brainliest if possible!
Answer:
Sorry I couldn't draw the punnett squares. Also I'm not sure if you need to reduce the ratios or change them into percents but hopefully this helps
1. S s
S SS Ss
s Ss ss
Genotypic ratio- 1 SS: 2 Ss: 1 ss
Phenotypic ratio- 3 short haired: 1 long haired
2. W w
w Ww ww
w Ww ww
Genotypic ratio- 2 Ww: 2 ww
Phenotypic ratio- 2 white wool: 2 black wool
3. G g
G GG Gg
G GG Gg
Genotypic ratio- 2 GG: 2 Gg
Phenotypic ratio- 4 green pods: 0 yellow pods
4. B B
b Bb Bb
b Bb Bb
Genotypic ratio- 4 Bb: 0 bb: 0 BB
Phenotypic ratio- 4 brown seeds: 0 white seeds
Using Punnett squares for various genetic traits in animals and plants, you can predict the genotypic and phenotypic ratios of the offspring. In each case, allele dominance determines the phenotypic outcome.
Explanation:Let's complete the Punnett squares for the given genetic problems to determine the genotypic and phenotypic ratios of the offspring.
1. Short Hair (S) vs Long Hair (s) in Rabbits:
Heterozygous short-haired rabbits have a genotype of Ss. When we cross two Ss rabbits, the Punnett square yields the following genotypes: SS, Ss, Ss and ss. This results in a genotypic ratio of 1 SS : 2 Ss : 1 ss. Because the short hair gene (S) is dominant, the phenotypic ratio will be 3 short-haired to 1 long-haired.
2. White Wool (W) vs Black Wool (w) in Sheep:
When we cross a heterozygous white wool sheep (Ww) with a black wool sheep (ww), the Punnett square yields genotypes: Ww and ww. Therefore, the genotypic ratio is 1 Ww : 1 ww. Since white wool is dominant, the phenotypic ratio is 1 white : 1 black.
3. Green Pod (G) vs Yellow Pod (g) in Plants:
Your cross is between a heterozygous green pod plant (Gg) and a homozygous green pod plant (GG). This yields genotypes: GG and Gg, hence a genotypic ratio of 1 GG : 1 Gg. As green is dominant, all offspring should be green in phenotype.
4. Brown Seeds (B) vs White Seeds (b) in Plants:
The cross is between a homozygous brown seed plant (BB) and a white seed plant (bb), resulting in all offspring being heterozygous (Bb). Therefore, the genotypic ratio is 1 Bb, and as brown is dominant, all offspring will have brown seeds.

Explanation:
In an experiment, some magnesium ribbon is weighed and its mass is recorded. It is then placed in a crucible and heated. Once hot enough, it combines with oxygen to form magnesium oxide (MgO). Observe the data table provided. Why does the law of conservation of mass appear violated?
Answer:
B) Some of the product escaped as a vapor from the crucible.
Explanation:
Impurities and magnesium not reacting completely would not lead to less product necessarily. Nitrogen gas getting into the crucible would lead to a larger product mass.
The perceived violation of the law of conservation of mass in the experiment is due to the absorption of oxygen from the surroundings. This makes the final product's mass greater than the original magnesium, but it does not violate the law as total mass before and after the reaction is the same.
Explanation:The reason it may appear that the law of conservation of mass is 'violated' in this experiment could be due to the absorption of oxygen from the air to form magnesium oxide. The original mass was just the magnesium ribbon, but after heating, the resulting compound included both the mass of magnesium and the mass of the oxygen it combined with from the air, which made it appear as though the mass had increased. However, this doesn't violate the law of conservation of mass because the mass of the magnesium plus the mass of the oxygen combined equals the mass of the magnesium oxide product. The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction, and this principle still holds true in this scenario.

To what conclusions did Redi and Pasteur's experiments lead?
Maggots spontaneously generate from meat.
Life can spontaneously generate.
Microbes spontaneously generate from broth
Life does not spontaneously generate.
Answer:
A. Maggots spontaneously generate from meat.
Experiments by Redi and Pasteur's disproved spontaneous generation, showing maggots come from flies and microorganisms from existing life, summarizing that 'Life only comes from life'.
Explanation:Experiments Disproving Spontaneous GenerationThe experiments conducted by Francesco Redi and Louis Pasteur led to the conclusion that life does not spontaneously generate. Redi's experiment involving meat, maggots, and flies demonstrated that maggots are the offspring of flies and do not spontaneously appear from meat. Similarly, Pasteur's swan-neck flask experiment showed that microorganisms did not appear in a sterilized broth unless it was exposed to air, indicating that microbial life comes from existing life and not from non-living matter. Pasteur concluded, "Omne vivum ex vivo" (Life only comes from life). These experiments were pivotal in debunking the long-held theory of spontaneous generation.

Invasive species:
A) Can increase competition
B) Help prevent extinction
C) Reduce disease in a population
D) Are not native to the environment
Answer:
I think that the answers are A and D.
For option A, we can come to the conclusion by thinking about the effects of invasive species. For example, when an invasive species appears in a specific environment and unfortunately feed on the same kind of plant as the native species, it will lead to the fact that they have to compete more in order to survive.
For option B, we can clearly see that it's wrong. From the point above, we can also predict that there is a high chance the invasive species will win the competition, resulting in the decrease population of the native specices that couldn't compete.
For option C, it is also impossible, instead the opposite is more likely to happen, because as we know, the native species, after a long period of evolution, became almost perfectly adapted to the environment, the appearance of invasive species may help the diseases that the native species weren't immune to spread faster, decreasing the population.
And I guess option D is obviously correct, no need to explain.

Answer:
A
Explanation: bc it has more stuff to hit
The wave with the longest wavelength will probably be diffracted the most. This is because diffraction, or the bending of waves around obstacles, is closely related to the wavelength of the wave. The longer the wavelength, the more a wave tends to diffract.
Explanation:The wave that will probably be diffracted the most is a. the wave with the longest wavelength. Diffraction is the bending or spreading of waves as they encounter an obstacle or gap. This concept is closely related to the wavelength of a wave, which is the distance between one wave crest and the next. The longer the wavelength, the more a wave tends to spread out or diffract around obstacles. This is why low-frequency sound waves (which have long wavelengths) can easily be heard around corners, but high-frequency light waves (with their shorter wavelengths) are largely blocked by obstacles.
