Answer:
B. Members of Plantae and some members of Protista are autotrophs.
Explanation:
All the plants and some protists like euglena are autotrophs i. e. make their own food with the help of chloroplast in the process of photosynthesis. All members of kingdom Plantae cannot move from one place to another like animals. Protists are the organisms which is made of one cell and they have the characteristics of fungi, plants and animals.
Explanation:
Fertilization, pictured in Figure 24.23a is the process in which gametes (an egg and sperm) fuse to form a zygote. The egg and sperm each contain one set of chromosomes. To ensure that the offspring has only one complete diploid set of chromosomes, only one sperm must fuse with one egg. In mammals, the egg is protected by a layer of extracellular matrix consisting mainly of glycoproteins called the zona pellucida. When a sperm binds to the zona pellucida, a series of biochemical events, called the acrosomal reactions, take place. In placental mammals, the acrosome contains digestive enzymes that initiate the degradation of the glycoprotein matrix protecting the egg and allowing the sperm plasma membrane to fuse with the egg plasma membrane, as illustrated in Figure 24.23b. The fusion of these two membranes creates an opening through which the sperm nucleus is transferred into the ovum. The nuclear membranes of the egg and sperm break down and the two haploid genomes condense to form a diploid genome.
Recall that a period is horizontal, and a group is vertical.
So if cobalt is moving "down" a period, it would be most logical to say that it would be Ni, or nickel. It could also be Copper, Zinc, Gallium, and so on. Make sense?
• The kingdom PROTISTA includes autotrophic and heterotrophic, unicellular and multicellular organisms.
• The most specific taxonomic level is SPECIES
• The characteristic of all living things is PRODUCE OFFSPRING BY MEANS OF SEXUAL REPRODUCTION
• In 1990 —> SOME ORGANISMS WHICH WERE PREVIOUSLY CHARACTERIZED TOGETHER WERE DETERMINED TO BE GENETICALLY VERY DIFFERENT
• a virus is not living because it does not have —> GENETIC MATERIAL
• An amoeba, oak tree, squirrel, and mildew are classified in the same —> DOMAIN
* for the rest of the questions, im assuming there’s a picture, could you provide one?*
